Bangladesh's free cybersecurity app — in Bengali and English. Detect scams, scan your device, check any link, and protect your money.
Bangladesh has over 50 million active mobile internet users — yet cybersecurity awareness is extremely low outside educated urban circles. bKash fraud, fake loan apps, Facebook hijacking, SIM swap, smishing — all rampant, with no widely available Bengali-language resource to fight back. Surokkha closes that gap.
Built for every Bangladeshi — from a first-time smartphone user to an IT professional. Three reading levels so nobody is left behind.
9 on-device checks: screen lock strength, unknown app sources, dangerous permission combinations, accessibility service hijacks, device admin apps, notification listener access, Google Play Protect, OS patch age, and developer mode.
100% on-device · nothing sent to serversPaste any URL or point your camera at a QR code. Checked against a local Bangladesh-specific blocklist (bKash, Nagad, Facebook phishing), 4 heuristic checks, and optional Google Safe Browsing — before you ever tap.
Privacy-safe hash matchingType any number to check it against a community-reported scammer database before you call back or send money. Only a SHA-256 hash of the number is ever transmitted — your raw number never leaves your device.
Hash-only lookup · raw number stays local30+ articles on the scams most affecting Bangladeshis — bKash/Nagad fraud, Facebook hijacking, fake loan apps, smishing, prize call scams, Google account security, and more. Written at three levels: Simple, Normal, Technical.

Three types of users, one app — progressive depth means every level finds exactly what they need.
Rickshaw pullers, shopkeepers, garment workers, rural users, elderly users — people using bKash and Nagad daily but unfamiliar with social engineering. Bengali by default, ultra-simple language, real stories from people like them.
Students, office workers, gig workers, social media users. People who use mobile banking and e-commerce daily and want deeper guides, threat news, peer discussion, and a device scanner.
IT professionals, teachers, journalists, NGO workers who want technical depth, sharing tools, and the ability to help spread awareness in their communities. Technical article layer + sharing tools built in.
"Scammers are experts. Being targeted is not your fault.Surokkha's guiding principle — non-punitive, community-driven, empowering.
Sharing your story protects others."
