Support – Mathster

I paid to remove ads but still see them.
Open Settings → Restore purchases while signed in to the Google account that made the purchase. Rewarded videos are optional and still available by choice; banners and interstitials should be gone. If they return, email us with the Google Play order number (starts with GPA.).

My old high scores are missing after the update.
The new version reads scores from the previous Mathster on first launch. If you reinstalled instead of updating, the old data was removed by Android and cannot be recovered. If you updated and still see nothing, email us the app version; we will investigate.

How do I change difficulty or the answer input?
Tap the difficulty on the home screen (Easy, Medium, Hard; Expert with Pro). Settings → Answer input lets you choose tap options or the keypad.

How do I cancel Pro?
Google Play app → your profile → Payments & subscriptions → Subscriptions → Mathster → Cancel. Pro stays active until the end of the paid period.

How do I change my ad consent (EEA/UK)?
Settings → Privacy options reopens the consent form at any time.

Where is my data stored?
Only on your device. There is no account. See the privacy policy.

How do I delete my data?
Uninstall the app. All game data is removed. Your advertising ID is managed in Android settings.
