YELLN Server Backup is a private tool operated by the YELLN owner for backup and recovery of the owner's server. It is not a public service.

Google Drive access

The app requests only the drive.file permission. It uses that permission to create and retrieve its backup files in the owner's personal Google Drive. It does not request access to unrelated Drive files.

Backup data

The backup process encrypts server backup files before uploading them to Google Drive. Google stores the encrypted files and the storage metadata needed to operate Drive. The owner controls which server data is included in backups and how long backup files are retained.

Credentials and sharing

Authorization tokens and backup configuration are kept on owner-controlled computers for scheduled backup and recovery. The app does not use Google user data for advertising, analytics, or sale. It does not share Google user data with other users.

Owner controls

The owner can revoke the app's Drive access in Google Account settings. Revocation stops future access by the app; it does not automatically delete files already stored in Drive. The owner can remove those files in Drive.
