We collect almost nothing
所有数据不登录也全部可见；不放广告、不放第三方追踪脚本、不使用 Cookie 追踪个人。访问统计有两处：Cloudflare Web Analytics（无 Cookie），以及我们自己的计数脚本——它只把"哪一页被看了一次""从哪个域名跳来的"这类计数加一，不写 Cookie、不记 IP、不记浏览器指纹；为了区分同一次浏览，会在浏览器的会话存储里放一个标记，关掉标签页即消失。
Account (optional)
Signing in only unlocks personal features such as watches, alerts and corrections. We set and store no passwords. With GitHub sign-in we store your GitHub user ID, username, avatar URL and the email GitHub provides (for future alerts; lookups use only its hash). The session lives in a cookie named sinan_sid scoped to sinanlab.com and its subdomains, valid 30 days, server-readable only.
When you sign in with an email code, we store only the email address (to send codes and the alerts you switch on); the code itself is stored only as a hash and destroyed after 10 minutes. When you sign in with Google, we store the Google account id, display name, avatar URL and verified email.
What you leave on the site
Your watch list, alert settings and submitted corrections. Visible only to you and the site maintainers. To delete your account and all data, email [email protected]; we process it within 7 days.
Used only for alerts you subscribe to or enable; stored separately, not linked to browsing data; one-click unsubscribe anytime.
Outbound redirects
"Visit site" clicks pass through our redirect, which only counts clicks per site per day; no IP, browser identifier or referrer is recorded.
Your key
站上"用我的 Key 核实"的功能都在你的浏览器本地运行，Key 不上传、不落库、不经过我们的服务器。
另一种情况是站长为申请核验主动把一把小额 Key 发邮件给我们：这类 Key 只保存在我们的探测机本地，不进任何代码仓库、不出现在任何页面或数据文件里，只用于公开说明过的一致性探针与能力抽样；随时来信即可停用并删除。
写信给我们
寄到 [email protected] 的邮件会转发到维护者邮箱，同时在我们自己的数据库里留一份，用于处理纠错与核验申请；正文里出现的密钥、令牌一类凭据在入库前会自动打码。你可以来信要求删除你的邮件记录。
众测上传
命令行工具上传的跑分只含指标与硬件型号，不含图像、数据或密钥；为了防刷会记录一个由 IP 与浏览器标识算出的哈希值，无法还原成你的身份。
Statistics
The admin panel sees only counts without personal information: daily sign-ins, sign-ups, watches, outbound clicks.
