Karma Firewall blocks apps from accessing the Internet
About this app
Karma Firewall app lets you take control back of your phone and block internet traffic to and from specific apps. This is a simple yet powerful firewall with an easy to use intuitive GUI which allows you to protect your sensitive data.
Ever wondered why lots of apps that have no need for Internet access require Internet Permissions? Its usually either to display adverts or send your sensitive data back to servers in USA, China or Russia. Karma Firewall can block this traffic and protect your personal data. You do not need any technical skills to use, no complicated IP Addressing, Ports, Packet Filtering etc. Simply select the apps you want to block, and you are protected.
Karma Firewall is the safest, most trusted Android Firewall. Karma FW is completely different from all other VPN Firewalls. We intercept no allowed traffic. Karma FW requires NO Internet permissions. Without Internet permissions Karma FW CANNOT steal your data and send it anywhere.

Open the downloaded APK file from your Downloads folder
Tap "Install" and wait for installation to complete
Launch the app from your home screen
Make sure to re-enable Unknown Sources restrictions after installation for security.
How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be net.stargw.fok is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 65 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Karma Firewall first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Karma Firewall, and a listing is removed when the evidence for it stops holding up.
