## Description

"Infostealer" malware steals your browser's cookies and allows an attacker to log in to your accounts <strong>without a password and without triggering 2FA</strong>, 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.

<strong>Features:</strong>
<ul><li>Automatic cleaning every 30 minutes to 24 hours, or when the browser starts</li><li>Two modes: list of selected sites, or “clean everything except my whitelist”</li><li>One-click presets: Discord, Google, Steam, PayPal, Microsoft, social media…</li><li>Clears localStorage / IndexedDB — where tokens like Discord’s are stored</li><li>Direct links to “connected devices” pages to revoke sessions on the server side</li><li>Breach checks: email via Have I Been Pwned, password via the k-anonymity API</li><li>Cleanup log, interface in 5 languages (FR, EN, ES, DE, IT)</li></ul>
<strong>Let’s be honest:</strong> 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.

<strong>Privacy:</strong> No data leaves your device. No servers, no accounts, no statistics.
