This Cookie Policy explains what cookies are, which cookies the Twelfth Brain website uses, and how you can control them.
Cookies are small text files placed on your device when you visit a website. They allow the website to recognise your device on return visits, remember your preferences, and collect information about how the site is used. Cookies may be set by us (first-party cookies) or by third parties whose services we use (third-party cookies). Similar technologies including web beacons, pixel tags, and local storage are also covered by this policy.
Strictly necessary cookies
These cookies are essential for the website to function. They cannot be disabled through our cookie controls, though you can set your browser to block them, which may affect website functionality.

| session_id | Maintains your session as you navigate the website | Session (deleted when browser closes) |
| csrf_token | Prevents cross-site request forgery on form submissions | Session |
| cookie_consent | Stores your cookie preferences | 12 months |
Analytics cookies
We use analytics cookies to understand how visitors use our website. Analytics data is collected in aggregate and anonymised where possible. We use a privacy-first analytics configuration that anonymises IP addresses before processing and does not enable cross-site tracking.
| Cookie | Provider | Purpose | Duration |

| _ga_[ID] | Google Analytics | Maintains session state | 2 years |
If we adopt a cookieless analytics solution such as Plausible or Fathom, no analytics cookies are set and this table will be updated accordingly.
Advertising and tracking
We do not use advertising cookies, retargeting cookies, or social media tracking pixels.
When you first visit our website, you will be shown a cookie notice allowing you to accept or decline non-essential cookies. You can update your preferences at any time by clicking Cookie Preferences in the website footer.
You can also manage cookies through your browser:
