Security & privacy on this instance / lemmy as a whole?

I've just come from the reddit exodus and I'm looking around for some documentation or info on the privacy & security on infosec.pub and/or lemmy as a platform - how our logins are stored and whether data is accessible by developers / other parties.

Does anyone know where I can find more information on this? (Or if not could you shed some light)

This platform seems incredibly promising and I'm sick of reddit's ways now, but i want to read up before I fully commit. Many thanks!

(Edit - sorry if this isn't an appropriate place for this by the way, just seemed a sensible community to put it in!)
