This policy describes the current setup and intended operation of Home Finance Backup, a service for one owner using the owner's own Google account. It requests one Google permission, Google Drive 'drive.file', which lets the service see and change only files it created or files the owner opens or shares with it. After the owner approves, the service keeps Google authorization credentials (including a long-lived refresh credential) on its server and uses them to upload encrypted backup files to a folder in the owner's Google Drive and to read back its own backup files to check them. Backups are encrypted before upload; the decryption key is not kept on the service's server. Google user data is used only to provide this backup. It is not sold and not used for advertising. It is processed by Google (Drive), by the cloud services hosting the service (Cloudflare and Supabase), and, for maintenance or restoring a backup, by people or services the owner authorizes. Backup files stay in the owner's Drive until the owner deletes them; there is currently no automatic deletion. The owner can revoke access at any time in the Google Account permissions page and can delete the backup files in Drive. Google does not state how quickly revocation takes effect.
