Common questions
Do I need an account?
No. The app has no accounts and no sign-in. Everything you do is saved on your phone.
How do I delete my data?
Open the app, go to Profile, scroll to Reset all my data and confirm. This permanently clears your name, photo, scores and practice history from your device. It cannot be undone. Deleting the app also removes it.
How do I cancel or manage my subscription?
Subscriptions are billed by Apple. On your iPhone open Settings, tap your name, then Subscriptions, choose Digital SAT Math and tap Cancel Subscription. Deleting the app or your data does not cancel a subscription. For refunds, visit reportaproblem.apple.com – Apple decides refund requests.
I changed phone. How do I get my subscription back?
Install the app, open the subscription screen and tap Restore purchases. Use the same Apple ID that made the purchase.
I found a mistake in a question or answer.
Thank you – please email us the test name or number and the question number, and what looks wrong. We check every report.
Is my progress saved between devices?
Scores, times and answers are stored on your device. They are not synced between devices, and they are removed if you delete the app.
