Privacy Policy
Effective date: June 17, 2026
Tesseract is committed to protecting your privacy. This Privacy Policy explains how the app handles your information when you use it.
1. Information We Collect
Tesseract does not collect any personal information or usage data on our servers. Your diary entries are stored on your device.
2. On-Device AI
Speech-to-text for voice entries runs entirely on your device using Apple's on-device Speech framework. Your audio is transcribed locally and is never sent to us or any cloud service.
3. iCloud Sync (Optional)
If you enable iCloud Sync in Settings, your diary entries are synced through your own private Apple iCloud account so they stay available across your devices. This data is stored in your personal iCloud account, governed by Apple's Privacy Policy; we (the developer) cannot access it and never receive it on our servers. iCloud Sync is off until you turn it on.
4. Advertising & Analytics
We do not use any third-party advertising, analytics, or crash-reporting services. The app does not use the Advertising Identifier (IDFA) and does not track you across other apps or websites.
5. App Information Requests
The app may download a public list of our other apps and their icons from our website. These requests send no personal information about you.
6. Data Security
We are committed to protecting any data the app handles. Please be aware, however, that no method of electronic storage or transmission can be guaranteed to be perfectly secure.
7. Changes to This Privacy Policy
We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new policy on this page, and changes are effective once posted. You are advised to review this page periodically.
