Hefazot is a free parental control and content filter app. As a parent, you can use it to block adult, gambling, and harmful websites on your child's Android device. All filtering happens inside your phone — no information goes to an external server.

Key features:
• Automatically blocks adult, gambling, and harmful websites (DNS filter inside the device)
• Ability to add your own custom websites and words to the block list
• App Internet Lock — If you select a harmful app, it will not be able to access the Internet even if it is launched
• No restrictions on banking apps — bKash, Rocket, Nagad, etc. will run normally if you put them in the "Filter Avoid" list
• Battery saving — Does not consume unnecessary charge even when running in the background
• Settings protected with a parental PIN

Using VPN (VpnService) (Important information):
Hefazot uses Android's VpnService to run a local VPN inside the device, only checking DNS to block harmful domains and locking the Internet of your selected apps. It does not send your internet traffic to any external or company servers, view or store browsing content. It is not a remote proxy or traffic-routing service — all filtering happens on your phone.

Accessibility Service Usage (Important Information):
Hefazat uses an optional accessibility service, which is turned off by default and only works if you enable it. When enabled, it automatically redirects the browser tab to a safe page after a harmful page is blocked, so that the blocked content is not displayed repeatedly. To do this, the service simply reads the browser address bar (URL) and identifies the blocked page. It does not collect, store or send any of your personal information, passwords, keystrokes or browsing content anywhere. You can turn it off at any time in your phone settings.

Privacy:
All filtering happens on-device. Your browsing traffic is not sent to any external servers.

Use of VpnService (important disclosure):
Hefazot uses Android's VpnService to run a local, on-device VPN for the sole purpose of filtering DNS lookups to block harmful domains and to lock internet access for apps you select. It does NOT route your internet traffic through any external or company server, and does not inspect or store your browsing content. It is not a remote proxy or traffic-routing service — all filtering happens entirely on your phone.

Use of Accessibility Service (important disclosure):
Hefazot uses an OPTIONAL Accessibility Service that is OFF by default and works only if you turn it on yourself. When enabled, after a harmful page is blocked it automatically redirects the browser tab to a safe page so the blocked content is not shown repeatedly. To do this, the service reads only the browser's address bar (URL) to detect a blocked page. It does NOT collect, store, or transmit any personal data, passwords, keystrokes, or browsing content. You can disable it at any time from your phone's Settings.

Privacy:
All filtering happens on the device. Your browsing traffic is never sent to any external server.
