Privacy Policy

Annidiem · Last updated: September 13, 2026

Annidiem respects your privacy. In one sentence: this app collects no data — everything stays on your device and in your own private iCloud database.

How your information is handled

  1. No account is required. We do not collect, store, or upload any personally identifying information.
  2. Everything you create — dates, categories, and notes — is stored only on your device and in your own private iCloud database (CloudKit Private Database). The developer cannot access it.
  3. iCloud sync is optional: it uses the connection of your own iCloud account. Without an iCloud sign-in, or while offline, the app runs entirely on your device and every feature still works.
  4. Calendar access (optional) is used only for the import you start yourself. Only the items you select are read, and the whole process happens on your device.
  5. Notification access (optional) is used only for the reminders you turn on for a date.
  6. Face ID / Touch ID (optional) is used only to unlock the app locally. Biometric data is handled by the system Secure Enclave; the app cannot read it and never transmits it.
  7. AI greetings are generated on-device by Apple Intelligence (Foundation Models). They are fully offline and make no network requests.
  8. This app contains no third-party analytics, advertising, or tracking SDKs.
  9. Exported backups (JSON / .ics) are saved wherever you choose; their security is up to you and the storage service you pick.

Children's Privacy

The app collects no user data, so it also collects no personal information from children.
