CookieGhost by Alejandro
CookieGhost replaces tracking cookie values with random data so websites work normally but ad trackers receive meaningless information.
Extension Metadata
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
