Cookie policy

Cookies on this site.

We keep this simple. We set no analytics or tracking cookies until you accept them — and if you don't, the site works exactly the same. Last updated 21 July 2026.

What we use, and why

Analytics — only if you accept

When you accept, we load PostHog, a product-analytics tool, which sets a cookie to give your browser a random identifier and remember it between visits. We use it to count page views, see which parts of the site people use, and understand where our sign-up flow loses people — so we can make it better.

• What it's for: aggregate, first-party product analytics.
• What it is not: we don't use it for advertising, we don't sell the data, and there are no third-party ad or social-media tracking cookies on this site.
• Who processes it: PostHog, acting as our data processor (US region, us.i.posthog.com).
• When it loads: never before you click Accept. Reject, and it is never loaded at all; withdraw later here, and we clear it.

Remembering your choice

We store your accept/reject decision in your browser's local storage (a small key named tetra_cookie_consent) so we don't ask again on every page. This is functional — it exists only to honour the choice you just made — and is not used to track you.

Changing your mind

Use the Your choice control above at any time — accepting or rejecting takes effect immediately. You can also clear cookies and site data for this domain in your browser settings, which resets everything to "not chosen."
