About Blocker
Blocker is a component controller for Android applications that currently supports using PackageManager and Intent Firewall to manage the state of components. It can be seamlessly switched between these controllers, and for application rules, you can export and import them. Additionally, it is compatible with backup files generated by MyAndroidTools, and you can effortlessly convert them to Intent Firewall rules. The application also has the potential to be extended in the future.
Privacy and F-Droid
F-Droid builds Blocker from its published source code and flags anti-features such as ads, tracking or reliance on non-free services.
