Cookie Notice
Last updated October 26, 2026
Draft: this document hasn't been reviewed by counsel yet and isn't in force. It describes how the service works today; the final version will replace it.
We set only the cookies needed to sign you in and remember your workspace. There are no analytics, advertising or tracking cookies, on this site or in the dashboard, so there's nothing to consent to.
This website
The marketing site sets no cookies, including on its contact form, and loads nothing from other companies: no analytics, no ad or social scripts, and its fonts are served from our own site.
It keeps one item in your browser's local storage, underpass:cookie-notice, so the short notice about cookies doesn't show again once you've closed it. It holds only the word “seen”, is never sent to us, and stays until you clear your browser's site data.
The dashboard
The dashboard sets cookies only once you sign in, and all of them are strictly necessary:
| Name | What it does | Kept |
|---|---|---|
sb-…-auth-token | Keeps you signed in (set by our sign-in provider, Supabase). A long session may be split into numbered parts (.0, .1). | Up to 400 days, renewed while you use the dashboard; removed when you sign out |
sb-…-auth-token-code-verifier | While you sign in: proves that the sign-in coming back to us is the one you started. | Until that sign-in finishes |
tn_workspace | Remembers which of your workspaces you're working in. | 1 year; removed when you leave that workspace or delete your account |
Signing in with Google takes you to Google, which uses its own cookies there under Google's privacy policy.
Storage in your browser
The dashboard keeps a few preferences in your browser's local storage. They never leave your browser:
| Key | What it remembers |
|---|---|
theme | Light or dark mode, if you picked one |
dns-layout | Rows or cards, on the DNS page |
console:notifications-seen | Which notifications you've already seen |
Your choices
You can block or delete cookies in your browser settings. Without the sign-in cookie you can still browse this site, but you can't use the dashboard.
