Terms of Service

Last updated: 23 August 2026

Welcome to Carpy. These terms are a plain-language agreement between you and Carpy ("we"), the operator of carpy.io. By using the app you agree to them.

1. What Carpy is

Carpy generates finger-joint box cut files (SVG) for laser cutters and CNC routers from the dimensions, lid style and material settings you enter, with a 2D and 3D preview. The core generator is free, compartment dividers included. Carpy Premium — a paid subscription — unlocks additional features such as custom divider placement, extra materials, dog-bone reliefs and automatic nesting. The exact feature split and price are shown in the app at the time you subscribe.

2. Your account

Accounts are created by e-mail sign-in link — no passwords. One account is meant for one person; a Premium subscription covers your own use, on any of your devices.

3. Subscriptions, billing, cancellation and refunds

• Payments are processed by Lemon Squeezy as merchant of record — they are the seller on your invoice and handle payment details, taxes/VAT and receipts. Your card details never reach Carpy.
• Premium starts with a 7-day free trial with full access to every paid feature — that week is your evaluation period. Nothing charges you by surprise: you choose the plan at checkout, the first billing date is shown before you confirm, and you get a receipt for every charge. If you don't cancel before the trial ends, billing begins at the monthly price shown at checkout.
• You can cancel any time from the "Manage subscription" page in the app — two clicks, no questions. Cancelling stops all future charges; your Premium access continues to the end of the period you already paid for.
• Because the trial gives you the complete Premium experience before any payment, subscription charges are not refundable once made — except where mandatory consumer law in your jurisdiction grants you a refund right that cannot be excluded (for example the EU/UK statutory rules for digital services), in which case that law prevails. By starting the trial or subscription you get immediate access and consent to the service beginning right away.
• This is a no-refund policy, not a no-responsibility policy: if a fault on our side genuinely prevented you from using what you paid for, write to hello@carpy.io and we'll fix it and find a fair solution.
• If a renewal payment fails, Lemon Squeezy retries your card up to four times over the following two weeks and e-mails you a link to update your payment details. Premium stays active throughout that window; it lapses only if the final attempt also fails, and comes back as soon as a payment goes through.

4. Your designs are yours

Every design and cut file you generate with Carpy — free or Premium — belongs to you. Use them personally or commercially, cut them, sell what you make. We claim no rights over your output and we never see it: designs are computed in your browser and are not uploaded to us.

5. Our code and design are ours

The other side of the same coin: Carpy itself — its code, geometry engine, interface, text and visual design — is protected by copyright, and all rights are reserved. Your subscription or free use gives you a personal, non-transferable right to use the app; it does not transfer any rights in the app itself. Copying, republishing, reselling, redistributing or reverse-engineering Carpy or any substantial part of it, or building a competing service from it, is not permitted. If you'd like to license something we've built, just ask: hello@carpy.io.

6. Check before you cut — safety and accuracy

This part matters, maker to maker. Carpy generates geometry with care, but you are responsible for verifying every file before cutting: check dimensions, joints and material settings, and run a test cut when material or time is at stake. Laser cutters and CNC routers are dangerous machines — operate them according to their manuals and your local safety rules. Carpy provides files and previews only; it does not control your machine.

7. Fair use

Don't attempt to break, overload, resell or copy the service, share one Premium account among many people, or use the app for anything unlawful. We can suspend accounts that abuse the service, and we'll always be reasonable about it.

8. The service, warranties and liability

Carpy is provided "as is". We work hard to keep it accurate and available, but we don't guarantee it will be error-free or uninterrupted. To the maximum extent permitted by law, our total liability for any claim connected to the service is limited to the amount you paid us in the twelve months before the claim, and we are not liable for indirect losses such as wasted material, machine damage or lost profits. Nothing in these terms limits liability that cannot legally be limited, and nothing removes rights you have as a consumer under mandatory local law.

9. Changes

We may improve the app and update these terms as the product evolves. If a change meaningfully affects your rights or your subscription, we'll tell you by e-mail or in the app before it takes effect. The current version always lives at this page.

10. Governing law and contact

These terms are governed by the laws of the Turkish Republic of Northern Cyprus (TRNC), without affecting any mandatory consumer protection you enjoy under the law of the country you live in. Questions, problems, ideas: hello@carpy.io — a maker reads it.
