Privacy Policy
1. Summary
Aegle is a personal nutrition and outcome diary that runs entirely on your device. Aegle does not create an account, does not connect to the internet, does not transmit your data to the developer or to any third party, and does not use advertising, analytics, or crash-reporting SDKs.
The release build of Aegle does not include the Android
INTERNET permission, so it is technically incapable of
sending data off the device.
2. What data Aegle handles
All of the following is created and stored only on your device:
-
Diary events you log:
- Nutrition events (food and ingredient items, optional product groupings, timestamps).
- Outcome events (severity values for symptoms or wellbeing measures you select, timestamps).
- Custom items and outcomes you add or edit.
- Favourites and filter preferences.
- Oracle analysis results (statistical model outputs derived from your diary, recomputed on demand on your device).
- Application logs (technical events such as startup status, errors, and warnings) stored in a local file.
Some of this data is health-related and may be considered sensitive.
3. Where the data is stored
- Data is written to encrypted Hive databases inside Aegle’s private app storage (
AES-256-GCM). - The encryption key is generated on first launch and held in the Android Keystore via
flutter_secure_storage. - Auto-backup to the cloud is disabled. Uninstalling Aegle deletes all data; there is no remote copy.
4. Sharing
Aegle does not share your data with the developer, with advertisers, with analytics providers, or with any other third party.
The app provides a single explicit, user-initiated action that can move data off your device:
- Export Database. When you tap Export, Aegle writes an unencrypted JSON file containing your full diary and hands it to the operating system’s share sheet so you can save or send it to a destination of your choice. Once the file leaves Aegle (for example to a cloud-drive app, email, or messaging app), responsibility for protecting it is yours and is governed by the privacy policy of the destination service.
5. Permissions
The release build requests no runtime permissions and declares no internet permission. The app may request access to the system file picker only when you tap Import Database, and only for the file you select.
6. Children
Aegle is not directed at children under 13 (or under 16 in jurisdictions that require a higher age of consent) and does not knowingly collect data from them.
7. Your rights
Because all data lives on your device, you remain in direct control:
- Access: view all entries in the Diary, Organizer, and Oracle screens.
- Portability: export everything as JSON via Export Database.
- Erasure: use Clear Database in the side drawer, or uninstall the app, to delete all data.
If you believe this policy has been violated, contact the developer at the address above.
8. Medical disclaimer
Aegle is a personal tracking tool. It is not a medical device and does not provide medical advice, diagnosis, or treatment. Patterns and predictions shown by the Oracle are statistical observations only. Always consult a qualified healthcare professional before making changes to your diet or health routine.
9. Changes
If this policy changes, the updated version will be published at the same URL with a new effective date. Material changes will also be announced in the app’s About screen.
