# What is the anonymous machine tag, and does it identify me?

It's a scrambled, one-way code that is unique to your Mac but can't be reversed to reveal anything about it. It doesn't contain your Mac's name, serial number or network address.

It exists for two practical reasons: to tie a licence or free trial to the Mac it was started on (so a trial can't be restarted endlessly by reinstalling), and to count machines in the anonymous activity report without knowing whose they are.

On its own it isn't linked to your name or email. When you activate a paid licence, your purchase is associated with that tag so the licence works on this Mac — that's the only place the two meet.
