Karma Firewall: Simple, Powerful Privacy Protection
Karma Firewall gives you full control over your Android device by blocking internet traffic to and from specific apps. With its user-friendly interface, this firewall simplifies protecting your sensitive data without needing advanced technical skills.
You may notice that many apps request internet permissions even when they don’t need them. This is often for advertising or to send your data to servers in the USA, China, or Russia. Karma Firewall prevents this unwanted traffic and safeguards your personal information. There’s no need for complex settings or configurations—just select the apps you want to block, and you’re secure.
Karma Firewall stands out as a trusted and safe solution for Android. Unlike VPN firewalls, it doesn’t intercept allowed traffic and doesn’t require internet permissions, so it can’t misuse your data.
