Data Deletion

Last updated: October 15, 2026

This page explains how to delete data associated with the Nonogram app ("the App").

1. Local App Data

The App stores your puzzles in progress, solved pictures and best times, daily puzzle records and streaks, hint usage, and settings only on your device - the data never leaves your device in the first place. You are always in full control of it:

• Erase everything from within the App via Settings > Data > Reset all data. This removes saved puzzles, solved pictures, and records, and restores all settings to their defaults.
• Clear all App data at once via your device's Settings > Apps > Nonogram > Storage > Clear data.
• Remove everything permanently by uninstalling the App.

2. Advertising ID

Google AdMob serves ads within the App on our behalf and may use your device's advertising ID to do so. You can reset or delete this identifier independently, at any time, from your device's Settings > Privacy > Ads.

3. Crash Reports

If the App crashes, a technical crash report is sent to Firebase Crashlytics (Google). It contains no name, email address, or puzzle content, and is kept by Firebase for a limited time (90 days) before being deleted automatically.

4. Requesting Deletion From Us

Because the App does not send your personal data to our own servers, there is normally nothing on our side to delete. If you believe we hold any information about you and would like it removed, contact us with your device model and approximate date of use, and we will look into it and respond within 30 days.
