Privacy

This note explains how 51大事件 records visits and comments. Personal information is not sold.

Visit statistics

On the first page view, the browser stores a random visitor id in a cookie named vid, kept for about a year. It is used to count daily visits, active readers, and return visits over about 30 days. It does not contain a name, phone number, or account.

The server derives a country and broad region from the IP address so we can see where readers are. The raw IP is not written into articles and is not given to anyone other than an ad service when an ad is shown. Device type comes from the browser identifier, and the traffic source comes from the page that linked here.

The page may compute a short summary of browser traits. Only that summary is stored, so repeat visits by the same reader are not counted as many different people.

Comments

Commenting requires a reader identity. We store the nickname, the comment, and the time it was posted. The signed-in state is kept in a cookie named reader_session, which expires after about 30 days.

Comments are visible to other readers. Do not put a phone number, address, identity document, or anything else you do not want published into a comment.

Advertising

Some pages show third-party ads, such as Google ads. The ad service may set its own cookies or read device information to display and measure ads. That handling follows the ad service's own privacy notice.

Search engines

Visits from Google, Bing, and similar crawlers are logged separately. They are not counted as readers and do not receive a visitor id. The sitemap and robots.txt are public files meant for those crawlers.

Your choices

You can clear or block cookies in the browser. Visit counts then become coarser, and commenting may require signing in again.
