A private tool used by one person. It copies files from his own computer into his own Google Drive, so his assistants can read them there. It is not offered to anyone else.
The tool asks Google only for access to the files it creates itself (the drive.file scope). It cannot see any other file in the Drive. It collects nothing about anyone, keeps no analytics, and shares no data with any third party. The only data it handles are the owner's own files, sent from his computer straight to his own Google Drive.
For the owner's personal use only.
