Privacy

Enrolling stores a set of mathematical descriptors of your face, not photographs. They live in ~/Library/Application Support/MacID, in a directory only your account can read. Deleting your face data in the app removes them.

Frames are read at the lock screen, compared on the spot, and discarded. No frame is written to disk, and none is kept after the comparison. Whether the camera turns on when the screen wakes or only when you press Return is your choice, in Settings.

Recognition runs through Apple's Vision framework on your own machine. There is no account, no sign-in, no server that sees your face, and no model downloaded at runtime.

MacID sends nothing about you. No analytics, no crash reports, no usage counts. Its only network request is a daily check of macid.akshith.io for updates, which you can turn off in its settings.

This site counts visits with Vercel Web Analytics, which uses no cookies and keeps no personal data: just the page visited and the site that linked to it. Downloading MacID is an ordinary web request, and Vercel, who host it, keep the operational logs any web server keeps.

MacID is open source. Every claim above is something you can verify in the repository.
