BookKind account
Delete your account
You can delete your BookKind account yourself, in a minute, from the app or the web app. This page explains what goes, what to do first, and how to ask us if you cannot sign in.
In the app
- Open BookKind on your phone, or sign in at bookkind.wattkind.ai.
- Open Settings (the gear at the top of the Reading screen) and scroll to Your data.
- If you want a copy first, tap Export library (CSV) or Export everything (JSON).
- Tap Delete my account, then Delete everything to confirm.
That is it. You are signed out and the account is gone straight away.
What is deleted
Your library, covers, reading log, goals and achievements, Librarian and AI Book Club chats, the Librarian's notes about your taste, your preferences, your sessions and your account record. Your sign-in with our sign-in provider is deleted as well, and if you used Sign in with Apple, the token Apple gave the app is revoked. Nothing is kept except the server's access logs, which hold request paths and IP addresses for 30 days and then go, and anonymous AI usage records without any conversation text, kept 13 months for cost tracking.
Subscriptions
Deleting your account does not cancel a BookKind Librarian subscription, because the subscription is with Apple or Google, not with us. Cancel it in your iPhone's Settings → Apple Account → Subscriptions, or in Google Play → Payments and subscriptions → Subscriptions, before or after deleting.
If you cannot sign in
Email support@wattkind.ai from the address you signed up with, or tell us which Apple ID or Google account you used, and we will delete the account within 30 days and confirm by email.
Questions? Email support@wattkind.ai — it comes straight to us, and we reply ourselves. The full privacy policy has the rest.
