Firewall - No Root Blocker

Firewall is an application that provides a unique approach to protecting your device and data. Unlike other security apps, Firewall blocks all network traffic by default and only allows trusted apps to access the internet. This means that even system apps, OEM bloatware, and background services are blocked unless you specifically whitelist them. This ensures that your data stays on your device and is not sent to remote servers or used for analytics.

The way Firewall works is by creating a local VPN on your device, through which all network traffic is routed. This allows for a completely local VPN, with no traffic leaving your device through an external server. Blocked apps will hit a dead end, while allowed apps can bypass the VPN and connect normally. This provides a secure and efficient way to control internet access for each app on your device.

One of the key features of Firewall is its per-app internet control. This means that every app is blocked by default, and you can choose to whitelist only the apps you trust. You can also toggle Wi-Fi and mobile data separately for each app, block system apps and OEM bloatware, and use bulk allow or block buttons for quick setup. The app also allows you to filter apps by all, user, or system, and changes take effect immediately without the need to restart.

In addition to blocking internet access for apps, Firewall also offers tracker, ad, and fingerprint blocking. It intercepts every DNS query and checks it against a blocklist of known tracker, ad, and fingerprinting domains. This means that over 130 tracker and ad domains are blocked by default, and you can also download community blocklists or add your own custom blocked domains. You can also whitelist specific domains to prevent false positives and toggle tracker blocking independently from the firewall.

Firewall also offers DNS over HTTPS (encrypted DNS) to protect your browsing privacy. This feature encrypts your DNS queries so that your ISP cannot see every domain you visit. You can choose from Cloudflare, Google, or Quad9 as your DNS provider and switch providers with a single tap. This feature also works alongside tracker blocking for maximum protection.

Other features of Firewall include always-on protection, real-time connection logs, traffic stats, and a focus on privacy and trust. The app does not collect any data, use any advertising SDKs or third-party services, and is fully open source for users to audit the code themselves. It is also compatible with a wide range of Android devices, from version 6.0 to 15, and does not require root access. Firewall is a free and open-source app created by Marko Zanoski with a focus on originality and SEO optimization.
