Blokada works across all of your apps, not only the browser. It doesn't require root, supports both wifi and mobile networks, and is perfectly safe and simple to use. Just turn it on, and it will do the job silently!
NetGuard provides simple and advanced ways to block certain apps' access to the internet without the help of root privileges. Applications and addresses can individually be allowed or denied access to your Wi-Fi and/or mobile connection, allowing you to control which apps are able to call home or not.
Revoking Android permissions from apps often let apps crash or malfunction. XPrivacyLua solves this by feeding apps fake data instead of real data.
