Cookie policy

What we actually use

One strictly necessary session cookie may be set, but only if a form you submit fails validation. It holds your typed input so the form can show it back to you instead of making you start again. It is deleted when you close your browser and is never used to identify or follow you.

No other cookies are set by this website.

Display preferences are not cookies

Your dark mode and text size choices are stored in your browser’s local storage under the key exchange-site-prefs. This never leaves your device, is not sent to our server, and is not a cookie. You can clear it at any time in your browser settings, which simply resets the site to its defaults.

No third party cookies

Every asset on this site, including fonts and images, is served by us from this domain. Nothing is loaded from advertising networks, social platforms or content delivery networks, so no third party can set cookies through this site.

Managing cookies

You can block or delete cookies in any modern browser without affecting how this site works. The only feature that depends on the session cookie is form input recovery after a validation error.

If we ever add anything beyond strictly necessary cookies, we will update this page and ask for your consent before setting them, as the Privacy and Electronic Communications Regulations require.
