This page explains how to delete your BookReader account, how to delete only your synced data while keeping the account, exactly what each option removes, and what happens if you can no longer open the app.
You may not have an account at all. BookReader works fully offline and signing in is optional. If you never signed in with Google, there is no account and nothing stored on our servers — uninstalling the app removes everything.
1. Delete your account
This deletes your account, your Google sign-in for BookReader, and everything stored on the account. It cannot be undone.
- Open the BookReader app.
- Go to the Profile tab.
- Under the account card, tap Delete account.
- Read the confirmation and tap Delete.
The deletion happens immediately. You are signed out on that device, and the account is gone on every other device you used it on. Signing in again later starts a completely new, empty account.
2. Delete only your synced data
If you want to remove the copy stored on our servers but keep your account and sign-in, use this instead.
- Open the BookReader app.
- Go to the Profile tab.
- Under the account card, tap Delete cloud data.
- Read the confirmation and tap Delete.
Your account, sign-in and app settings stay. The synced library, reading progress, highlights, notes, saved words, reading history and any backed-up book files are erased, on every device. Cloud sync is then switched off on your device until you turn it back on with the Cloud sync switch on the same screen.
3. What is deleted, and what is kept
| Data | Delete account | Delete cloud data |
|---|---|---|
| Account record (name, email, profile photo, registered devices) | Deleted | Kept |
| Google sign-in for BookReader | Deleted | Kept |
| Synced library (book titles, authors, formats) | Deleted | Deleted |
| Reading progress and reading history | Deleted | Deleted |
| Highlights, bookmarks and notes | Deleted | Deleted |
| Saved words (your dictionary) | Deleted | Deleted |
| Book files you backed up to the cloud | Deleted | Deleted |
| Reader settings (font, theme, daily goal, reminders) | Deleted | Kept |
| Books and reading data stored on your own device | Kept | Kept |
Books on your device are never touched. Neither option deletes the PDF, EPUB, Word or text files on your phone — they are your files. To remove those, delete them from your device, or uninstall the app to clear the reading data it stored locally.
Retained after deletion
- AI usage records — a record of AI requests made on the account is kept as an accounting ledger. It contains usage amounts, not your documents or their contents.
- Analytics and crash reports — retained for the periods set by Firebase, typically up to 14 months for analytics and 90 days for crash reports. These are not linked to your account once it is deleted.
- Backup copies — routine system backups may hold deleted data for a short period before being overwritten.
4. If you cannot open the app
If you have uninstalled BookReader, lost the device, or cannot sign in, email us and we will delete the account for you:
Send the request from the email address you signed in with, so we can identify the account, and say whether you want the whole account deleted or only the synced data. We action requests within 30 days.
Using an older version of the app? The in-app options above are in the Profile tab of the current version. If you do not see them, update BookReader from Google Play, or email us using the address above.
