If I cancel, will I lose my progress?

No. Cancelling your subscription does not delete absolutely anything. Your account will still exist with all your completed levels, your speed, your stats, your achievements, and your streak. The only thing that changes is what you have access to: you go back to the free plan, with levels 1 to 7.

What is kept

• All the levels you have completed remain marked as completed.
• Your stats and your speed and accuracy history.
• Your achievements and your best streak.
• Your account profiles and their data, even if they stop being accessible if they exceed the new plan.

If you subscribe again later, you get everything back exactly as you left it. You don’t have to start from scratch or “recover” anything: it’s still there.

Deleting your account does delete your data, but that is a different thing and must be requested explicitly.
