みやブル

みやブル (Miyaburu) is a dedicated security extension focused on preventing internet fraud that standard antivirus tools often miss. It detects phishing, one‑click fraud, fake sales sites, and fake warnings, protecting users from theft of financial and personal information. The service offers a 30‑day free trial with full functionality; after the trial a ¥210 monthly (30‑day) fee applies via Google Play.

Miyaburu uses a unique triple‑engine approach — blacklist, heuristic, and AI detection — to block or warn about dangerous sites across Chrome, Y! Browser and many in‑app browsers (Google, Gmail, Yahoo! JAPAN, LINE, X, Instagram, Facebook). The extension collects threat data from public institutions, shows warning screens with explanations, and uses Accessibility features to read the active URL (only for fraud detection). Note: Miyaburu assists in identifying risky pages but does not provide a legal determination of fraud. Supported on Android 10.0+ (10MB free space).
