I had to sit on a waiting list for a few weeks to get invited to it about 1 year ago. I don’t know what that was all about but it seems they aren’t in a rush for more users.

Btw their numbers don’t work with Adobe, but I used Privacy for a Microsoft Office trial about 6 months ago and I got an email every time Microsoft attempted to charge me, which was approximately once/week before I just deleted that card.
