dcoy

Most privacy tools hide where you browse. dcoy changes who advertisers think you are.
Data brokers, ad networks, and surveillance platforms build detailed profiles from your app behavior, browser fingerprint, and personal data. They sell that profile to anyone willing to pay. dcoy fights back.
WHAT DCOY DOES TODAY:
Blocks tracker domains on your device using Android's VPN framework, failing DNS lookups for known trackers from a blocklist drawn from EasyPrivacy and Disconnect.me
Submits CCPA and GDPR opt-out requests to a regularly updated list of consumer-facing data brokers, with profile repopulation monitoring
Injects browser fingerprint noise on Chrome, verified against EFF Cover Your Tracks
Injects behavioral noise to muddy the activity patterns advertisers profile you on
Reports your Profile Blur Score, a measurable index of how degraded your commercial surveillance profile has become
dcoy is not a VPN. It does not encrypt your connection or hide your IP address. It uses Android's VPN framework solely to filter tracker domains on your device. Because Android allows only one app to use this framework at a time, dcoy will let you know if another VPN app is active.
PROFILE BLUR SCORE
Every protection dcoy runs is reflected in your PBS, a live score with an auditable methodology. Verifiable through free public tools (Optery for broker presence, EFF Cover Your Tracks for fingerprint). The Phase 1 ceiling is 78, with mobile advertising ID, social media on-platform tracking, and transaction history disclosed as out of scope.
ON THE ROADMAP:
Location signal rotation (in design). Mobile advertising ID rotation guidance. iOS app.
BUILT FOR PEOPLE WITH REAL PRIVACY NEEDS
Journalists, executives, activists, and anyone who has looked up what data brokers know about them.
