CookieCleaner

Automatically clears cookies and sessions of chosen sites to limit cookie theft. Free, open-source, zero telemetry.

"Infostealer" malware steals your browser's cookies and allows an attacker to log in to your accounts without a password and without triggering 2FA, since the session is already authenticated. A stolen cookie is only useful as long as the session is valid. CookieCleaner regularly clears cookies and session tokens from the sensitive sites of your choice: this reduces the window of opportunity for exploiting a stolen cookie from several weeks to just a few hours. Features: Automatic cleaning every 30 minutes to 24 hours, or when the browser starts Two modes: list of selected sites, or “clean everything except my whitelist” One-click presets: Discord, Google, Steam, PayPal, Microsoft, social media… Clears localStorage / IndexedDB — where tokens like Discord’s are stored Direct links to “connected devices” pages to revoke sessions on the server side Breach checks: email via Have I Been Pwned, password via the k-anonymity API Cleanup log, interface in 5 languages (FR, EN, ES, DE, IT) Let’s be honest: CookieCleaner reduces the risk; it doesn’t eliminate it. If malware is active on your device, it can steal your cookies again. This tool complements a secure system, antivirus software, and 2FA—it does not replace them. Privacy: No data leaves your device. No servers, no accounts, no statistics. Full source code: https://github.com/FrankkDarko/CookieCleaner
