浏览器指纹:画像与证据Browser fingerprint, with the evidence

看看网站能读到哪些信号,而不是判断你是谁。点击带点状下划线的句子,查看本次真实读数与依据。See the signals websites can read—not a judgment about who you are. Tap any highlighted sentence to inspect its measured evidence.

默认本地 · 无广告与遥测Local by default · no ads or telemetry

网站眼里的你You, as a website might see you

句子会区分报告值、UA 线索与粗略估计。点击查看确切读数;桌面悬停也会提示来源。缺少证据时保留未知,不用猜测补齐。Sentences use reported, inferred, or coarse evidence. Tap to inspect the exact reading; on desktop the hover hint names its source. Missing data stays missing.

可选检测与隐私选项Optional probes & privacy controls

打开页面时仅自动读取本地基础信号;可选组初始关闭。渲染按钮会启用 Canvas、GPU、静默离线音频、字体度量及 DOM / SVG;不请求相机、麦克风、地理定位或本地字体权限。Basic readings start locally when this page opens. Optional groups are off initially. The rendering button enables Canvas, GPU, silent offline audio, font metrics and DOM/SVG; no camera, microphone, geolocation or local-font permission is requested.

选择可选组后点击刷新。字宽差异只是候选,不是字体清单;动画帧节奏不代表已验证的显示器刷新率。除非主动导出,结果只留在此标签页。Choose optional groups, then Refresh. Font differences are candidates—not a font inventory; frame cadence is not a verified display refresh rate. Everything remains in this tab unless you explicitly export it.

本次本地观察摘要Local observation digest

对列明的本地观察输入计算 SHA-256。它不是身份、群体唯一性估计、跨站标识或抗追踪评分。浏览器设置、字体、权限、渲染及所选检测项变化都可能改变摘要;服务器对照数据不计入。SHA-256 of the listed local observation inputs. It is not an identity, population-uniqueness estimate, cross-site identifier or tracking-resistance score. Browser settings, fonts, permissions, rendering and selected probes can change it. Server comparison data is excluded.

一致性观察,不是安全结论Consistency, not a verdict

可选:同源对照 ↓Optional same-site comparison ↓

一致仅说明现有报告一致。差异可能有正常原因,不证明欺骗、篡改、代理或 VPN。明确启用下方同源对照前,联网比较始终标记为未测试。Agreement only means the available reports agree. Differences can be legitimate; they do not prove lying, tampering, a proxy or VPN. Network comparisons remain “not tested” until you explicitly enable them below.

渲染证据Rendering evidence

主动启用后,这里展示实际本地输出,不使用示意图冒充。浏览器、图形栈和隐私设置不同,图像与摘要也可能不同。These are actual local outputs when enabled—not stock previews. Different browsers, graphics stacks and privacy settings can produce different images and hashes.

可选:与本站请求视角对照Optional: compare with this site’s request view

只有点击此处按钮才请求既有同源 /api/request-environment 端点。托管平台会看到这次独立 fetch 的连接 IP 和白名单请求头。不使用第三方 IP API,不新增服务、应用日志或存储;托管平台仍可能保留访问日志。Only this button requests our existing same-origin /api/request-environment endpoint. The host sees the connection IP and allowlisted headers of that separate fetch. No third-party IP API, new service, application logging or storage is added. Hosting-provider access logs may still exist.

仅当 Cloudflare 请求上下文实际提供时,才显示国家 / 地区、时区和 ASN。它们是粗略平台报告,不代表国籍、精确位置或独立核验的网络归属。缺少字段时保持不可用。Country, time zone and ASN appear only if actually supplied by Cloudflare’s request context. These are coarse provider reports, not nationality, precise position or independent proof of network ownership. Missing fields stay unavailable.

详细读数Detailed readings

不作身份认定;不从语言推断族裔 / 国籍,不从字体推断职业 / 年龄,不从时区差异判断 VPN。刻意区分不支持、被限制、未提供、未测试与已停止。No identity claim. No ethnicity/nationality inference from language. No occupation/age inference from fonts. No VPN verdict from a time-zone mismatch. “Unsupported”, “restricted”, “unavailable”, “not tested” and “stopped” are deliberately distinct.
