The App
TacUNS Firewall
One-liner (140 chars)
Free Android firewall, ad blocker & per-app DNS control. No root, no signup, 100% on-device. Made in India.
Short Description (2–3 sentences)
TacUNS Firewall is a free Android security app that blocks ads, trackers, malware, and scam domains entirely on-device. It uses 84,000+ community-curated threat domains, offers per-app Wi-Fi and Mobile Data control, and requires no root or signup. Built solo by a network security engineer in Chennai, India.
Long Description
TacUNS Firewall gives your Android phone the same DNS-layer protection that enterprise networks use to block ads, malware, phishing, and trackers — completely on-device, with no cloud server, no account, and no subscription.
Built by a Network Security TAC Engineer who spends his working day troubleshooting Next-Gen Firewalls for Fortune 500 companies, TacUNS Firewall applies the same threat-intelligence principles to your personal device. It blocks 84,000+ domains across five curated global threat lists and lets you toggle each list independently — so you choose the level of protection you want.
Beyond blocking, TacUNS Firewall gives you per-app control over Wi-Fi and Mobile Data independently, a real-time 0–100 Security Posture Score, a 24-hour DNS activity timeline, a live world map of where your apps connect, geo-blocking for high-risk country TLDs, scheduled blocking for parental control, and a 7-day exportable privacy report. All of this runs entirely on your Android device — your data never leaves your phone.

Quotable Statements
“The same firewall protection Fortune 500 companies pay millions for should not be locked away from the people who need it most — everyday Android users.”
“UPI scams have stolen ₹1,000+ crores from Indians. The protection layer to stop these scams already exists in enterprise networks — we just brought it to consumer phones.”
“TacUNS Firewall is privacy maximalism by design. No cloud servers. No accounts. No data collection. Your phone, your rules.”
“I built this on nights and weekends for 18 months while working full-time. It's possible to build serious cybersecurity tools as a solo indie developer in India.”
