Privacy Policy

Who we are

Ibycus is an independent app that matches your photos with classical poetry. It is developed and maintained by a single developer. You can reach us at [email protected].

What data we collect

We collect no personal data. Specifically:

• Photos you take or select are processed locally on your device using on-device machine learning models. They are never uploaded to any server.
• Your poem history is stored locally in your app's private storage. It never leaves your device.
• We do not use analytics, tracking, or crash reporting services.
• We do not use advertising networks.
• We do not create user accounts or profiles.

Optional feedback

Ibycus includes an optional feedback feature: you can like or dislike a poem match. If you choose to send feedback, a brief anonymous signal (the reaction type and the matched poem's metadata) is sent to the developer to help improve matching quality. No personal information is included.

Optionally, you may also choose to attach the photo you used for matching. This only happens if you explicitly agree when prompted — the app asks once before sending any photo. The photo is seen only by the developer and is never shared with third parties.

Feedback sending is on by default but can be disabled at any time in Settings.

Third-party services

Ibycus uses Google ML Kit Image Labeling, which runs entirely on-device. No image data is sent to Google's servers as part of this process. You can read more about Google ML Kit's on-device processing at developers.google.com/ml-kit.

The app is distributed through Google Play. Google Play may collect usage and device data under their own privacy policy, which is separate from this one.

Permissions

Ibycus requests the following device permissions:

• Camera — to take photos for poem matching. Used only when you initiate it.
• Photo library — to select photos from your gallery. Used only when you initiate it.

No other permissions are requested.

Data retention

Since all data is stored locally on your device, you are in full control. You can delete individual history entries from within the app at any time. Uninstalling the app removes all stored data.

Children's privacy

Ibycus does not knowingly collect any information from anyone, including children. The app contains no user accounts, no data submission, and no network communication involving personal data.

Changes to this policy

If we make material changes to this policy, we will update the date at the top of this page. Since we collect no data, changes are unlikely to affect you in any meaningful way.
