This page lists every cookie this site sets, what each one is for, and how long it lasts. It is the detail behind the banner. The wider notice, covering forms, email and what we do with what you send, is the privacy notice.
A cookie is a small piece of text a site asks your browser to keep and hand back on the next page. Some of them are how a site works at all. The rest are how it counts readers or remembers a choice, and those are the ones you decide about.
What we do before you choose
Nothing but the necessary group. No analytics cookie is set, and no optional feature loads, until you answer the banner. If you close the banner without answering, that stays true.
Necessary
These run before you choose anything, because without them the site cannot serve you a page or remember what you decided. There is no way to turn them off and still use the site.
| Cookie | Set by | What it does | How long |
|---|---|---|---|
__cf_bm | Cloudflare, for the hosts HubSpot serves this site from | Tells the network a browser is asking for the page rather than a bot, so the page is served instead of challenged. | 30 minutes |
_cfuvid | Cloudflare, for the hosts HubSpot serves this site from | Tells apart visitors who share one network address, so a limit on requests applies to one browser rather than to everyone behind the same connection. | Until the browser closes |
__hs_cookie_cat_pref | HubSpot | Records which groups you accepted, so the banner stops asking. It holds your answer and nothing else. | 6 months, set when you answer the banner |
Analytics
These count what gets read. They are off until you accept them, and nothing here is set if you decline.
| Cookie | Set by | What it does | How long |
|---|---|---|---|
__hstc | HubSpot | The main analytics cookie. Holds a visitor identifier and the timestamps of your first, previous and current visit. | 6 months, set on accepting analytics |
hubspotutk | HubSpot | The visitor identifier a form submission is stamped with, so a message and the pages read before it are one conversation rather than two. | 6 months, set on accepting analytics |
__hssc | HubSpot | Counts the pages in this session and decides when the session has ended. | 30 minutes, set on accepting analytics |
__hssrc | HubSpot | Records whether you restarted the browser, which is how a returning visit is told apart from a continuing one. | until you close the browser, set on accepting analytics |
Functionality
These remember a choice you made, or switch on an optional feature that is not needed to read the site. Nothing in this group sets a cookie, and nothing in it runs unless you accept it.
No cookie in this group.
Advertisement
Nothing on this site sets one. The group appears in the banner because the banner offers the same four groups everywhere, and leaving it there is more honest than hiding a switch that would matter if that ever changed.
No cookie in this group.
Changing your mind
Use the link in the footer of any page. It reopens the banner with your current answers showing, and a new answer replaces the old one straight away. You can also clear cookies in your browser, which resets everything on this page including the record of what you chose.
Turning analytics off does not change what you can read here. Turning functionality off removes an optional feature and nothing else.
How we keep this page honest
This list is not written from memory. We review the cookies this site sets before each release, and the durations above are what a browser was actually sent rather than what a vendor's documentation claims.
Questions about any of this go through the Talk to an architect door on our contact page, with privacy request in the message.
