Privacy & Storage Test

Privacy and storage inspection tool that shows all stored cookies, localStorage items, sessionStorage data, and IndexedDB databases. Check what data websites are storing and clear storage if needed. Useful for privacy auditing and debugging storage issues.

Websites can store data in multiple ways: cookies (sent with every request), localStorage (persistent key-value storage), sessionStorage (temporary storage), and IndexedDB (structured database). This data can persist for days, weeks, or even years, making privacy auditing essential for understanding what information websites have stored about you.

Helpful questions

Frequently asked questions about Privacy & Storage Test

Use these answers to understand results, browser limitations, permissions, and sensible next troubleshooting steps.

What kinds of data can a website store in my browser?

A website may store cookies, localStorage items, sessionStorage entries, and IndexedDB records. Each storage type serves a different purpose, from keeping you signed in to caching preferences, saving app state, or storing larger structured datasets for offline-capable web apps.

Will clearing browser storage sign me out or reset website settings?

Yes, it often can. Removing cookies and storage data may sign you out, clear saved preferences, reset site-specific state, or delete cached data that a web app uses to function faster. That is why a privacy and storage review is useful before deciding what to remove.

Why should I check browser storage during troubleshooting?

Corrupted cookies, stale localStorage values, or outdated IndexedDB data can break login flows, saved settings, and application state. Inspecting storage helps you see whether the problem is caused by stored browser data instead of the server, the network, or the device itself.
