The Service
Cairn is a local-first daily logging app. All data is stored on your device and optionally synced via iCloud.

You own your data. Cairn stores everything locally on your device. We do not have access to your logs, tokens, or categories. If you use iCloud sync, your data is stored in your private iCloud database managed by Apple.
Acceptable Use
You agree not to:
- Reverse engineer or modify the app
- Use the app for any unlawful purpose
- Attempt to access systems or data you’re not authorized to access
Disclaimer of Warranties
Cairn is provided “as is” without warranties of any kind. We do not guarantee that:
- The app will be available without interruption
- Data will not be lost
- iCloud sync will always be available
We recommend using iCloud sync or periodic CSV exports to protect against data loss.
Limitation of Liability
To the maximum extent permitted by law, Cairn and its developers shall not be liable for any damages arising from use of the app.
Changes to Terms
We may update these terms at any time. Continued use of the app after changes constitutes acceptance.
