Two cookies, both set by analytics. This page names them, says what each one is for and how long it lasts, and explains how to refuse or remove them.
_ga stores a randomly generated identifier for your browser and lasts about two years. It allows several page views to be counted as one reader rather than several. _ga_ENZYSY7FX1 serves the same purpose for this site specifically and records where one visit ends and the next begins.
Both are set by Google Analytics. Neither stores your name, your email address or anything you have sent me. Both are first party, meaning they can be read only by this domain.
Understanding which pages are read, how readers arrive, and how the site performs. That is the whole purpose. They are not used for advertising, and nothing stored in them is sold or shared with a data broker.
Clearing cookies for this domain in your browser removes both. Most browsers can also block them before they are set, either for this site or for every site, from the privacy or site settings menu.
A content blocker or a privacy-focused DNS resolver stops the analytics loading at all, and many block it by default. Nothing on this site stops working when it is blocked. Google also publishes a browser extension that opts you out of Google Analytics on every site.
The network in front of this site may set its own to distinguish automated traffic from human traffic. It carries no identity and is not readable by this site.
Enquiries go through Upwork rather than a form on this site, so nothing you write to me passes through this page or gets stored in your browser by it. What that means for your data is on the privacy page.
If something here is unclear, or you find a cookie this page does not account for, tell me through the Upwork. Name the cookie and the page you saw it on.
There is no email address and no contact form on this site. Client work runs through Upwork, whose terms restrict exchanging direct contact details off the platform, so the Upwork profile is the way in. The contract and the payment live there too.
