Terms of Service

Last updated 20 August 2026. These terms cover three separate things: this website, the free tool, and paid licences. They are different, and the rules differ.

1. Who you are dealing with

Curbcut is software published by an independent sole trader registered in Ukraine («we», «us»). Our contact address for every purpose in these terms is hello@curbcut.org. We answer in English. Full registration details are provided on request and are shown on every purchase receipt.

Paid licences are not sold by us directly. They are sold by Paddle.com Market Ltd acting as the merchant of record and reseller. Paddle is the seller on your invoice, handles payment and taxes, and its own buyer terms govern the purchase itself. Where Paddle’s buyer terms and these terms conflict on anything to do with payment, refunds or tax, Paddle’s terms win.

2. The free tool

The Curbcut command line tool is published under the MIT licence. The licence text in the repository is the whole agreement for it. In particular, the MIT licence provides the software «as is», without warranty of any kind. Nothing on this website adds a warranty to it.

You may use it commercially, modify it and redistribute it. You do not need our permission and you do not need to tell us.

3. What Curbcut is not

This matters more here than in most software, so it is stated plainly.

• It is not legal advice. We are not lawyers and we are not your lawyer. Whether the European Accessibility Act applies to you, and what it requires of you, is a legal question about your business.
• It is not a certification. We are not a conformity assessment body. We are not affiliated with, endorsed by or accredited by ETSI, CEN, CENELEC, the European Commission or any national market surveillance authority. Output from Curbcut is not a certificate and does not carry regulatory standing.
• It is not a guarantee of compliance. Automated testing detects only a portion of accessibility barriers. A clean Curbcut run does not mean your service conforms to EN 301 549, and we make no such claim on your behalf. Any accessibility statement you publish is your statement, published by you, and you are responsible for its accuracy.

4. Paid subscriptions

Monitor and Agency are hosted subscriptions, billed once a year and renewing automatically until you cancel. Monitor covers one organisation and the websites it owns or operates. Agency additionally covers websites you work on for clients.

At the time of writing neither is available and neither is taking payment. This section describes the terms that will apply when they open, so that anyone deciding whether to wait can read them in advance. The command line tool is available today and is covered by section 2, not by this one.

You can cancel at any time, from the link on your Paddle receipt or by emailing us. Cancelling stops the next renewal; it does not end the licence you have already paid for, which runs to the end of its term. We do not charge a cancellation fee and we do not require notice.

The subscription exists because conformance is not a one-off event. Your site changes, the harmonised standard is revised, and a conformance claim more than a year old is evidence of very little. If that is not what you want, the free tier is MIT licensed and always will be.

You may not resell or resell access to the hosted service, or share account credentials outside your organisation. Everything MIT-licensed stays MIT-licensed and is unaffected by this clause: the command line tool, including the PDF report, remains free for any use, commercial use included, whether or not you ever pay us anything.

5. Refunds

Refunds are handled by Paddle. Ask us at hello@curbcut.org within 30 days of purchase and we will approve a full refund, no reason required and no argument. If you are a consumer in the EU or UK, your statutory withdrawal rights apply in addition to this and are not reduced by it.

6. Availability

The free tool runs on your machine and does not depend on us being online. This website and licence delivery may be unavailable at times. We do not offer a service level commitment and none should be inferred.

7. Liability

To the fullest extent the law permits, our total liability arising out of these terms is limited to the amount you actually paid us in the twelve months before the claim. For users of the free tool, that amount is zero, which is the bargain the MIT licence describes.

We do not exclude liability for death or personal injury caused by negligence, for fraud, or for anything else that cannot lawfully be excluded. If you are a consumer, your mandatory statutory rights are unaffected by anything in this section.

8. Changes

We may revise these terms. The date at the top changes when we do. Material changes will not be applied retroactively to a licence you have already bought.

9. Governing law

These terms are governed by the law of Ukraine. If you are a consumer resident in the EU or UK, this does not deprive you of the protection of mandatory consumer law in your own country, and you may bring proceedings there.

10. Complaints

Write to hello@curbcut.org. We reply to everything. If you are an EU consumer and we cannot resolve it between us, you may also use the European Commission’s online dispute resolution platform.
