Your choices
When you first visit, you can accept all cookies, reject all non-essential cookies, or choose by category. You can change your mind at any time:
Rejecting a category deletes the cookies we set in it. You can also block or delete cookies in your browser settings; the site still works without non-essential cookies.
Cookies we use
Strictly necessary
Needed for the site to work and to remember your cookie choices. These cannot be switched off.

Remember things you choose to use between visits, such as your chat with our AI assistant. Without these, the chat is kept only until you close the tab.
| Cookie | Provider | Purpose | Duration |

Analytics & experiments
Help us understand how the site is used and test improvements (A/B tests). We look at the data in aggregate and do not use it to identify you.
| Cookie | Provider | Purpose | Duration |
|---|---|---|---|

A/B testing
If you accept analytics cookies, you may see one of several versions of a page while we test which works best. The gbuuid cookie keeps you on the same version. If you reject analytics cookies, you always see the standard version and are not included in tests.
Booking calendar
Our demo page can show Microsoft Bookings so you can pick a meeting time. It only loads when you click Show available times, and Microsoft then sets its own cookie to run the calendar. Microsoft's privacy statement applies to that cookie.
