Common questions

My streak disappeared after reinstalling

Progress is tied to an anonymous account created on first launch, and deleting the app removes it from the device. Linking an Apple or Google account — which survives a reinstall and a new phone — is planned. Until then, updating the app is safe; deleting it is not.

Why don’t I see a percentile?

Because there is not enough data to compute one honestly yet. A percentile from an invented distribution is worse than no percentile, so it stays hidden until it is real.

How do I delete my data?

Settings → Account & data → Delete all data. It removes the account and everything on the servers, immediately and permanently. Reset progress is separate: it clears records and streak but keeps the account. See the privacy policy.

A theme is easier than another one, right?

No, and this is enforced rather than promised. Every theme keeps the same contrast between the stimulus and the background, so no theme makes the test easier — otherwise leaderboard rows would stop being comparable.
