Cookie Policy

Last reviewed: 23 July 2026

This page explains the cookies and browser storage RunTheTests uses. The short version: very little, and nothing that tracks what you do inside a tool.

1. What cookies are

Cookies are small files a site stores in your browser. Related technologies — localStorage and sessionStorage — do a similar job. We use the minimum needed for the site to work and to remember your preferences.

2. What we store ourselves

  • Theme preference — a single value in localStorage remembering whether you chose light, dark or system. It never leaves your browser.
  • Tool settings — some tools remember your last choices (units, options) in local storage so you do not re-enter them. This too stays on your device.

None of this is a tracking cookie, and none of it is sent to us. You can clear it any time through your browser settings.

3. What we do not store

We do not set analytics or tracking cookies on what you type, paste or upload into a tool. The inputs to a tool are not logged and are not tied to any identifier. Tools that make a network request to work do so to perform the lookup, not to track you.

4. Advertising cookies

Some pages carry advertising, and advertising networks may set their own cookies to measure and target ads according to their own policies, which we do not control. These appear only on pages that show ads. Pages that handle passwords, keys or encryption carry no advertising and no third-party scripts at all, so no advertising cookie is ever set on them.

5. Managing cookies

You control cookies through your browser: you can block them, delete them, or browse privately. Blocking our small preference storage only means the site forgets your theme and tool settings — every tool still works. Blocking third-party cookies limits ad personalisation without affecting the tools.
