Cookie Policy
Last updated: 9 November 2026
This policy explains which cookies and similar technologies the GoCerebro websites use (gocerebro.ai, beta.gocerebro.ai and investor.gocerebro.ai), why, and how you can control them. It completes our privacy policy.
The websites are published by GoCerebro, Inc. You can reach us at privacy@gocerebro.ai.
1. What cookies and browser storage are
A cookie is a small text file that a website saves in your browser and reads again on your next visit. Browser storage (such as "local storage") works in a similar way but stays on your device and is not sent to our servers. In this policy, "cookies" covers both.
2. Our approach
We only use cookies that are needed to make the websites work or to remember a choice you made. These are strictly necessary, so the law does not require your consent for them, and we do not show a cookie banner.
We use no analytics, advertising, social media or tracking cookies. We do not let advertisers or data brokers place cookies through our websites.
3. The cookies we use
| Name | Type | Set by | What it does | How long |
|---|---|---|---|---|
locale |
Cookie | GoCerebro | Remembers the language you chose (English or French) on all our websites | 1 year |
sb-[project-id]-auth-token (may be split into .0, .1, …) |
Cookie | GoCerebro, through Supabase | Keeps you signed in, if you have an account | Until you sign out, at most 400 days |
sb-[project-id]-auth-token-code-verifier |
Cookie | GoCerebro, through Supabase | Secures the sign-in step | Removed once you are signed in |
theme |
Browser storage | GoCerebro | Remembers whether you chose light or dark mode | Until you clear it |
These cookies are "first party": they belong to our own websites, and we do not use them to follow you across other websites.
4. The intro video
Our homepage offers a short intro video hosted on YouTube. It only loads when you press play, and it uses YouTube's privacy enhanced mode (youtube-nocookie.com), which does not set cookies before you play the video. Once you play it, YouTube (Google) may store information in your browser under its own privacy policy. If you prefer not to, simply do not play the video.
5. Cerebro Lite
The Cerebro Lite browser extension keeps your recent checks in the extension's storage, on your computer only. It does not use cookies to track you on the websites you visit. Removing the extension deletes this storage. See section 3a of the privacy policy.
6. How to control cookies
You can delete or block cookies and browser storage at any time in your browser settings:
If you block or delete them, you will be signed out, and the websites will forget your language and theme. Everything else keeps working.
7. Changes to this policy
If we ever want to use cookies that are not strictly necessary (for example to measure audience), we will ask for your consent first, let you refuse as easily as you accept, and update this policy before doing so. The date at the top shows the latest version.
8. Contact
Questions about cookies or your data: privacy@gocerebro.ai. You can also contact the CNIL (cnil.fr) or the data protection authority in your country.
