Matrix is amazing but even as a programmer I have no idea what their Security and Privacy page means. If it is meant for masses then average Joe should be able to understand it.
I found their Privacy Policy surprisingly approachable (https://matrix.org/legal/privacy-notice). Maybe because I've read through tons of policies before, but theirs seem to use very easy language, even for someone who's not a native English speaker.
Could not find any page who's title is just "Security".
I meant the User name>Settings>Security & Privacy page. It can be found when you click on the username. Verifying devices on new login, keeping the recovery key safe, etc. will be difficult for users.
Sounds like you're talking about a Matrix client, not Matrix itself. So I still don't know what you're talking about exactly, which client are you using?
