FAQ

Q: Does this extension slow down my browser?

No. The extension uses a lightweight service worker that only runs when you click the icon. It has minimal impact on browser performance.

Q: Can I undo clearing data?

No. Once data is cleared, it cannot be recovered. Be careful when using "All Sites" mode with History enabled.

Q: Why can't I clear data on chrome:// pages?

Chrome extensions cannot access or modify internal Chrome pages (chrome://, about://, etc.) for security reasons.

Q: Does this work in Incognito mode?

The extension can work in Incognito mode if you enable it in Chrome Extensions settings. However, Incognito mode already limits data storage.

Q: What's the difference between Local Storage and Session Storage?

• Local Storage: Persists until explicitly cleared
• Session Storage: Cleared when the tab/window is closed
• Both are cleared by this extension if enabled
