What Are Cookies

什么是 Cookie

Some cookies are set by us, and some by trusted third-party services (such as analytics or WhatsApp). Some last only for your visit ("session" cookies) and some remain until they expire or you delete them ("persistent" cookies). We group them into four kinds below.

部分 Cookie 由我们设置，部分由可信赖的第三方服务设置（例如分析工具或 WhatsApp）。有些仅在您本次访问期间有效（"会话" Cookie），有些则会保留至到期或被您删除（"持久" Cookie）。下文将它们分为四类说明。

Essential Cookies

必要 Cookie

These keep the website working — for example remembering your language choice (English or 中文) and keeping pages secure. The site cannot function properly without them, so they cannot be switched off.

这类 Cookie 维持网站的正常运作——例如记住您的语言选择（英文或中文）并保障页面安全。没有它们网站将无法正常运作，因此无法关闭。

Analytics Cookies

分析 Cookie

These help us understand, in aggregate, which pages are read, how long people stay, and what content is most useful — for example through Google Analytics. The data is anonymised and used only to improve our content and the site experience.

这类 Cookie 帮助我们从整体上了解哪些页面被阅读、读者停留多久、哪些内容最有价值——例如通过 Google Analytics。相关数据已匿名化，仅用于改进我们的内容与网站体验。

Marketing Cookies

营销 Cookie

If enabled, these (such as the Meta Pixel) help us measure whether our educational content and any advertising reach the right audience, and show relevant content to people who have visited us. We use them only to improve relevance — never to sell your data.

如已启用，这类 Cookie（例如 Meta Pixel）帮助我们衡量教育内容与广告是否触达合适的受众，并向曾访问我们的用户展示相关内容。我们仅用其提升相关性——绝不出售您的数据。

Preference Cookies

偏好 Cookie

These remember choices you make so the site feels consistent next time — such as your language preference being saved between visits.

这类 Cookie 记住您所做的选择，让您下次访问时体验一致——例如在多次访问之间保存您的语言偏好。

Managing & Disabling Cookies
