Account, sign-in or sync
You can play in Guest Mode or link Apple/Google from Profile → Account. If sync appears stuck, confirm connectivity, reopen the app and avoid deleting local data until support replies.
Delete or export my data
Open Profile → Account in LinguaCase. Export creates a readable local summary. Delete removes local data; for a linked account it also requests removal of the owned Firebase user tree, Storage files and authentication identity after reauthentication.
Microphone or speech does not work
Typed input remains available. Review Microphone and Speech Recognition permissions in iOS Settings → LinguaCase. Raw microphone recordings are not stored by LinguaCase.
Paid download or refund
LinguaCase is a one-time paid App Store download with no subscription or in-app upgrade. Apple handles purchase history, billing and refund requests.
Accessibility
LinguaCase supports VoiceOver, Dynamic Type and iPad layouts. Include the screen name, device model and the accessibility setting involved in your request.
Support inside the app
Open Profile → Help & Legal → Support to review help and share privacy-safe diagnostics. For data deletion, use Profile → Account → Delete account and data. Do not include passwords or authentication codes in anything you share.
