This policy explains what third-party services we use, what data they collect, and how you can control it.

- Country-level location (not precise location)

This data is aggregated and anonymous. No personally identifiable information is collected. Google's privacy policy →

Firebase Hosting
This site is hosted on Google Firebase. Firebase may log basic request data (IP address, browser type, timestamp) for security and performance purposes. This data is not used for advertising and is governed by Google's privacy policy.
Cookies
We use the following cookies:
The first two cookies (units and theme) are set by this site and contain no personal information — only your display preferences.
The remaining cookies are set by Google and are governed by Google's cookie policy.
