Common questions

Do I need an internet connection?

No. The service logbook, reminders, document vault, and the entire offline fault-code & warning-light dictionary all work with no signal at all. Only “Explain simply” (AI) and VIN auto-fill need a connection, and both degrade gracefully without one.

I cancelled Pro — what happens to my data?

Nothing. Your logbook, reminders and documents stay exactly as they are; the app simply returns to the free-tier limits (one vehicle, one stored document) going forward. Nothing is deleted.

How do I cancel or restore a subscription?

Subscriptions are billed by Apple or Google, not by us — manage, cancel, or restore them from your Apple ID (Settings → your name → Subscriptions) or Google Play (Play Store → Menu → Payments & subscriptions).

Can I get my data back if I lose my phone?

Only from your own device backup (iCloud / Google device backup) — Watabook has no account and no server copy, by design (see our Privacy Policy). Exporting a CSV backup from time to time is a good habit.

Is the AI explanation a real diagnosis?

No — it's general information to help you understand a fault code, never a substitute for a mechanic's inspection. See our Terms, §6.
