Frequently asked

Is my data private?

Completely. LockMark runs entirely on your device. Your documents, recipients, passwords, and logs never leave your computer — there are no servers and no accounts. See our Privacy Policy.

Which platforms are supported?

macOS today. A Windows build is coming soon. Pro and Enterprise tiers are coming soon as well.

What file types can I mark?

PDF documents today. Word, slides, and image folders are on the roadmap.

I lost a copy's password — can you recover it?

We can't, and that's by design: nothing is stored off your device, so there's no copy of your passwords anywhere else. Keep the tracking log LockMark generates in a safe place — it holds every copy's password.

How does identifying a copy work?

In LockMark Lite, drop a PDF back into the app and it reads the invisible per-copy identifier, then names the recipient the copy was issued to. Matching a photo or screenshot is part of LockMark Pro (coming soon). Attribution is probabilistic; see the Terms.
