Visible data ≠ hidden data.
Visible pixels and hidden file data are different things. Privacy work often means checking both what people can see and what the file still carries with it.

Useful to know
Four things worth knowing.
Privacy has two layers.
Blur can leave information recognisable, and removing metadata does not hide text, faces, notifications or locations visible inside the image itself.
Check the whole shareable copy.
Play the exported file from beginning to end and check picture, sound, crop, timing and orientation.
Export, do not overwrite.
Make a separate sharing copy. Keep the untouched original somewhere private instead of overwriting it.
