What is FBReader?

Safety overview
Status: Safe
FBReader is a legitimate reading app for ebooks and documents. Access to local files is normal for its purpose, and cloud sync is an expected feature if you choose to use it across devices. If you store books through its online sync features, keep in mind that your library metadata, bookmarks, and reading positions may be transmitted to the service you enable. Use the app's sync options only if you want cross-device reading, and keep sensitive documents in local-only storage if you prefer not to upload them.
Recommendation: Keep FBReader if you use it to read ebooks on your Mac or sync reading across devices. Remove it if you no longer use it or prefer another reader, knowing that uninstalling it may leave your books untouched but can remove app-specific settings, local library data, and sync convenience.
