FAQ
Common questions
Does CookieKiller accept or reject cookies?
CookieKiller always rejects non-essential cookies. It clicks "Reject All," "Only Necessary," or equivalent. It never accepts tracking cookies. If no reject option exists, it removes the banner without accepting.
Is my data safe?
Zero data collected. No browsing history, no personal info, no analytics. Only your popup counter and whitelist are stored — 100% locally. Code is open-source for full verification.
Will it break any websites?
CookieKiller only touches cookie consent banners, never modifying page content. If a site needs cookies, whitelist it with one click.
How is this different from "I don't care about cookies"?
That extension was acquired by Avast (ad-tech) and often accepts cookies — harming your privacy. CookieKiller is independent, open-source, always rejects, collects zero data.
Does it work outside of Europe?
Yes. Cookie banners appear worldwide due to GDPR, CCPA, LGPD, POPIA and similar laws. Works on any site, any country, 30+ languages.
Is it really free?
Completely free. No premium tier, no ads, no catches. MIT licensed. Privacy tools should be accessible to everyone.
