Privacy
Cookie Policy
Which cookies I use, what they're for and how to change your mind. Analytics cookies stay off unless you accept them.
What cookies are
Cookies are small files a website saves in your browser. Sites can also save information in your browser's local storage, which works in a similar way. This page covers both, and calls them all cookies.
I sort them into two groups: essential cookies, which the site needs and which are always on, and analytics cookies, which I only use if you say yes.
Essential cookies
All but the last are stored in your browser's local storage, never sent to me or anyone else, and stay until you clear your browser data.
| Name | What it's for | How long |
|---|---|---|
theme | Remembers whether you picked the light or dark theme. | Until you clear it |
stcm. | Remembers that you've answered the cookie banner, so I don't ask again on every page. | Until you clear it |
stcm. | Records that essential cookies are on (they always are). | Until you clear it |
stcm. | Remembers whether you accepted analytics cookies. | Until you clear it |
_GRECAPTCHA | Google reCAPTCHA, on the contact page only: stops spam getting through the contact form. | 6 months |
Analytics cookies
These help me see how people use the site (which pages they visit, where they click and how far they scroll) and run A/B tests, so I can make it better. They're only set if you accept analytics cookies.
| Name | Provider and purpose | How long |
|---|---|---|
_ga | Google Analytics: tells visitors apart. | 2 years |
_ga_BV1RJ7BV99 | Google Analytics: keeps track of your visit. | 2 years |
_clck | Microsoft Clarity: tells visitors apart. | 1 year |
_clsk | Microsoft Clarity: joins the pages you visit into one session. | 1 day |
| Mida cookies | Mida: shows you the same version of a page during an A/B test and records which version you saw. | See Mida's policy |
If you don't accept, these cookies aren't set and Mida and Clarity don't load. Google Analytics may still receive basic, cookieless signals (such as a page view) that can't be linked to you.
For more detail, see how Google uses cookies (opens in a new tab), the Microsoft privacy statement (opens in a new tab) and Mida's privacy policy (opens in a new tab).
Changing your mind
You can change your choice at any time with the "Change cookie settings" button at the top of this page. Every page links here from the Cookies link in its footer. If you withdraw consent, the page reloads without the analytics scripts.
You can also block or delete cookies in your browser's settings. The Information Commissioner's Office (opens in a new tab) explains how.
