Oh. I use a similar one called Ironvest. They also have masked cards to use. But they're virtual cards so I can't use them in meatspace.
I tried to sign up for privacy.com. They I send a digital copy of my photo ID to a 3rd party! I said no thanks. Ironvest is also not anonymous ofc. But they never demanded a copy of my ID. They confirmed me in other ways. I've had it a long time. I dunno if they would require it now for new signups or what. But I never had to.
I wouldn't even mind except nobodys shit is secure. I send ID to whatever identity resolver privacy.com uses, and only a matter of time till it leaks to every identity thief.
