Terms of Service

Last updated: September 12, 2026

1. Acceptance of Terms

Plain English: using this site means you agree to these rules.

By accessing or using GADGET UP (the "Service"), including generating invention plans, browsing the gallery, or saving builds, you agree to be bound by these Terms of Service and our Privacy Policy. If you do not agree, do not use the Service.

2. Service Description

GADGET UP is an AI-powered hobby platform. You describe an invention idea; the Service generates a suggested plan that may include a parts list with estimated prices, build steps, wiring, electronics suggestions, firmware code, engineering figures, a safety review, 3D-printing and manufacturing guidance, and an interactive 3D model. The Service currently provides plans and links to third-party retailers. You can reserve a parts kit; that reservation takes no money and creates no obligation on either side. If we ever start shipping kits, these Terms will gain a shipping, returns and product-safety section before the first box goes out.

Everything it produces is generated by artificial intelligence and by automated calculation, and none of it is checked by a person before you see it. Section 3 says exactly which AI models write it, section 3b covers the real-world measurements it estimates for you, and section 3c covers the printing and manufacturing figures. Read those three before you spend money on parts or cut anything.

Most features are paid for with BuildBux, the site's prepaid digital credit, which arrives free, is earned, or comes as the monthly allowance included with a paid subscription — see sections 2b, 2c, and 2d. Two features meter you instead of charging a flat price: the live Bench Chat (section 2g) and optional pay-as-you-go pricing (section 2h).

2b. BuildBux — Prepaid Digital Credits

Plain English: BuildBux are tokens for this site only. They are not money, you cannot cash them out, and they die with the account.

BuildBux are a prepaid digital credit usable only inside GADGET UP. Holding BuildBux gives you a limited, personal, non-exclusive, non-transferable, revocable licence to use paid features of the Service — nothing more. You do not own the BuildBux themselves and they are not your property.

BuildBux reach your account in three ways. Free, because we granted them or you earned them. As the monthly allowance included with a paid subscription under section 2c — subscribing buys you a month of the Service, and the BuildBux are what that month gives you, not a separate product you have purchased. Or as a one-time top-up if you have switched on pay-as-you-go pricing under section 2h, which is the only place BuildBux are bought directly.

However they arrive, everything in this section applies to them: they are a licence to use paid features, not property, not money, and not redeemable for cash. A top-up is a completed purchase of a digital credit that is delivered immediately, so it is non-refundable once delivered except for a billing error (section 2c) or where the law says otherwise.

2c. Subscriptions — Monthly Plans, Automatic Renewal, and Cancelling

Plain English: these are monthly plans, not one-time packs. Your card gets charged the same amount on the same date every month, automatically, until you cancel. Cancel in one click, keep the month you already paid for, no partial-month refunds. On Starter and Starter + your BuildBux expire every month — the new month's BuildBux replace what is left instead of stacking on it, and we email you before it happens. On Pro and Pro Builder + they roll over. Whichever plan you are on, cancelling does not empty your balance.

Paid plans are not open yet, and until they are, nothing on this site can charge you. Choosing a plan on the pricing page today reserves a place in line and takes no payment method and no money. This section is the agreement that will govern a subscription from the moment they open — it is written first on purpose, because the renewal terms have to be in front of you before you can agree to them, not after.

Paying by hand. Until checkout opens, the one way to start a paid plan is to send us the plan's monthly price directly (for example by Cash App or Venmo) and have us switch it on by hand. That buys one month of that plan at the listed price. It does not renew by itself: we email you before the month ends, and nothing further happens unless you send another payment. Refunds on a hand payment follow "Billing errors" and "Refunds otherwise" below. Hand payments are received by the adult account holder named in the acknowledgement email we send when the plan is switched on.

THIS IS AN AUTOMATICALLY RENEWING SUBSCRIPTION. When you subscribe, you are starting a recurring monthly charge, not making a single purchase. Your payment method is charged the plan price at checkout and then automatically once every month, on the same date each month, for the same amount, with no end date. The subscription renews by itself and keeps renewing until you cancel it. We do not ask you to approve each renewal — that is what subscribing means, and that is what the agreement box at checkout confirms you understand.

The plans. Prices are in U.S. dollars, per month, and exclude any tax that may apply. The billing term is one month. Each plan's BuildBux are delivered on each successful monthly payment — added to your balance on a plan that rolls over, and replacing it on a plan that does not:

Building an invention costs 5 BuildBux, and ordering your own build — parts list, instructions, Amazon cart, and the 3D file — is free, so "builds" above is simply that plan's monthly BuildBux divided by the 5 a build costs. The price shown at checkout, next to the agreement box, is the price that governs that subscription until we change it under "Price changes" below. Labels such as "MOST POPULAR" and "BEST VALUE" are descriptive names for the plans — they are not promises of savings, value, performance, speed, or results.

How to cancel: one click, and we mean one click. Cancelling is a single action. It takes no phone call, no live chat, no explanation, no reason, no survey, and no screen full of offers to stay. Any of these works, and all of them are equally valid:

Cancelling is never harder than signing up was, and it is never in a place signing up was not. Where you cancel by email rather than by button we act within 2 business days, and any request we receive at least 48 hours before your next renewal date stops that renewal. We email you a confirmation either way. This is what the FTC's click-to-cancel rule and California's Automatic Renewal Law require — a simple cancellation mechanism, in the same medium you signed up in, with no retention offer standing between you and the exit — and it is also just how we want to run this.

What cancelling does, and what it does not do. Read this bit, because two things happen and only one of them is instant.

Rollover — which plans keep unused BuildBux and which do not. People pay for this, so it is written here with no room to argue about it.

Exactly when a balance is replaced, and the five times it is not. Replacing a balance is the only thing on GADGET UP that takes something away from you, so it happens in one place, under one set of rules, and we would rather over-explain them than have you find them out afterwards. A balance is replaced only at the moment a monthly payment on a non-rollover plan actually succeeds, and never at any other moment. In particular:

Every replacement is recorded with the balance before, the amount that expired, and the balance after. If we ever get one wrong, email GadgetUpSupport@gmail.com and we put the BuildBux back from that record — we do not ask you to prove what your balance was.

What happens to your BuildBux when a plan ends. Rollover, where you have it, is a feature of the plan and stops when the plan does: once the subscription ends, no new monthly BuildBux arrive and nothing rolls anywhere. But ending a subscription does not empty your account. If you cancel and the paid period runs out, or a payment fails and the plan lapses, the BuildBux already in your account — rolled over or not — stay there and remain spendable on a free account. We do not zero a balance for cancelling, and we would rather say so in the contract than leave you guessing. BuildBux still are not money, still have no cash value, and still cannot be refunded, cashed out, or transferred (section 2b), and they do end with the account itself if you delete it or we terminate it for cause under Forfeiture below.

Free accounts, and accounts whose plan has ended, work the simpler way: there is nothing to roll over, and instead, if your balance is under 5 BuildBux when a new month begins, we top it back up to 5. That is a top-up to a floor, not an addition, so it cannot be stacked either. That floor applies to every account that is not on founder access, so it is also the safety net underneath the paid plans.

What the paid plans actually get you, described honestly. Beyond the monthly BuildBux: (1) Bench Chat, on Starter + and above. The live build chat described in section 2g is available on Starter +, Pro, and Pro Builder +, and to accounts with unlimited access. It is not included with the Starter plan or with free accounts. Bench Chat is still metered at 1 BuildBux per two minutes of model runtime on every plan that has it — the plan unlocks the feature, it does not make the chat free. (2) Queue priority when the engine is busy. When more builds are running at once than the engine comfortably handles, requests are ordered by plan — higher plans wait less than lower ones, and Pro Builder + is not held back at all. The Starter plan sits at the same level as free accounts and does not include a queue advantage. This affects your place in line only. It is not a promise of any particular speed, generation time, throughput, uptime, or guaranteed availability, and when the engine is not busy nobody is waiting and priority changes nothing. (3) Rollover on Pro and Pro Builder +, as described above; Starter and Starter + do not have it. (4) Featured placement in the Market for Pro Builder +, which is NOT switched on and is not part of what you are paying for today. We are saying that here rather than letting you infer it: the Market currently lists every published build in the order it was published, with no plan-based promotion of any kind, and there is no Pro Builder badge on listings. If we ever switch featuring on it will be editorial, applied at our discretion, and never a guarantee of visibility, ranking, traffic, views, or sales — and we will say so on the pricing page before we start describing it as a perk. Do not subscribe to Pro Builder + for featuring. Subscribe to it for the 100 BuildBux, the rollover, and the top of the queue, all three of which are real today. (5) STL files without ordering, on Pro and Pro Builder +. The 3D print file already comes free with any build you order, on every plan and on free accounts; what Pro and Pro Builder + add is the ability to export the STL for a build you have not ordered. Perks depend on your subscription being active and paid, and end when it ends.

Price changes. We may change plan prices or the BuildBux a plan includes. If we do, we will email the address on your account, and post it on the pricing page, at least 30 days before the change takes effect, telling you the new price, when it starts, and how to cancel. A new price only ever applies from a renewal that happens after that notice — we will never charge you a higher amount for a month you were not told about first. If you do not want the new price, cancel before the effective date; staying subscribed past it means you accept it. Where the law where you live requires your fresh consent to a price increase, we will get that consent instead.

Billing errors. If a charge looks wrong — a duplicate, a charge after you cancelled, the wrong plan, or an amount you do not recognise — email GadgetUpSupport@gmail.com within 60 days of the charge appearing on your statement. Tell us the date, the amount, and the email on the account. We will investigate and refund anything that was genuinely charged in error. This window is our own service promise; it does not shorten or replace any longer right you have under law or with your card issuer.

Refunds otherwise. Apart from billing errors and anything the law requires, monthly fees are non-refundable once charged, because the month's BuildBux and perks are delivered as soon as the payment succeeds. Nothing here removes a statutory cancellation, cooling-off, or consumer-protection right you have where you live; where such a right applies, it wins.

Failed payments. If a renewal payment is declined or reversed, we may retry it, and we may pause or end your subscription and its perks until payment succeeds. BuildBux already spent are not clawed back, but BuildBux credited for a month whose payment was reversed may be removed.

Forfeiture. If we suspend or terminate your account for cause — violating these Terms, abusing the AI engine, fraud, or a payment chargeback — the subscription ends and any unused BuildBux in that account, whether they came from a plan, a grant, or were earned, are forfeited without refund.

Who takes the payment. Payments and recurring charges are processed by Square, a third-party payment processor, under its own terms and privacy policy. We never receive or store your full card details; Square holds the payment method used for your renewals. You must be the cardholder or have the cardholder's permission to subscribe, and if you are under 18 you must have a parent or guardian's permission before starting any subscription.

Your auto-renewal rights under state law. Several U.S. states — including California, whose Automatic Renewal Law is the strictest — require that automatic-renewal terms be disclosed clearly and conspicuously before you pay, that you give affirmative consent to those terms specifically, that you get an acknowledgement you can keep, and that cancelling online is easy. We have written this section and the checkout to meet those rules: the renewal terms, price, frequency, and cancellation policy appear next to the agreement box before any payment is taken; the box is unticked until you tick it; and we email you an acknowledgement containing the auto-renewal terms, the cancellation policy, and how to cancel, in a form you can save. Nothing in these Terms limits any right an automatic-renewal or consumer-protection law gives you, and where such a law conflicts with these Terms, the law wins.

2d. The Agreement Box at Checkout (Clickwrap)

Plain English: ticking the box is your signature. It means yes to these Terms and yes to being charged every month until you cancel.

Before you can start a subscription, you must tick the agreement box shown at checkout. It is unticked by default, it is required, and there is no way to subscribe without it. The box sits next to the plan name, the monthly price, and the statement that the plan is a monthly subscription that renews automatically until you cancel.

Ticking that box and continuing to payment does three things at once:

We keep a record of the plan, price, and terms shown to you and the moment you ticked the box, and that record is available to you on request with the auto-renewal terms, the cancellation policy, and how to cancel. You can withdraw your authorisation for future charges at any time by cancelling under section 2c; withdrawing it does not undo charges already made for months already provided.

2e. One Account Per Person, and How Free BuildBux Are Protected

Plain English: one account each. Making extra accounts to collect the free 5 BuildBux over and over is cheating, and we can hold back or take back that free credit. Anything you actually paid for is safe, and a person will read your appeal.

One account per person. You may hold one GADGET UP account. Creating or using more than one account — a second email address, a plus-address, a spare device, a friend's details, or anyone else's name — in order to collect the welcome grant, a referral reward, a promo code, or any other free BuildBux more than once is a breach of these Terms.

What we may do about it. Where our checks indicate that an account is a duplicate or that free credit is being farmed, we may reduce or withhold the welcome grant and any other promotional credit on that account, reverse promotional credit already granted, refuse a referral reward or a promo code, and close duplicate accounts while keeping the oldest one. We may do this without notice, and doing it once does not stop us doing it again.

What is actually happening today, as opposed to what we are allowed to do. Everything in this section is a right we reserve. At the moment we are not using it: every signup receives the full welcome grant whatever the checks score, the checks only raise a flag for a person to look at, and even if we do switch reduction on, the smallest grant any account can receive is 2 BuildBux rather than none. Section 4 of the Privacy Policy says the same thing and is the page that will change first if this does.

Some of this is decided automatically. To decide whether a new account should receive free credit, we run automated checks on the registration details you give us and on signals taken from the request itself — your IP address, the approximate country, region, and city that address maps to, and a device signal. The result of those checks may be that free credit is reduced, withheld, or reversed, and no person necessarily reviews that outcome before it takes effect. The Privacy Policy sets out exactly what is collected for this, why, and how long each item is kept.

You can appeal to a human, and you should. Automated checks get things wrong. Several classmates on one school network, or a family sharing one home connection, look identical from the outside — that is normal here and it is not fraud. If free credit was withheld or reversed and you think that is wrong, email GadgetUpSupport@gmail.com with the word APPEAL and your username, from the address on your account. A person reads it, replies, and puts the credit back where the check got it wrong. Appealing is free, there is no limit on how often you may appeal, and appealing never counts against you.

Promotional credit is a gift, not a purchase. The welcome grant, the monthly top-up to the free floor, referral rewards, promo-code credit, and BuildBux earned by publishing or by someone ordering your build are all promotional. You never paid for them, they have no cash value, they are not refundable in any form, and we may withhold, reduce, or reverse them for abuse of these Terms.

What an anti-fraud flag can never touch: anything you paid for. We are stating this plainly because taking away something you paid money for is a completely different matter from declining to hand out a gift. An anti-fraud flag about free credit does not cancel your subscription, does not stop your plan's monthly BuildBux from arriving, does not remove BuildBux already delivered for a month you paid for, and does not take back builds you already ordered or published. Paid subscription benefits are affected only by the subscription rules in section 2c — cancellation, failed payment, and forfeiture on termination for cause — and never by an automated anti-fraud decision about free credit on its own. If a paid benefit disappears and an anti-fraud flag is the reason, that is our mistake: email us and we will restore it.

Deliberate, repeated fraud is the one exception, and it takes a person. Nothing above prevents us from ending an account for cause under the Forfeiture paragraph of section 2c where someone deliberately and repeatedly defrauds the Service or charges back a payment. That is a decision a human makes and tells you about in writing, not something an automated flag does by itself, and it is appealable to the same address.

2f. Your Account — Accurate Information, What Is Public, and Keeping It Secure

Plain English: register with your real details, pick a password nobody can guess, keep it to yourself, and sign out on school computers. Your username is public on the Market. Your full name and email are not. What happens under your login counts as you.

2g. Bench Chat — Metered by Model Runtime, and Exactly How the Meter Works

Plain English: Bench Chat costs 1 BuildBux for every two minutes the AI actually spends thinking. Reading, typing and leaving the tab open cost nothing. Anything less than a full two minutes is free, a failed answer is free, and it can never take you below zero.

What it is. Bench Chat is a chat attached to one specific build. It is given that build's real parts list, real wiring, real steps, real firmware and real engineering numbers before you type anything, so it can answer questions about the machine in front of you rather than guessing. It is available on the Starter +, Pro, and Pro Builder + plans and to accounts with unlimited access; it is not part of the free tier or the Starter plan. Because the chat can quote the wiring and the parts, it sits behind the same paid door as the rest of the build package.

The price, stated exactly. 1 BuildBux per two minutes of model runtime. "Model runtime" means the time an AI request is actually in flight — the seconds the model is generating your answer. It is not wall-clock time and it is not how long the chat window is open.

How runtime is measured. Our server starts a clock the moment it sends your question to the AI model and stops it the moment that model's answer finishes arriving. It counts in milliseconds, on our side, per question, and it adds those up across the session. Nothing else is counted: not the time you spend reading or typing, not the time the page spends loading, not any part of the request that happens before or after the model itself is working. If a request never produces an answer, its clock is discarded rather than added.

What Bench Chat is not. It is generated by AI, subject to section 3 in full, and it is not engineering, electrical, or safety advice. A pin number, a voltage, or a step it gives you must be verified before you act on it, exactly like the rest of a generated plan. Charges for model runtime already spent are not refundable on the ground that an answer was wrong, incomplete, or not what you hoped for — that is the nature of an AI answer and it is why the rate is metered by the minute rather than sold as a guaranteed result. If the chat is broken rather than merely unhelpful, email us and we will put the BuildBux back.

2h. Pay-As-You-Go Pricing (Optional) and Auto Top-Up

Plain English: instead of a flat 5 BuildBux a build, you can pay for exactly what the AI actually used. It needs a card on file. It is OFF unless you switch it on, and switching it on does not let anything charge your card — that is a second, separate switch you also have to turn on yourself.

Read this first: pay-as-you-go is NOT switched on right now, so nothing in this section is doing anything to your account today. There is no way to turn it on, no card can be held for it, and no automatic charge of any kind can happen. This section is written in advance and in full because it describes the only thing on GADGET UP that would ever let a computer charge a card, and a rule like that belongs in the Terms before the feature exists rather than after. While it is off, every build costs the flat 5 BuildBux described in section 2b. If we switch it on, it arrives switched OFF for you, exactly as described below, and we will say so on the pricing page.

Flat pricing is the default and always stays available. Pay-as-you-go is opt-in, it is off until you turn it on, it never turns itself on, and you can switch back to flat pricing at any time.

The rate, stated exactly. On pay-as-you-go a build costs 1 BuildBux per 10,000 tokens sent to the engine and 1 BuildBux per 7,000 tokens the engine writes back. A "token" is the unit AI providers bill in — roughly three quarters of a word. We use the real token counts the AI provider reports for your build; we do not estimate them and we do not round them up.

A card on file is required. Pay-as-you-go means there has to be something to pay with, so you cannot switch it on without a valid card. Your card is held by Square under its own terms and privacy policy. GADGET UP never sees, stores, or transmits your card number or security code — we hold only a customer reference, a card reference, the card brand, the last four digits, and the expiry month and year Square returns so we can warn you before a card expires.

Turning pay-as-you-go on does not authorise any charge. This is the important one and it is deliberate. Switching to pay-as-you-go changes how your BuildBux are counted. It does not give anything permission to charge your card. If your BuildBux run out with auto top-up off, builds simply stop until you top up by hand. Nothing is charged.

Auto top-up is a separate switch, and it is the only thing on GADGET UP that lets a computer charge your card while you are not watching. It is off by default. Turning it on requires its own screen, its own tick box, and your choice of two numbers: the top-up amount and your monthly ceiling. You give that authorisation knowingly or not at all.

How to turn it off. One click, at any time, including while a build is running — from your account, or from the one-click link in any receipt. There is no confirmation screen, no offer to stay, and nothing to explain. You can switch off auto top-up on its own and stay on pay-as-you-go, or switch pay-as-you-go off entirely and return to flat pricing. If you switch it off during a build, that build is free. We would rather hand you a build than argue about whether your click landed before the tokens did.

Age. If you are under 18 you must have a parent or guardian's permission before you turn on auto top-up, and you must be the cardholder or have the cardholder's permission. This is a standing authorisation to charge a card; do not give it on somebody else's card without asking them.

Availability. Pay-as-you-go is a feature we can switch on, off, or change. Where it is not switched on, flat pricing applies and nothing in this section does anything. Changes to the rate work exactly like price changes in section 2c: notice first, future builds only, never retroactive.

3. AI Content Disclosure — and Which Models Actually Run

Plain English: a machine wrote your plan, and here is exactly which machine. Machines make mistakes. Nobody checks your plan before you see it.

This is an AI product and we are telling you so up front. Every plan, parts list, price estimate, difficulty rating, time estimate, wiring diagram, build step, firmware file, 3D model, safety review, and chat answer on GADGET UP is generated by artificial intelligence, assisted by automated calculation. No human being reviews your build before it reaches you. Output may be incomplete, outdated, or simply wrong. It is an estimate and a starting point, not verified engineering.

Which models write your build:

What we do not claim. GADGET UP makes no performance claim and no guarantee that any generated design will work, fit, be safe, be buildable, be original, or be fit for any purpose. We do not claim any accuracy rate. Where we describe an engine as better, we mean it produces better designs in our own judgement — not that its output is correct. You must independently verify every part, price, measurement, wiring connection, step, and safety consideration before acting on any plan.

Your idea text goes to an AI provider. To generate a plan or a chat answer, what you type is sent to the model provider running that request. Keep it about gadgets: never type passwords, financial details, medical information, or anyone's personal information into the idea box or Bench Chat. The Privacy Policy names every provider involved.

3b. Sizes and Measurements We Estimate For You

Plain English: if you do not give us a measurement, we guess one from a reference table or from the AI. A guess is labelled as a guess. Measure the real thing before you cut, drill, or print.

A design has to be sized against something real — the shelf it mounts on, the bottle it grips, the car it bolts to. Where you have not given us a measurement, the Service works one out, and it does that in one of four ways, in this order:

Every build tells you which of those four it used, and an assumed dimension is labelled on the page as an assumption rather than presented as a fact. That labelling is the whole point: a wrong size that is visible is a five-second fix, and a wrong size that is hidden is a ruined part.

Reference and assumed dimensions are not measurements of your object. Real objects vary by brand, model, year, and country. Measure the actual object with an actual ruler before you cut, drill, print, order, or commit to anything. We are not liable for material, filament, parts, or time wasted on a part built to a dimension you did not check, and "the site said it was 12 cm" is not a substitute for measuring it.

3c. 3D Printing and Manufacturing Guidance Is an Estimate, Not a Certified Plan

Plain English: print times, costs, strength numbers, slicer settings and "will it fit on my bed" are calculated estimates. They are a good starting point. They are not a guarantee, and no engineer signed them off.

The Service produces manufacturing guidance: suggested materials, a suggested process (FDM, resin, laser cutting, CNC, sheet metal, injection moulding), printer-specific settings, layer heights and temperatures, splitting a part that is too big for your bed, estimated print time, estimated material use, estimated cost, and engineering figures such as mass, strength, torque, battery runtime and tip-over angle.

4. Assumption of Risk

Plain English: you build at your own risk. Tools are sharp, electricity bites.

Building physical devices involves inherent risks, including injury from tools, electricity, batteries, moving parts, water, and heights. In particular: lithium (LiPo) batteries can catch fire if punctured, over-charged or charged unattended, so charge them in a fireproof bag and never leave them; propellers and blades spin fast enough to cut; launchers of any kind must never be pointed at a person or animal and need eye protection; lasers above Class 1 can permanently damage eyes; mains voltage can kill and is not for anyone under 18 without a licensed adult; drones and RC aircraft are subject to FAA registration and local rules, which you must check before flying. A safety rating on a plan is a starting point, not a certification. You voluntarily assume all risks arising from your use of any plan generated by the Service. You are solely responsible for your builds, including how they are constructed, powered, and used. Minors must have adult supervision when building. To the maximum extent permitted by law, you release GADGET UP and its operator from any and all claims arising out of or related to your use of generated plans or anything you build from them.

4b. What You Build Is Yours, and It Is Your Responsibility

Plain English: we hand you a plan. What you make with it, and what it does once it exists, is on you.

The Service produces design suggestions and reference information. It does not manufacture, assemble, inspect, test, certify, or supervise anything. We never see what you actually build. Accordingly, and to the fullest extent permitted by law:

This section is in addition to, and does not limit, the Assumption of Risk, No Warranty, Limitation of Liability and Indemnification sections. Nothing in these Terms excludes any liability that cannot lawfully be excluded, and some jurisdictions do not allow certain exclusions, so parts of this section may not apply to you.

5. No Warranty

The Service is provided "AS IS" and "AS AVAILABLE" without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, accuracy, and non-infringement. We do not warrant that the Service will be uninterrupted, error-free, or secure.

6. Limitation of Liability

To the maximum extent permitted by law, GADGET UP and its operator shall not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, data, property, or personal injury, arising out of or relating to the Service or anything built from its output, even if advised of the possibility of such damages. Where liability cannot be fully excluded, total aggregate liability is limited to the greater of the amount in U.S. dollars you actually paid us in the past twelve months or ten U.S. dollars. BuildBux are not money, so any claim measured in BuildBux is valued at the dollar price you actually paid for them, and BuildBux that were granted or earned rather than bought are valued at zero.

7. Indemnification

You agree to defend, indemnify, and hold harmless GADGET UP and its operator from any claims, damages, liabilities, and expenses (including reasonable attorney fees) arising from your use of the Service, your builds, or your violation of these Terms.

8. Acceptable Use and Restricted Content

Plain English: no weapons, nothing to hurt or spy on people. The floor refuses that work.

You may not use the Service to design, request, or build: real weapons or accessories for real weapons (firearms, crossbows, bows, tasers, or anything meant to fire metal, sharp or heavy projectiles at people); explosive, incendiary, or projectile devices intended to harm; devices for drug use; devices for stalking, spying on, or tracking people without consent; safety-critical medical, automotive, or aviation components; or anything illegal where you live. Sports launchers, foam and water blasters, and paintball or airsoft accessories are allowed and are treated as sports equipment, subject to section 4. Automated scraping or abuse of the AI engine is prohibited. You also may not hold more than one account, use another person's account, or register with false details in order to collect free BuildBux more than once — see section 2e for exactly what happens if you do. We may refuse, filter, or block any request at our discretion.

8b. Emails We Send, and How to Stop Them

Plain English: we only email you about your own builds and your account. Reply "stop spam" and we stop.

When you create an account you give us an email address. We use it to send you the build instructions and parts lists for the builds you order, order or reservation confirmations, and occasional notices about your account or the Service (for example, when a feature you asked to be notified about goes live). Emails come from GadgetUpSupport@gmail.com.

Opting out. Every message we send includes both of these, and either one works:

Unsubscribing stops all marketing and update email from us. Your account, your BuildBux balance, and your saved builds are unaffected — you can still use the Service and read your build lists on the site. We do not sell, rent, or share your email address with anyone, and we do not send advertising for other companies.

One exception, and it is in your favour. If you have a paid subscription, we still have to send you the messages that go with it: the acknowledgement of your subscription and its auto-renewal terms, receipts, notices of a price change before it takes effect, failed-payment notices, and your cancellation confirmation. These are billing notices, not marketing, the law requires several of them, and unsubscribing does not switch them off. They stop when your subscription ends.

9. Not Professional Advice

Nothing on the Service is professional engineering, electrical, legal, financial, or safety advice. For anything that could affect the safety of people or property, consult a qualified professional.

10. Age Requirement

The Service is intended for users age 13 and older. If you are under 13, you may not use the Service. If you are under 18, you must have a parent or guardian's permission, and builds require adult supervision.

11. User Content and Intellectual Property

You retain ownership of the invention ideas you submit. By submitting an idea you grant GADGET UP a non-exclusive license to process it to generate your plan. Generated plans are provided for your personal, non-commercial hobby use.

Publishing to the Market. Publishing is your choice and nothing is published unless you publish it. When you do, you grant GADGET UP a non-exclusive, worldwide, royalty-free licence to host, display, and distribute that build on the Service, and to let other users buy it for 4 BuildBux under section 2b — for which you are credited +2 BuildBux per purchase. Your username is shown publicly on anything you publish. You may unpublish a build at any time; unpublishing stops new purchases but does not reach back into copies already bought, and BuildBux already credited to you are yours. You must only publish builds you actually made on this Service, and you must not publish anything that breaks section 8. A buyer receives a personal, non-transferable licence to use the bought build for their own hobby projects; they may not republish it, resell it, or claim it as their own. The publisher warrants they made the build on this Service and have the right to publish it. We may remove a published build at our discretion, including on a copyright complaint.

The GADGET UP name, design, and site content belong to its operator. If you believe content on the Service infringes your copyright, send a DMCA takedown notice to GadgetUpSupport@gmail.com with the work identified, the location of the material, your contact information, and a good-faith statement.

Affiliate links. Parts links may point to Amazon. When our Amazon Associates tag is switched on, GADGET UP earns a commission on qualifying purchases made through those links. It costs you nothing extra, it never changes which parts get picked, and every parts cart that carries the tag says so next to the link.

12. Dispute Resolution — Arbitration and Class Action Waiver

Plain English: if we ever have a serious disagreement, we each agree to settle it one-on-one with an arbitrator, not in a class action.

Any dispute arising out of these Terms or the Service that cannot be resolved informally shall be resolved by binding individual arbitration administered by the American Arbitration Association under its Consumer Arbitration Rules, rather than in court, except that either party may bring an individual claim in small-claims court. GADGET UP pays any arbitration filing fee above the small-claims filing fee. YOU AND GADGET UP EACH WAIVE THE RIGHT TO A JURY TRIAL AND TO PARTICIPATE IN A CLASS ACTION. You may opt out of this arbitration provision by emailing GadgetUpSupport@gmail.com within 30 days of first using the Service.

13. Governing Law and Severability

These Terms are governed by the laws of the United States and the operator's state of residence, without regard to conflict-of-law rules. If any provision is found unenforceable, the remaining provisions stay in full force.

14. Changes and Termination

We may change these Terms at any time, for any reason, without asking you first. We may also change, limit, suspend, or discontinue the Service or any part of it at any time. When we change these Terms we update the date at the top of this page, and the version published here is the one that applies. It is your responsibility to check this page; continuing to use GADGET UP after a change means you accept the changed Terms. If you do not accept them, stop using the Service and close your account. Two carve-outs. A change to the price of a subscription you are already on does not take effect until the notice period in section 2c has run, so a price rise can never be applied to you without warning. And a change to the pay-as-you-go rate in section 2h applies only to builds you run after we tell you, never to ones already billed.
