What this is about
Cookies are small files a website stores on your device. Some are needed for the site to work at all. Others are there to tell me how the site is being used. It helps me understand what could be done to make the website more reachable to our community. You get to decide about the second kind, and you can change your mind whenever you like.
This page lists every cookie The Circle Clinic website actually uses, and why.
Your choice
When you first arrive you will see a banner asking about cookies.
- Necessary cookies are always on. Without them the site cannot remember your choices or keep forms working.
- Analytics cookies only run if you say yes. If you decline, Google Analytics does not load at all.
To change your mind later, click the cookie link in the footer of any page. Declining costs you nothing (everything on this website works either way).
Necessary cookies
These are needed for the website to function, and they do not require consent.
| Cookie | Set by | What it does | How long |
|---|---|---|---|
_wpfuuid |
WPForms | Recognises your browser so a form you started is not lost, and helps prevent spam submissions | 11 years |
wc_cart_hash_* |
WooCommerce | Remembers what is in your basket. Stored in your browser, not as a cookie | Until you clear it |
wordpress_*, wp-settings-* |
WordPress | Only set if you have an account and log in | Session to 1 year |
Analytics cookies
These only run if you accept them.
| Cookie | Set by | What it does | How long |
|---|---|---|---|
_ga |
Google Analytics | Tells apart one visitor from another, anonymously | 2 years |
_ga_GVMTC9GEQP |
Google Analytics | Keeps track of a single visit to the site | 2 years |
I use Google Analytics to see roughly how many people visit, which pages get read, and how people found the site. I look at it in the aggregate. I am not trying to identify individuals and I do not use it for advertising.
Order attribution cookies
If you use the shop, WooCommerce sets a group of cookies that record how you arrived at the site, so an order can be connected back to its source. These also only run once you have accepted analytics cookies.
| Cookie | What it does | How long |
|---|---|---|
sbjs_first, sbjs_first_add |
Records how you first found the site | 6 months |
sbjs_current, sbjs_current_add |
Records how you arrived this time | 6 months |
sbjs_session |
Counts pages viewed in this visit | 30 minutes |
sbjs_udata |
Basic browser information | 6 months |
sbjs_migrations |
Housekeeping for the above | 6 months |
Other services the site loads
- Google Fonts (fonts.googleapis.com) provides the typefaces. Loading a font means your IP address reaches Google’s servers.
- Google Tag Manager (googletagmanager.com) delivers the analytics tag, and only fires it once you have consented.
Turning cookies off in your browser
You can also block or delete cookies in your browser settings, for this site or all sites. Every browser does it slightly differently, and the help pages for Ecosia, Chrome, Safari, Firefox and Edge all explain it. Blocking necessary cookies may stop parts of the site working properly.
More about your data
How I handle personal information generally, including what happens when you contact me or become a client, is set out in the Privacy Policy.
Changes
If the cookies on the site change, I will update this page and the date at the top.
