Cookie notice
Last updated 9 October 2026
This notice is published in English only. The rest of the site is available in seven languages, but a legal notice should say exactly what it means, so we do not publish machine translations of it. If anything here is unclear, please ask us and we will explain it in your language.
This site uses very few cookies, and the banner you saw on your first visit is the whole of the choice. This page explains what each one is for.
What we set
Strictly necessary
- lh_consent and lh_consent_timestamp record the choice you made on the banner and when you made it, so we do not ask again on every page.
- A session cookie set by our authentication provider keeps you signed in while you are using the application. It is not set for visitors who are only reading the public site.
- If you open the chat assistant, it keeps the conversation in your browser tab, not a cookie (mps_chat_v1, mps_chat_conversation and mps_chat_open), so it carries on as you move between pages. It is discarded when you close the tab.
Measurement
- A random identifier stored in your browser tab, not a cookie, which lets us count one visit as one visit across several pages. It is discarded the moment you close the tab and it is never linked to a name unless you fill in a form yourself.
Marketing, only if you choose "Accept all"
- __kla_id is set by Klaviyo, the service we use for marketing emails, to recognise you when you come back to the public site. It can last up to two years, depending on your browser. Alongside it, Klaviyo keeps a few entries in your browser's local storage (klaviyoOnsite, $referrer, $last_referrer, kl-post-identification-sync) recording the pages that referred you and whether it has recognised you.
- Klaviyo is only loaded on the public pages of this site, and only after you choose "Accept all". It is never loaded inside the signed-in application.
Choosing "necessary only"
Choosing "necessary only" stops the measurement described above entirely, and Klaviyo is never loaded. It does not degrade the site: nothing on it depends on being measured. The measurement also stops automatically if your browser sends a Do Not Track signal, and no measurement or marketing of any kind runs inside the signed-in application.
Changing your mind
Clearing this site's cookies in your browser will make the banner appear again, and you can answer differently. Choosing "necessary only" then deletes the Klaviyo cookie and its local storage entries described above. Your browser's own settings can also block cookies for this site altogether; the parts of the product that need a session to keep you signed in will stop working if you do that, which is a limitation of how signing in works rather than a choice we have made.
Third parties
We run no advertising trackers and no social media pixels on this site. The one marketing service is Klaviyo, described above, which runs only if you choose "Accept all". Where a page embeds a payment form, that provider sets its own cookies to make the payment work; see the privacy notice for who those providers are.
