Legion Server Backup is a personal tool used only by its owner. It uses Google OAuth to let the owner's Ubuntu server store encrypted backups in the owner's Google Drive. Its drive.file permission allows it to see, create, edit, and delete only files created or opened with the app. It does not request access to the rest of the owner's Drive.
Backup content is encrypted locally by restic before upload. Google stores the encrypted archive in the owner's Drive. The OAuth credential and backup encryption key are stored on systems controlled by the owner. This website has no forms or tracking scripts. Cloudflare hosts these pages and may process standard request and security logs under its privacy policy.
The owner controls how long backups are kept and can revoke Google access from Google Account settings. Revoking access stops future backups until the connection is restored; previously uploaded backup files remain in Drive until the owner deletes them.
