Do I need an account?

No. You can learn and play without one, and your progress stays on your device. Signing in with Apple or Google saves your progress to your account, so it comes back on a new phone or after reinstalling the app.

My progress didn't come back

Make sure you signed in with the same Apple or Google account you used before. Lessons finished while offline are saved on your device and uploaded the next time you're online and signed in.

How does the streak work?

Finish at least one lesson or review each day to keep your streak. Days follow your phone's time zone. A week-long streak earns a streak freeze, which covers one missed day.

What is Review?

The Review tab quizzes you on openings from lessons you've finished, starting with the ones you're most likely to forget. Reviews earn XP and count toward your streak.

Changing your username or deleting your account
