A question is wrong, or my answer was right
Tap “Report a wrong question” in Settings › Legal & support, or on the correction sheet. The report carries the question id, your answer and your level — nothing else. Confirmed errors are fixed in the next content update and the miss is removed from your history.
I lost my streak or levels after changing phone
Without an account, training lives only on the old device. With Sign in with Apple, open Settings › Account on the new phone and sign in with the same Apple ID — levels, streak and review dates come back within a few seconds.
Restore a Pro purchase
Settings › Account › Restore purchase, on the same Apple ID that bought it. Family Sharing is supported for the yearly plan.
Cancel a subscription
Subscriptions are managed by Apple: iOS Settings › your name › Subscriptions › Reckon. Cancelling keeps Pro until the end of the paid period, then leaves Number Fluency working as before.
Reminders aren't arriving
If you declined the permission, Settings › Reminders shows a row that opens iOS Settings. Reckon sends at most three notifications a week and none on a rest day, so silence can also be by design.
Delete my data
Settings › Account › Privacy › Delete account removes the server copy within 30 days. Deleting the app removes the on-device copy immediately.
