Cookie Policy
Effective date: June 18, 2026.
This Cookie Policy describes the cookies and similar local-storage technologies that Brume sets on your device when you visit brume.run (the marketing site) and app.brume.run (the dashboard). It is short because Brume sets very few of them.
1. What is a cookie
A cookie is a small text file that a website asks your browser to store. It usually contains the website's name and a unique value. Cookies are commonly used to remember you between page loads. Some cookies expire when you close your browser ("session cookies"); others persist for a fixed period ("persistent cookies").
2. Cookies on the marketing site (brume.run)
| Cookie name | Purpose | Type | Expiry | Required? |
|---|
brume_theme | Remember your light / dark mode preference | Functional | 1 year | No |
brume_analytics | First-party analytics (page views only) | Analytics | 1 year | No |
brume_session | Authentication if you sign in from the marketing site | Essential | 7 days | Yes (only if you sign in) |
The marketing site does not set any third-party cookies. We do not use Google Analytics, Meta Pixel, or any cross-site tracking technology. The optional brume_analytics cookie is set by a self-hosted counter that runs on our infrastructure; the data never leaves our servers.
3. Cookies on the dashboard (app.brume.run)
| Cookie name | Purpose | Type | Expiry | Required? |
|---|
__Secure-better-auth.session_token | Keep you signed in | Essential | 7 days | Yes |
This cookie is set by Better Auth, the authentication library we use. It is HTTP-only (JavaScript cannot read it), Secure (HTTPS only in production), and SameSite=Lax (the browser sends it only on same-site navigations). It contains a signed session identifier; it does not contain your password or email.
The dashboard does not set any analytics cookies or third-party cookies.
4. Local storage
The marketing site uses localStorage to remember your theme preference and analytics opt-in state. The dashboard uses localStorage for theme preference only. None of this data is sent to any third party.
5. How to control cookies
You can clear cookies and local storage at any time via your browser settings. The exact steps depend on your browser:
- Chrome: Settings → Privacy and security → Clear browsing data
- Firefox: Settings → Privacy & Security → Cookies and Site Data → Clear Data
- Safari: Preferences → Privacy → Manage Website Data
Clearing the dashboard session cookie (__Secure-better-auth.session_token) signs you out of Brume. You will need to sign in again.
Clearing the marketing-site cookies resets your theme preference to the system default and removes your analytics opt-in.
6. Do Not Track
We respect browser "Do Not Track" signals. If your browser sends DNT: 1, we do not set the brume_analytics cookie regardless of whether you have accepted the cookie banner.
7. Changes
We will update this Cookie Policy if we add or remove cookies. Material changes will be notified by email and on the dashboard. The current set of cookies is documented above; check the page periodically.
