resolve-backup is a private tool used only by its owner.
It accesses Google Drive only with the drive.file scope, which means it can see and change only the files it creates itself: database backup files in the owner's own Drive.
No data is collected, sold, or shared with third parties. Nothing is stored anywhere except the owner's own server and Google Drive.
Access can be revoked at any time at myaccount.google.com/permissions.
