Cairn is a local-first app. Your data stays on your device. This policy explains how that works.
Information We Collect
We don’t.
Cairn does not require an account. There is no login, no server, and no data sent to us. All of your logs, tokens, and categories are stored locally on your device using Apple’s SwiftData framework.
iCloud Sync (Optional)
If you have iCloud enabled, Cairn can sync your data across your Apple devices using CloudKit. This sync is:
- Handled entirely by Apple’s infrastructure
- Stored in your private iCloud database
- Not accessible to us
See Apple’s iCloud Privacy Overview for details on how Apple handles iCloud data.
Analytics
Cairn does not collect analytics, crash reports, or usage data.
Third-Party Services
Cairn does not use any third-party services. The only external service involved is Apple’s CloudKit, and only if you have iCloud enabled on your device.
Data Sharing
We do not:
- Collect your data
- Sell your data
- Share data with third parties
- Display advertising
Your logs never leave your device (or your private iCloud account, if sync is enabled).
Your Rights
Your data is yours. You can:
- Export your logs as CSV at any time from the app
- Delete the app to remove all local data
- Manage or delete iCloud data through your device’s iCloud settings
