Terms of Service

Last updated: 9 October 2026

These Terms govern your use of BuildPCB (the "Service"), an online, AI-assisted printed-circuit-board (PCB) design tool operated by SMART GLOBAL PROJECTION, S.L. ("we", "us"), registered in Spain with tax ID B27558758, registered office in Spain (full address available on request at contact@buildpcb.tech). By creating an account or using the Service you agree to these Terms.

1. What BuildPCB is

BuildPCB turns a plain-language description into a complete PCB design — schematic, component placement, copper routing, rule checks and manufacturing files. The Service is a computer-aided electronics design tool.

Designs are generated by artificial intelligence and may contain errors, omissions or unsafe choices. The engine's automated checks reduce mistakes but do not guarantee a correct, safe or manufacturable board. You must have every design reviewed by a qualified electronics professional and/or by your PCB manufacturer before ordering or using it. A pre-manufacturing review is strongly recommended for every board. You use any design at your own risk.

2. Accounts

• You must provide accurate information and are responsible for activity under your account.
• You must be at least 18 years old, or the age of majority in your country.
• Keep your password secure. You may sign in with email and password or with Google.

3. Credits and payments

• The Service runs on credits. Credits are consumed only while the engine performs design work for you (choosing parts, wiring, placing, routing, checking, generating files). Credits are consumable: once used they are gone and are not refundable (see section 4).
• You may buy credit packs, a custom amount, or a monthly subscription. Prices are shown in US dollars and may change; changes never affect credits you already hold.
• An active subscription is required to buy or use credits. Credits never expire while your subscription is active: unused credits (from your plan and from top-ups) roll over from month to month.
• If you cancel your subscription, any credits remaining in your account — including purchased top-ups — are removed when your paid period ends and cannot be recovered. You are shown how many credits you will lose and must confirm it before the cancellation is completed. Until that date you can keep using them. This does not affect your right to a refund of unused credits within 14 days of payment (see the Refund Policy).
• The seller is SMART GLOBAL PROJECTION, S.L. Payments are processed securely by Revolut (Revolut Bank UAB), a licensed bank. Prices are shown in US dollars and include VAT where it applies, and we issue the invoice. We never see or store your card details.
• Subscriptions renew automatically each month until cancelled. You can cancel at any time from Account, effective at the end of the current billing period. You keep access, and any credits you already hold, until that date.
• Auto-recharge (optional, off by default). If you tick "Auto-recharge" when buying a custom amount, you authorise the same amount to be charged to your saved payment method automatically whenever your credit balance runs out, up to three times per day. The terms are shown at checkout and you receive a receipt for every charge. You can switch it off at any time from Account, with immediate effect.

4. Refunds

Credits are consumable. Each credit you use pays for AI processing that our third-party AI provider charges us for at the moment it happens, so credits that have already been used are not refundable. Within 14 days of the payment date you can request a refund of the unused credits of a credit pack, custom amount or subscription payment (the full amount if you have not used any of them). If you are a consumer in the EU or the UK, by buying credits you ask for them to be made available immediately and you accept that you lose the right of withdrawal for the credits you use. Refunds are issued by us to your original payment method. See the full Refund Policy for details and how to request one.

5. Acceptable use

You agree not to use the Service to design hardware that is unlawful in your jurisdiction, to infringe others' intellectual property, to commit fraud or pay with a payment method you are not authorised to use, to attempt to gain unauthorised access to, disrupt or reverse-engineer the Service, or to resell access without our written permission.

6. Your designs and our disclaimer

You own the designs you create and the output files you download. The Service itself — its software, engine, website and the BuildPCB name and logo — belongs to us and is protected by intellectual-property laws; these Terms do not transfer any of it to you. You are solely responsible for the boards you design, order and manufacture using the Service. Because designs are produced by AI and may contain errors, you must verify that a design is correct, safe, functional and legally compliant — through professional and/or manufacturer review — before manufacturing or use.

The Service and all generated designs are provided "as is", with no warranty of any kind, express or implied, including fitness for a particular purpose. We accept no responsibility or liability for any board designed, ordered or built with the Service, nor for any cost, loss, injury or damage arising from it, including manufacturing costs and defective or non-functional boards.

7. Availability

We aim for high availability but the Service is provided "as is" and "as available". Because each design runs on a shared engine, one design is processed at a time and you may occasionally need to wait. We may perform maintenance that briefly interrupts the Service.

8. Limitation of liability

To the maximum extent permitted by law, our total liability for any claim relating to the Service is limited to the amount you paid us in the three months before the claim. We are not liable for indirect or consequential damages, or for the cost of manufacturing a design.

9. Termination

You may close your account at any time. We may suspend or close an account that breaches these Terms, including in cases of non-payment, chargebacks or fraud. On closure, unused purchased credits may be refunded at our discretion where required by law.

10. Changes and contact

We may update these Terms; material changes will be announced on this page, and continuing to use the Service after a change means you accept the updated Terms. Questions: contact@buildpcb.tech. These Terms are governed by the laws of Spain, and disputes are subject to the competent courts of the operator's registered seat.
