Well I'm not the most technical but on SimpleX you have no user ID's, routing through TOR and running your own servers among many other features (like the one that adds a radom delay to measages)
Oh that's very cool, I didn't know that. Although I think it isn't the most useful for me since I don't have lockscreen notifications and I have all my apps on the home screen
People in the comments already have "Avoid Gecko-based browsers like Firefox as they’re currently much more vulnerable to exploitation and inherently add a huge amount of attack surface. Gecko doesn’t have a WebView implementation (GeckoView is not a WebView implementation), so it has to be used alongside the Chromium-based WebView rather than instead of Chromium, which means having the remote attack surface of two separate browser engines instead of only one. Firefox / Gecko also bypass or cripple a fair bit of the upstream and GrapheneOS hardening work for apps. Worst of all, Firefox does not have internal sandboxing on Android."
I mean Gecko based browsers are actively recommended against on mobile. Chromium based browsers are recommended. Also I use mullvadVPN DNS based ad blocking, and I also have Brave that has built in ad blocking. Do yourself a favor and ditch adblock in favor of Ublock origin
Cromite, but I have switched to brave since, it has better fingerprinting protection, more updates, better security and better sandboxing and isolation. At least that's what Deepseek R1 with websearch has to say
If you have the budget, on GOS I have a record button on calls
