Cookies

No cookies

DevToolery does not set cookies — not for analytics, not for advertising, not for functionality. That is why you have never seen a consent banner here.

What we use instead

Two browser storage mechanisms, both of which stay on your device and are never transmitted:

• localStorage — your theme, editor preferences, favourite tools, and a short list of recently opened tool names. Names only; never contents.
• IndexedDB — snippets you have explicitly chosen to save in the workspace.

Why this is not the same thing

A cookie is attached to every request your browser makes to a domain, which is what makes it useful for tracking. localStorage and IndexedDB are never sent anywhere automatically — they are only readable by JavaScript running on this site, on your machine. Nothing here can follow you to another website.

Clearing it

The privacy centre shows exactly what is stored and removes any of it in one click. Your browser's own “clear site data” control does the same job.
