Terms and conditions

1. Who provides the service

Cairn and the cairnflow.app site are operated by The No-Code Company OÜ ("we").

By downloading, installing or using Cairn, or by buying a license, you accept these terms. If you don't agree, don't use the application.

2. What Cairn is

Cairn is a desktop application for macOS for discovery wireframing: you model the structure of your product (data, roles and flows) and run it to catch what's missing before you build. There's a free plan and a paid plan (Pro).

3. Plans and license

• Free. Free of charge: 1 project, up to 2 scenarios, unlimited nodes and blocks. No importing, exporting or saving to file.
• Pro. A one-time payment license (39€): unlimited projects and scenarios, import/export and save to file, and the rest of the Pro features.

When you buy Pro we grant you a perpetual, personal and non-exclusive license to use Cairn. The license is for your use (you can activate it on your own machines and move it by deactivating and reactivating it). You may not resell it, sublicense it, share your key publicly or attempt to circumvent the license checks.

4. One-time payment, perpetual use and updates

This is the important part, so we say it clearly:

• You pay once and the version is yours forever. Your Pro license doesn't expire: the version you have will keep working perpetually, with no subscription.
• It includes one year of updates from the purchase date. During that year you receive all the new versions we release.
• After that year, you keep using Cairn without limits with your version. If you want access to the versions released after your year of updates, you can renew the license. Renewing is optional: you only need it if you want the newest versions.

We do our best to maintain and improve Cairn, but we don't guarantee a specific update frequency nor that a specific feature will exist in the future.

5. Price, taxes and payment

Pro's price is shown on the site at the time of purchase. Payment is processed through Stripe. Depending on your country, taxes (such as VAT) may apply, which will be shown or calculated during checkout.

6. Refunds

We want you to buy with peace of mind. If Cairn isn't for you, write to us from the contact form within 14 days of purchase and we'll refund you. Since you can try all the features with the free plan before paying, we recommend doing that first.

7. Intellectual property

Cairn, its code, its brand and its website are the property of The No-Code Company OÜ and are protected by law. Your license gives you the right to use the software; it does not transfer ownership to you. The projects you create with Cairn are yours.

8. Warranties and liability

Cairn is provided "as is" and "as available". To the extent permitted by applicable law, we offer no warranty that the software is free of errors or fit for a particular purpose, and our total liability to you is limited to the amount you paid for the license. Nothing in these terms excludes liabilities that cannot be excluded by law, including the rights you have as a consumer.

9. Changes to the terms

We may update these terms; we'll reflect the date under "last updated". The terms applicable to your purchase are those in force at the time of buying.

10. Governing law

These terms are governed by the law of Estonia, without prejudice to the mandatory consumer-protection rules of your country of residence. For any matter, contact us first from the contact form: almost everything is sorted out by talking.
