Privacy review before sharing

Create a reviewed derivative for the recipient instead of exposing private originals.

Android privacy-mask editor with a black rectangle selected by a yellow numbered outline over a fictional label.
Editor view, not the final shared copy. The selected mask was separately checked in recipient preview without the yellow overlay.

Steps

  1. Use Hide private information to draw black rectangles over sensitive details in image material.
  2. Review labels, scene descriptions, source names, choices, transcripts, captions, and audio separately. A visual mask does not inspect them.
  3. For moving video, play the entire rendered preview and make sure sensitive details remain covered in every frame.
  4. Open Preview recipient copy and traverse every route with the exact material the recipient will receive.
  5. Confirm I checked the recipient preview and that you have the right to share the material before making a file.

What to expect

The shareable practice uses reviewed derivatives. Private originals, edit history, personal notes, progress, and app settings are excluded.

If it does not work

Keep in mind

Masking reduces visible exposure but is not a guarantee that a file contains no personal or sensitive information. In the example image, the yellow numbered outline belongs to the editor and is not part of the recipient derivative.
