Cookie Policy
Brain uses the smallest possible set of cookies and similar storage — only what's needed to keep you signed in and remember your preferences. No third-party advertising or cross-site tracking cookies. Ever.

1. What cookies are
Cookies are small text files placed on your device by a website. Similar technologies (localStorage, sessionStorage) are covered by the same rules under the EU ePrivacy Directive and GDPR. This policy uses 'cookies' to mean all of them.
2. Cookies we set
| Name | Purpose | Type | Duration |
|---|---|---|---|
| sb-access-token / sb-refresh-token | Keeps you signed in to your workspace. | Strictly necessary | Session + 30 days (refresh) |
| brain.theme | Remembers your light/dark theme preference. | Functional | 1 year |
| brain.cookie-consent | Stores your choice on this banner so we don't ask again. | Strictly necessary | 1 year |
All cookies above are first-party and served from EU regions.
3. Third-party cookies
We do not set third-party advertising, analytics or social-media cookies. We do not use Google Analytics, Meta Pixel, or any cross-site tracker. If we ever add product analytics, it will be a privacy-respecting, EU-hosted tool and you will be asked for consent first.
4. Legal basis
Strictly necessary cookies are set on the basis of Article 5(3) of the ePrivacy Directive (no consent required). Functional and analytics cookies are only set with your prior consent under Art. 6(1)(a) GDPR. You can withdraw that consent at any time with the same ease you gave it.
5. Managing cookies
You can clear or block cookies through your browser settings at any time. Blocking strictly necessary cookies will sign you out and break parts of the app. If we offer optional cookies in the future, a cookie banner will let you accept, reject or fine-tune per category — rejecting is as easy as accepting.
6. Changes
When we add or remove a cookie, this page is updated and the 'Last updated' date above changes. Material changes are also announced in-product.
