A private application.
This is a private data collection system operated for the account owner's own use. It is not a public service: there are no user accounts and no sign-up.
The application uses the Google Drive API for a single purpose: to upload and verify its own data files into the account owner's Google Drive, as a backup. It does not access, read, or transmit Google data belonging to anyone else, and it shares no data with third parties. This use complies with the Google API Services User Data Policy, including the Limited Use requirements.
