Purchases
Open Me → Store → Restore Purchases after reinstalling or changing devices. Manage subscriptions from App Store account settings. Apple handles billing and refund requests.
Microphone and reminders
Both permissions are optional. Review or change them in iOS Settings → DragonSpeak Mandarin. Speaking recordings remain on your device.
Delete your data
Open Me → Settings → Delete Learning Data to reset on-device progress, preferences, local entitlement evidence and app-owned reminders.
If you have bought or restored content, open Me → Settings → Delete Billing Account & Server Data to delete the app’s anonymous Firebase billing account and developer-held records linked to it. This does not cancel an Apple subscription or delete Apple’s records. See the privacy choices page for details.
