You may use Cairn only in compliance with applicable law and these terms. Cairn is intended to support personal wellness habits and reflection, not to diagnose, treat, cure, or prevent any medical condition.

You are responsible for how you use the app, including whether fasting is appropriate for you. If you have any medical concerns, consult a qualified healthcare professional before relying on Cairn.

Some features may require a paid subscription such as Bloom. Subscription billing, renewals, and cancellations are handled by the platform you purchase through and are also subject to that platform's terms.

We may change, suspend, or discontinue features at any time, including during the current pre-release period.

You may not misuse Cairn, interfere with its operation, attempt unauthorized access, reverse engineer protected parts of the service where prohibited, or use the service in a way that harms others.

All Cairn branding, software, visuals, and related content remain the property of Cairn and its licensors unless stated otherwise.

Cairn is provided on an 'as is' and 'as available' basis without warranties of any kind to the extent allowed by law.

To the fullest extent permitted by law, Cairn will not be liable for indirect, incidental, special, consequential, or punitive damages, or for loss of data, profits, or goodwill arising from your use of the service.

We may update these terms from time to time. Continued use of Cairn after an update means you accept the revised terms.
