Session Context：一页网页能「看懂」你什么 Session Context: what one web page can learn about you

详细介绍Details

公开互动页：把浏览器在未授权前就能测到的指纹 / 头信息 / 存储与设备线索，先写成白话结论，再展开字段表；权限类能力单独列出且默认不索取。 A public interactive page that turns what a browser can measure before any permission prompt—fingerprints, headers, storage and device hints—into plain-English findings, then field tables; permission-gated APIs are listed separately and not requested by default.

适合学什么What to learn

• 游戏/互动 Game / interactive

  可直接玩或操作的教学游戏与 WebGL 演示。 Teaching games and WebGL demos you can play in the browser.

  带可运行示例的文档站与示例索引。 Doc sites and example indexes with runnable samples.

为什么推荐Why we recommend it 站点自述几乎所有值在浏览器内测、不落盘；两个需服务端暂记的演示会在页面标明。指纹熵数字引自公开研究，本站未复测。 The site claims nearly all values are measured in-browser and not written to disk; the two demos that need short server memory say so on-page. Entropy figures cite published studies and were not re-measured here.
