I signed in with Google but my books are gone

If you previously used email/password and then signed in with Google using the same email, your account should be linked automatically. If your data is missing, try signing out and signing back in with your original email/password method.

  • Check your spam/junk folder.
  • Make sure you’re entering the email you used to sign up.
  • If you signed up with Google, you don’t have a password — use Google Sign-In instead.

  • Make sure you’re signed in with the same account on both devices.
  • Pull to refresh (mobile) or reload the page (web).
  • Check your internet connection.
  • Verify your API key is correct in your e-reader settings.
  • Make sure the server URL is exactly: https://api.bookwormtracker.com/integrations/kosync
  • Check if the book is matched — unmatched books won’t update progress. See E-Reader Integration.
  • Clear your browser cache and reload (web).
  • Close and reopen the app (mobile).
  • Check if there’s an app update available (mobile).

Some books in the database don’t have cover images. This is a limitation of the book data sources. The book will still function normally without a cover.

  • Try shorter search terms (just the title or just the author’s last name).
  • Try searching by ISBN if you have it.
  • Some very new or self-published books may not be in the database yet.
