 The privacy of our website visitors is important to us, so we do not track any individual people. As a visitor to our website:
 
-- No personal information is collected
-- No information such as cookies are stored in the browser
+- No personal information is stored
 - No information is shared with, sent to or sold to third-parties
 - No information is shared with advertising companies
 - No information is mined and harvested for personal and behavioral trends
 - No information is monetized
 
+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.

 ## Data We Collect From Account Holders
 
 If you register for an account on one of our services, we may collect any information you provide us (such as your email, password, profile information, etc.) and use that information to provide you with the service. We never share or sell this data.

+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.
