Privacy Policy

Last updated: May 18, 2026

This Privacy Policy describes how the APA Learn mobile application ("APA Learn", "the app", "we", "us") handles information when you use it. APA Learn is an educational app built by Michel Adelino to teach classic algorithmic problems (Knapsack, TSP and others) through interactive gameplay.

1. Information we do not collect

APA Learn does not collect, store, transmit, or share any personal or sensitive user data. Specifically, the app does not collect:

  • Personal identifiers (name, email, phone number)
  • Account credentials
  • Contacts, calendar, SMS or call logs
  • Photos, videos or files
  • Precise or approximate location
  • Microphone or camera input
  • Health or fitness data
  • Financial or payment information

2. Data stored on your device

Some preferences and progress are stored locally on your device only, using the operating system's standard storage APIs. This includes:

  • Your selected language (English or Portuguese)
  • Game progress and difficulty selection
  • App settings

This information never leaves your device and is removed when you uninstall the app.

3. Network access

APA Learn uses the network only to check for new versions of the app on the Google Play Store (via the Upgrader library). No personal information is sent in this request.

4. Third-party services

APA Learn does not integrate any third-party analytics, advertising, tracking, or crash-reporting SDKs.

5. Children's privacy

The app is suitable for all ages and does not knowingly collect any data from children or any other user.

6. Permissions

APA Learn requests only the minimum permissions needed to run, such as internet access for store version checks. It does not request access to sensitive permissions like location, camera, microphone, contacts, or storage.

7. Changes to this policy

We may update this Privacy Policy from time to time. Any changes will be reflected on this page with a new "Last updated" date.
