Private spaces and User profiles are a key feature to logically separate apps, data and pseudonyms in #GrapheneOS. Here is how a Nostr user could use it: Private spaces are an isolated space available from within the current user that you can opt to share data between. User profiles are logically separated users where nothing is shared between them and have different environments, home screens. Wallpapers, specific settings. - All profiles have their own separate unique VPN configuration. - Each profile or private space can have their own unique credentials, encrypting them separately. - Apps can't communicate with apps in other user profiles or private spaces. - Apps are updated globally on all profiles when updated on one of them for security. - You can install apps from the Owner user to other profiles, or from the currently used user to their private space. If you haven't used a Private Space yet, it likely replaces your use case for a user profile.

Users of apps integrating WebView like Keychat are more secure on #GrapheneOS than anywhere else. The Vanadium browser security hardening also targets the WebView. This means you get exploit mitigations like MTE and CFI covering the an app's WebView processes. We also release patches quicker than anyone else with exception of Chrome itself. You can go even quicker and use the Beta channel too. View quoted note →
