1. Information we collect

· Your course progress (lessons marked as completed and quiz results) is stored only on your device and is not sent to our servers.

2. Advertising
· The app shows third-party ads (Meta Audience Network and Unity Ads). These companies may collect technical information such as your device's advertising ID, device model and OS version, IP address, approximate location derived from the IP address, and ad interactions, in order to serve and measure ads.
· You can reset or delete your advertising ID and opt out of personalized ads in your device's Google settings.

3. Third-party services
· The app is built with the AppCreator24 platform, which processes the technical data needed for the app to work, send notifications and produce aggregated usage statistics.
· Course manuals are displayed from Google Drive; when you open them, Google's privacy policy applies: https://policies.google.com/privacy
· Some sections open external websites, which are governed by their own privacy policies.

4. How we use information
· We use information only to operate the app, show ads and improve the content. We do not sell personal data.

5. Children
· The app is not directed at children under 13, and we do not knowingly collect data from children.

6. Data retention and deletion
