What is counted?统计哪些信息？

• Page views and returning visitors, all-time and per UTC day.累计与按 UTC 日汇总的浏览量和去重访客数。
• Page paths without queries or fragments; acquisition source categories or referrer hostnames, never full referrer URLs or search terms.不含查询参数和片段的页面路径；来源类别或来源网站域名，不存储完整来源网址或搜索词。
• Country and approximate location from Cloudflare, rounded to 1° map buckets. Raw IP addresses are not written to the analytics database.Cloudflare 提供的国家与粗略地域，地图位置取整到 1° 网格。原始 IP 地址不写入统计数据库。
• Page-load timing histograms by country: document first byte and page shown. These reports have no visitor identifier.按国家聚合的加载时间直方图，包括首字节和页面呈现耗时；此类报告不包含访客标识。

Only aggregate statistics are shown on the dashboard. This site's data is not combined with Analog Canvas or the personal homepage.统计页面只显示汇总数据，不与 Analog Canvas 或个人主页合并统计。

How long is it retained?保存多久？

• The host-only, HttpOnly vb_vid cookie contains a random visitor ID. It lasts one year from the first counted visit and is never renewed.仅限本域、HttpOnly 的 vb_vid Cookie 保存随机访客 ID，从首次计数起保留一年，访问时不会续期。
• The database keeps a SHA-256 hash of the ID and its last-seen day, not the raw ID. Hashes not seen for 366 days are deleted; all-time aggregate counts are retained.数据库保存 ID 的 SHA-256 哈希及最后访问日期，而非原始 ID。366 天未出现的哈希会删除，累计汇总计数保留。
• Finished days keep visitor counts, not their visitor hashes. The dashboard shows a 400-day traffic window and 30-day load-time summaries.已结束的日期只保留访客计数，不保留该日访客哈希。面板显示约 400 天流量及最近 30 天加载耗时汇总。

Choose not to be counted.你可以选择不被计数。

We honor Do Not Track and Global Privacy Control. You can also opt out here. This removes your visitor cookie and sets vb_optout for 13 months; past anonymous aggregate counts are unchanged.我们尊重 Do Not Track 和 Global Privacy Control。你也可以在这里退出统计：删除访客 Cookie，并用 vb_optout 保存偏好 13 个月；过去的匿名汇总计数不会改变。
