Lingoop Yakgwa — Delete your data

App: Lingoop Yakgwa (Android) · Developer: AiDEX LAB · Updated October 19, 2026

The short version

1. Erase your data inside the app (recommended)

  1. Open Lingoop Yakgwa and go to Settings (bottom right).
  2. Tap Erase my progress and confirm.

This deletes, immediately and on your phone: all studied words, review boxes and dates, your streak, daily round counts, saved rounds and settings. It also resets the random app-instance identifier used by app statistics, so earlier statistics can no longer be linked to your phone. Deleting the app has the same effect on the data stored on your phone.

2. Request deletion by email

If you want us to help remove data held by the services the app uses, write to lingoop.cs@gmail.com with the subject "Lingoop Yakgwa data deletion request". Tell us roughly when you used the app; you do not need to send any personal information. We reply within 14 days and confirm what was done.

3. What is deleted, what is kept, and for how long
