Visit analytics (Google Analytics 4)

Records the pages you view, where the visit came from, device and browser type, approximate region, and actions such as scrolling, clicking outbound links, using a contact option (sending an email, copying the WeChat ID, opening a QR code) and copying an article link. Only the type of action is recorded, never the email address or WeChat ID itself.
Sets two cookies, _ga and one starting with _ga_, to tell visits and sessions apart. They last up to 2 years.
In Google Analytics, event data linked to cookies is kept for 2 months and user-level data for 14 months; aggregated reports are not affected. Google Analytics 4 does not log or store IP addresses.
Analytics only shows which content is useful to readers and is not used for advertising; all advertising storage is turned off.

The site is hosted on Vercel and uses Vercel Web Analytics to count page views. It sets no cookies and is not affected by the analytics setting below.

When a page fails, the error, the page address (without query parameters) and the browser type are sent to Sentry so the problem can be fixed; about 10% of visits also report page load timing. Reports carry no user details, cookies, request headers or request bodies, and Sentry is set not to store IP addresses.

If your browser time zone is in Europe, a bar at the bottom of the page asks whether to allow analytics. Google Analytics is not loaded until you choose.
For visitors located in the European Economic Area, the UK or Switzerland by network address, analytics cookies are off by default. Google then only receives basic visit signals without cookie identifiers.
Analytics is on by default elsewhere. You can turn it off below at any time; Google Analytics then stops loading on this site and its cookies are deleted.
Your choice is stored in this browser’s local storage, and the site uses it to decide whether to load Google Analytics; when analytics is on, Google receives the matching consent status with its requests. Open tabs follow the same choice. You will need to choose again in another browser or after clearing site data.

Google, Vercel and Sentry may process data on servers outside your country or region. This site does not sell data or share it with any third party other than these providers.
