Cookie & Local Storage Privacy Inspector

A live cookie inspector for your browser: see which cookies, local storage and session storage items this website keeps, what each is likely for, and clear this page's storage in one click.

This shows what THIS page is currently storing in your browser — for privacy reasons, tools cannot read another website's cookies remotely. To inspect a different site, open its page and use your browser's developer tools (Application tab).

Live browser storage

Reading your browser storage…

HttpOnly cookies (often login sessions set by the server) are hidden from all scripts by design, so no in-page tool can list them — that's a security feature.

Categories are matched from well-known names (for example _ga is Google Analytics). Anything we don't recognise is marked Unknown rather than guessed. Values that look like login tokens are hidden on screen.

Embed this inspector on your site

Heads up: browsers keep embedded frames separate, so the embed can only show DigiMetrics Hub's own frame storage — never your site's cookies. The note is included in the code for anyone who embeds it.

What cookies, local storage and session storage do

Cookies

Small text files sent to the server with every request. Used for logins, preferences and — from third parties — tracking. Can expire or last years.

Local storage

Up to about 5 MB per site, kept only in your browser until cleared. Apps use it for settings, drafts and cached data.

Session storage

Like local storage, but tied to one tab. It's wiped as soon as you close that tab.

Why this matters for privacy

Cross-site tracking

Advertising cookies such as _fbp or IDE let ad networks recognise you on every site that carries their code.

Analytics profiles

Cookies like _ga give you a long-lived ID so a site can link all your visits together.

Beyond cookies

Clearing cookies doesn't stop browser fingerprinting, which identifies you from your device's settings instead.

How to clear cookies and storage manually

Chrome / Edge

Settings → Privacy and security → Delete browsing data → tick “Cookies and other site data”.

Firefox

Settings → Privacy & Security → Cookies and Site Data → Clear Data.

Safari

Settings → Privacy → Manage Website Data → Remove All (iPhone: Settings → Safari → Clear History and Website Data).

One site only

Click the padlock or site icon in the address bar → Cookies and site data → remove the entries for that site.

Frequently Asked Questions

What's the difference between a cookie and local storage?+

Cookies are small pieces of data that the browser sends to the website's server with every request, so they're used for logins and tracking and can have an expiry date. Local storage holds more data (about 5 MB), stays only in your browser, is never sent automatically to the server, and lasts until it is cleared.

Can this tool see cookies from other websites?+

No. Browsers enforce a same-origin rule: a page can only read its own cookies and storage, never another site's. This tool shows what digimetricshub.com stores in your browser. To inspect another site, open it and use your browser's developer tools, under the Application or Storage tab.

Are cookies dangerous?+

Cookies can't run code or carry viruses; they are just text. The risks are privacy and security: third-party advertising cookies can track you across sites, and a stolen session cookie can let someone into your account. Clearing cookies regularly and blocking third-party cookies reduces both risks.

How do I clear cookies in my browser?+

In Chrome and Edge, open Settings, then Privacy and security, then Delete browsing data, and tick Cookies. In Firefox go to Settings, Privacy & Security, Cookies and Site Data, Clear Data. In Safari go to Settings, Privacy, Manage Website Data, Remove All. On mobile the same options are under the browser's privacy settings.

What is a third-party cookie?+

A third-party cookie is set by a different domain than the site you are visiting, usually an ad network or social widget embedded on the page. Because the same third party appears on many sites, it can follow you across the web to build an advertising profile. Safari and Firefox block them by default.
