Q: I forgot to back up before reinstalling. Can I recover my data? No. By design, Whisker has no server and no copy of your records. The encrypted database lives only on your device. Always create a backup before deleting the app or moving to a new phone — Settings → Backup.
Q: How does the 12-word backup work? We generate a BIP39 mnemonic phrase (12 English words). The phrase derives an AES-256 key that encrypts your backup file. To restore, enter the same 12 words on a new device. Write them down on paper and store them somewhere safe. We cannot recover them for you.
Q: Why is my Apple Health step count not showing up?
Q: I scanned a lab report but no values were extracted.
Q: I subscribed but Premium features are still locked.
Q: How do I cancel my subscription? On iOS: Settings → [your name] → Subscriptions → Whisker → Cancel. Cancellation takes effect at the end of the current paid period.
Q: Does Whisker work without internet? Yes. The only feature that needs the network is the in-app purchase flow, and even that can fall back to “Restore Purchases” later.
