It doesn’t delete your stuff it just doesn’t save your history and cookies as a save browser should do. For me that little inconvenience is fine because I get a big privacy benefit out of it IMO.

Me too lol, why cant I see other replies tho?

You can set exceptions to the cookie deletion in the security settings. I personally have everything I use frequently (invidious and stuff) to keep the login cookies. Or you can just completely disable that feature.
