 網站訪客的隱私對我們很重要，因此我們不會追蹤任何個人。 作為我們網站的訪客：
 
-- 不收集任何個人資訊
-- 瀏覽器中不會儲存 Cookie 等資訊
+- No personal information is stored

+You can view the data we collect on our [statistics](statistics.md) page.
+
+We run a self-hosted installation of [Umami](https://umami.is/) to collect some anonymous usage data for statistical purposes. The goal is to track overall trends in our website traffic, it is not to track individual visitors. All the data is in aggregate only, and no personal data is stored.
+
+The only data which is collected is data sent in a standard web request, which includes referral sources, the page you're visiting, your user agent, your IP address, and your screen resolution. The raw data is immediately discarded after statistics have been generated, for example if we collect your screen resolution as `1125x2436`, the only data we retain is "mobile device" and not your specific resolution.

+title: Traffic Statistics

+
+We self-host [Umami](https://umami.is/) to create a nice visualization of our traffic statistics, which are public at the link below. With this process:
+
+- Your information is never shared with a third-party, it stays on servers we control
+- Your personal data is never saved, we only collect data in aggregate
+- No client-side JavaScript is required
+
+Because of these facts, keep in mind our statistics may be inaccurate. It is a useful tool to compare different dates with each other and analyze overall trends, but the actual numbers may be far off from reality. They're _precise_ statistics, but not _accurate_ statistics.
