Description
See where your data goes — detect trackers, data brokers, cookie syncs, and fingerprinting. Block them with Pro. Every webpage you load contacts dozens of companies you've never heard of. They sell your activity, sync your IDs across browsers, fingerprint your hardware, and adjust prices based on what they know about you. Purj shows you exactly who's watching — in real time, on every page, with names, categories, and confidence ratings. Then helps you make them stop. ━━━━━━━━━━━━━━━━━━━━━━ FREE — PRIVACY INTELLIGENCE ━━━━━━━━━━━━━━━━━━━━━━ Real-time tracker detection with named confidence ratings (Observed / Likely / Inferred), so you know exactly how each finding was made. - Data broker identification — 30+ companies named by category (LiveRamp, Tapad, TransUnion, Lotame, The Trade Desk, and more) - Cookie sync chain tracing — see IDs pass between ad-tech companies in multi-hop chains - Live network topology graph — interactive zoom and pan to explore third-party connections - Fingerprinting detection across canvas, WebGL, audio, and navigator APIs - CNAME cloaking detection — catches first-party subdomains that secretly alias to third-party trackers - Server-to-server inference (Meta CAPI, server-side GTM, identity resolution) - Privacy report export to Markdown + event log export to CSV - Letter-grade simple view — toggle between forensic detail and "show me the headline" ━━━━━━━━━━━━━━━━━━━━━━ PRO — ACTIVE PROTECTION ━━━━━━━━━━━━━━━━━━━━━━ 150,000 blocking rules from 15 open-source filter lists (EasyPrivacy, AdGuard, HaGeZi, and others), enforced via Chrome's modern declarativeNetRequest engine. - 7 fingerprint countermeasures — canvas noise, WebGL spoofing, audio randomization, navigator normalization, screen normalization, battery blocking, WebRTC IP leak prevention - Price Guard — auto-defends against surveillance pricing on 90+ travel, hotel, car-rental, e-commerce, and insurance sites.

No telemetry. No analytics. Your browsing data never leaves your browser. The only thing Purj transmits externally is your license key, sent to api.purj.ai approximately once a day to confirm Pro is active. Nothing else. Not your URLs, not your trackers list, not your scan results, not which sites you visit. ━━━━━━━━━━━━━━━━━━━━━━ Privacy intelligence for people who want to actually see what's happening — not just trust that something somewhere is blocking something. purj.ai
