Leetcode Explorer (“the app”) is an offline study aid published by wihoho on Google Play.

Data collection

The app does not collect, transmit, share or sell any personal or sensitive user data.

  • The app has no accounts, sign-in, analytics, advertising, crash reporting or third-party SDKs that send data.
  • The Android build does not request the INTERNET permission, so it cannot connect to any server.
  • All problems and solutions are bundled inside the app.

Data stored on your device

If you bookmark problems, the list of bookmarked problem numbers is saved in the app’s private storage on your device only. It is never uploaded, and it is deleted when you uninstall the app or clear its storage. The app opts out of Android cloud backup.

Children

The app does not knowingly collect any information from anyone, including children.

Changes
