About Kronos Firewall
Kronos 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. Kronos 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.
Kronos FW app requires no internet permissions! No data or information about you or your phone will ever be sent back to servers in China, Russia or the USA. In fact the app only requires the start on boot permission. This is fully configurable. If you tell the app not to start on boot, it will not start on boot. No other firewall on the market requires so few permissions. No Internet permissions means our Kronos FW itself cannot communicate anywhere. Kronos FW does NOT require root. Kronos FW is the safest, most trusted Firewall on the Google Play App Store.

Effectively blocks user apps. Seems like it cannot block system apps and most of them are not listed either. It doesn't actively eating up cpu cycles like other firewall apps which doesn't drains battery, a plus. Most lightweight and fast firewall out there. Developer, make it blocks all system apps if the user needed. I will upgrade to 5 stars once it improves as reported. Thanks

Nice interface, simplistic , black background is nice, very unique in timestamps for data packets next to app that have been sent ,..even when app is allowed to. Q: where is vpn? Suggestion-> if it were me and i could change 1 thing, it is the ability to fine grain filter a app say for example a APK file from online that sends out mysterious connections ,...to be able to filter the ones that connect to admob and other junk automatically, that would be huge. The greyshirts firewall attempts to but fails.

Sure it does have one good thing going for it. It's easy to use. However it won't stay on or any length of time. It's pretty much another useless offer .

It does work if you want to block complete access to an app. I need more features that allows me to control WiFi and data connection. Like I want some apps to connect to WiFi but not data plan.

Great piece of work! Contrary to some comments, this hidden gem has option to stop access to system apps. At this size there can't be many complaints.

First, please don't expect a user to click all 228 user apps and hundreds of system apps to disable. Give an option to enable all and disable all. After disabling, I will enable one by one. Do this 5 stars pending for you.

I really liked this app compared to the other ones I had used, simple and easy display. But unfortunately it kept freezing up after boot, reinstalled a few times but same problem.

Sadly this one doesn't list all apps. Have to uninstall. It looked promising in the beginning.
