Rethink DNS + Firewall + VPN for Android is an app that helps you control your internet privacy and security easily without needing root access. It combines a VPN using WireGuard, a firewall that blocks internet access for apps based on your preferences (like when apps run in the background or by category), and a DNS-over-HTTPS client that hides your DNS requests from ISPs and censors. You can route different apps through different VPN tunnels, block ads and malware sites, and monitor which apps connect to the internet. This gives you more control over your data, reduces tracking, and helps bypass censorship on your Android device.

Warning for #Android gapps traitors:
Uninstall the application: Android System SafetyCore, which has been automatically installed on most devices. It is used by Google to scan your data, just like Apple has been doing on iOS, but you have the choice to uninstall it. If you don't have it yet, watch out for it being installed silently over the next few days!
https://play.google.com/store/apps/details?id=com.google.android.safetycore
Be careful on GrapheneOS too if you have Google services installed.
While GrapheneOS will stop it from auto installing, it can nag you about installing it. And it won't tell you what it really is. Nor will most online resources.
Sandboxed Google Play compatibility layer: stop Play Store from attempting to auto-install some system component packages, such as "Android System SafetyCore" (com.google.android.safetycore) and "Android System Key Verifier" (com.google.android.contactkeys)

The phone is asking me to install this app, anyone knows information about if its truly need it or not? Im with the Google Play Services sandbox install
https://discuss.grapheneos.org/d/19193-android-system-safety-core
If you don't have GrapheneOS, it's going to automatically install itself again at some point after uninstalling it.
Locating the App
Go to Settings → Apps (or Apps & Notifications) → Show system apps. Look for “Android System SafetyCore.”
Check whether the app has any special permissions (e.g., internet access).
Uninstalling or Disabling
In many cases, you can uninstall an update or at least disable the app. Check the available options in the app info.
This is client side scanning. It's a way to spy on your device before it's encrypted.
