See what leaves with a file before you send it

An offline check of everything a file carries that you did not mean to send: tracked changes with the deleted text still readable, review comments, worksheets hidden at the veryHidden level, attachments inside a PDF, GPS coordinates in photos, and validated card and IBAN numbers.

What it does

Reads the file formats directly - no network access at any point, so it is safe on material that must not leave the machine.
Validates card and IBAN numbers rather than matching digit patterns, which is the difference between a finding and noise.
Reports what it found and where, and changes nothing.

How it is proved

38 tests across office documents, PDFs and images.
