Vanguard takes screenshots of your PC every time you play a game. Every time you play a game a function is called to screenshot your PC’s screen, in case Vanguard thinks you might have something suspicious, it screenshots your ENTIRE PC screen (all monitors).
Edit: Not trying to spread false info this was shared to me via a friend and there is other data to back up that this is real https://www.unknowncheats.me/forum/anti-cheat-bypass/634974-vanguard-taking-screenshot-pc.html

There should be laws against this everywhere (with other forms of data collection included). There’s no way preventing cheating is more important than the fundamental rights to security and privacy.
There is, this could have the potential to collect PII and its %100 they’re not storing this as encrypted data on their side. So it is %100 illegal to do, now if they’re fined for it is a different story.
Even if encrypted this doesn’t sound like something compatible with the GDPR.
