Common questions
Audio won’t play.
Check that the card is not muted, your device volume is on, and the app has finished loading its audio catalog.
My ad-removal purchase is missing.
Open Flashcard Settings and choose Manage Ads, then Restore purchases. Purchases must come through the official App Store or Google Play version.
How do I delete my data?
Study preferences, saved cards, and progress live on your device. Clear the app’s storage or uninstall the app to remove them. For support correspondence, email a deletion request.
