P7C4A

Personal utility

Encrypted recovery for selected files.

P7C4A is a personal backup utility that encrypts selected recovery data before placing it in the owner’s Google Drive.

How it works

  1. The owner selects files for recovery.
  2. Data is encrypted locally before upload.
  3. The owner keeps the recovery password separately.

Limited Drive access

The app uses Google’s drive.file permission for files it creates or that the owner explicitly grants. A pinned folder setting helps the utility locate its working area; it is an operational setting, not a Google folder-only security boundary.

Backup contents and original file names are encrypted locally. The folder name, encrypted object names, sizes, and upload metadata remain visible to Google Drive.
