My religion is fundamentally based on the idea of gay catgirl supremacy and worship. Service to the catgirls may come in the form of headpats and sacrifices are accepted in the form of baked juicy chicken :3

You could literally read the GraphineOS documentation whenever you want where it clearly outlines how their hardening works, what security systems they have in place, and how their encryption works. I will warn you its incredibly technical, of course you wouldn’t know that because people like you who cant bother to even look at the website (https://www.grapheneos.org/features) wouldn’t know what any of it acturally means.

Tldr: for people who dont understand technical terminology they can trust the project, for people who do they can literally just read the documentation
