FlashCard Chinese — help, common questions, and how to reach us.
Need help with something not covered below?
We usually reply within a couple of days. Including your iOS version and app version helps us answer faster.
How do I create an account?
An account is optional. Open Settings → Account and tap Sign in with Apple. You can hide your real email address when you do — the App will only ever receive Apple's private relay address. Everything except cloud sync works without an account.
How do I delete my account?
Open Settings → Account → Delete Account and confirm. Deletion is immediate and permanent. It removes your account and all data synced to it — decks, cards, review history and settings — from our server in one step. There is no undo.
Deleting your account does not cancel a Pro subscription, because subscriptions are managed by Apple, not by us. To cancel, see below. If you would rather have us delete the account for you, email us at the address above.
I paid but Pro is not active.
Open Settings → Pro → Restore Purchases. Purchases are tied to your Apple ID, so make sure you are signed in to the same Apple ID you bought with. If it still does not unlock, email us with your App Store receipt.
How do I cancel my subscription?
Open the iOS Settings app → tap your name → Subscriptions → FlashCard Chinese → Cancel Subscription. You keep Pro until the end of the period you already paid for. Refunds are handled by Apple, not by us — request one at reportaproblem.apple.com.
I switched to a new device. Do I have to pay again?
No. Sign in with the same Apple ID and tap Restore Purchases. If you also sign in with Apple inside the App, your synced study data comes back too.
What does cloud sync actually sync?
Your decks, the flashcards in them, and your review history. It happens only while you are signed in. See the Privacy Policy for the full detail.
Can I use the App on two devices at once?
Yes. Sign in with Apple on both and they stay in sync. If the same card is reviewed on both while offline, the review history from both is kept and the schedule is recalculated from the combined history.
Is my data saved if I delete the App?
Only if you are signed in and have synced. Data that was only on the device is removed with the App. Signing in first is the safe way to keep your progress.
How do I export my cards?
Settings → Export. You can export all cards as JSON or a deck as CSV.
The camera will not recognise the text.
Try to fill the frame with the text, hold the device steady, and make sure the lighting is even. Recognition runs on your device and works best on clearly printed text rather than handwriting. You can always type the sentence in by hand instead — OCR just saves you the typing.
How do I change the speaking speed or voice?
Settings → Playback. Speed and voice are separate settings. If you hear nothing, check that the ringer switch is not on silent and that the volume is up.
Notifications are not arriving.
Check iOS Settings → Notifications → FlashCard Chinese and make sure they are allowed, then confirm your reminder time under Settings → Reminder in the App. Reminders are scheduled locally on your device.
