About this extension
CookieGhost doesn't block cookies. It doesn't delete them. It randomize them with other datas.

Every website you visit drops tracking cookies to build a profile about you — your browsing habits, interests, purchases, and identity. Traditional privacy tools block or delete these cookies, which often breaks websites or triggers annoying cookie walls.

CookieGhost takes a different approach: it lets tracking cookies exist, but replaces their values with realistic random data in real-time. Google Analytics gets a fake client ID. Facebook gets a bogus pixel ID. Trackers think they're working, but your profile is pure noise.

HOW IT WORKS:
- Automatically detects 60+ known tracking cookies (Google Analytics, Facebook, TikTok, LinkedIn, HubSpot, and more)
- Replaces values with format-correct random data that passes validation
- Preserves functional cookies (login sessions, CSRF tokens, preferences) so websites work normally
- Strips cookies entirely from 50+ hardcore tracker domains

THREE PROTECTION MODES:
- Aggressive: Randomizes all uncertain cookies
- Balanced: Smart classification with conservative defaults
- Gentle: Only randomizes confirmed tracking cookies

PRIVACY FIRST:
- Zero data collection — everything stays on your device
- No accounts, no analytics, no telemetry
- Open source and fully auditable
