Learn SQL ("the app") is developed and published by an independent developer. This policy explains what data the app collects and how it is used. Learn SQL does not require an account and does not ask you for your name, email, or any other personal identifiers.
Local, on-device data. Your lesson progress, bookmarks, search history, and app preferences (such as theme and reminder settings) are stored only on your device. This data is not sent to us and is deleted if you uninstall the app.
Analytics and crash data. The app uses Firebase Analytics and Firebase Crashlytics (both provided by Google) to understand feature usage (e.g. which lessons are opened or completed, searches performed, screens viewed) and to diagnose crashes. This data is associated with an anonymous device/installation identifier, not your name or email.
Advertising. The app displays banner ads served by Google AdMob. AdMob may collect device identifiers and usage data to serve and measure ads, and may use this data for ad personalization in accordance with Google's own privacy policy, linked above. You can review and adjust Google's ad personalization settings at adssettings.google.com.
We do not sell your data, and we do not use it for any purpose beyond what is described above.
Learn SQL is not directed at children under 13, and we do not knowingly collect personal information from children.
You can disable analytics collection at the OS level (Android Settings → Apps → Learn SQL → Permissions/Data), or reset your advertising ID / opt out of ad personalization via your device's ad settings. Uninstalling the app removes all locally stored data.
We may update this policy from time to time. Material changes will be reflected by updating the "Last updated" date above.
