Cookie Policy

Last updated: August 24, 2026

This Cookie Policy explains how the Mist website and dashboard use cookies and similar storage technologies. It is a companion to our Privacy Policy and applies to mist.dev and any subdomains we operate.

What are cookies

Cookies are small text files that a website stores in your browser. They let the site remember things about you between visits, such as whether you are signed in.

Most of what the Mist site uses is not a marketing cookie at all. This site is intentionally light on tracking, and this policy is transparent about exactly what is stored and why.

Session cookie (Better Auth)

The dashboard signs you in through Better Auth, our authentication library. When you log in, Better Auth sets a single session cookie that identifies your signed-in session.

This cookie is essential. Without it, the dashboard cannot keep you signed in or know which server settings to show you. It is an httpOnly, secure, same-site cookie, which means scripts cannot read it and it is only sent over HTTPS.

The session cookie expires when your session ends, such as when you log out, or after the session lifetime we configure. It is not used to track you across other websites.

No third-party tracking cookies

We do not set advertising cookies, and we do not allow third-party advertising networks to set cookies on our site. There are no tracking pixels, cross-site fingerprinting, or behavioral ad profiles.

We do not sell data about your browsing to anyone, and no outside company receives your data through cookies on this site.

Analytics

We collect limited analytics about how the website is used so we can improve it. This includes approximate page views, referrers, and the rough region a visitor is in.

This analytics data is aggregated and does not identify you personally. We do not tie website analytics to your Discord identity or to the data we hold about you in the bot. We do not use cookies to build a profile of your browsing across other sites.

Local storage and other storage

Beyond cookies, the site uses your browser's local storage for a small number of preferences. The most notable is your chosen theme (light or dark), so the site remembers it between visits. This is stored locally on your device and is not sent to us.

On the server side, Mist uses Redis for caches such as rate limits, cooldowns, and hot configuration. These are server-side caches that help Mist run quickly and reliably; they are not stored in your browser and are not cookies.

How to control cookies and storage

Because the only cookie we set is the essential session cookie, there are no advertising cookies to opt out of. You can control storage in your browser settings and can clear your site data at any time.

To end a session, log out of the dashboard. You can also clear cookies and site data for mist.dev in your browser, which will remove the session cookie and your saved theme preference. Removing the session cookie simply signs you out; it does not delete any of your account data.

Changes to this policy

We may update this Cookie Policy as the site evolves. We will update the "Last updated" date at the top of this page whenever we make changes.

If you have questions about cookies or storage on this site, contact us through our support server or by emailing [email protected].
