Auto-Clear Site Data

Automatically clears website data (cookies, localStorage, indexedDB, cache, service workers) when you leave a site — by closing tabs, navigating away, or when tabs are discarded — helping you maintain privacy and free up storage. 🧹✨



🎯 Key Features

⏱️ Smart Automatic Clearing

• 🤖 Clears data automatically after a configurable delay (0-3600 seconds) when you exit a site
• ⚡ Supports instant clearing (0 seconds) for immediate privacy
• 🚀 Optional "Clear on Startup" to clean sites from your previous session
• 🎮 Manual "Clear Now" with granular control over which data types to clear

🛡️ Advanced Privacy Controls

• 🎚️ Whitelist/Blacklist Modes: Clear everything except specific sites, or only specific sites
• 📊 Granular Data Types: Choose exactly what to clear — cookies, localStorage, sessionStorage, indexedDB, cache, service workers
• 🔍 Deep Clear: Optionally clear parent domain data (e.g., clear accounts.google.com → clear google.com too)
• 🔀 Redirect Catching: Clears data from sites you navigated through quickly (configurable X-step detection)

🗂️ Firefox Container Support

• 📦 Full support for Firefox Multi-Account Containers
• 🎯 Per-container exemption rules
• 🔐 Independent container-scoped vs. global data clearing

🧠 Smart Dependency Tracking

🚪 When Data Gets Cleared

The extension clears data when you leave a site through:
