Common questions

How do I unlock all training modes?
Tap the gear icon (top right) and choose any mode marked “+”. You can subscribe to dadodeca+ monthly or make a one-time Lifetime purchase. Both unlock every training mode, the random shuffle, and all future modes.

How do I restore a previous purchase?
Open the dadodeca+ screen (gear icon → any “+” mode) and tap Restore Purchases. Make sure you're signed in with the same Apple Account you originally purchased with.

How do I cancel the monthly subscription?
Subscriptions are managed by Apple: open Settings → your name → Subscriptions on your device, choose dadodeca+, and tap Cancel. You keep access until the end of the paid period.

The app plays no sound.
Check the volume rocker and make sure another app isn't holding the audio route. dadodeca deliberately plays through the ring/silent switch, like a music app. If sound is still missing, force-quit the app and reopen it — and tell us if it recurs.

Where is the privacy policy?
