Privacy policy

Last updated: August 12, 2026

This policy explains how the Hydra project handles information when you visit the Hydra website at hydra.cc.

Information collected​

The website does not require an account and does not ask you to provide personal information directly.

Like most websites, our hosting and network providers may process routine technical information needed to deliver, secure, and maintain the site. This may include your IP address, browser and device type, requested pages, the date and time of a request, and the referring page.

Google Analytics​

We use Google Analytics 4 to understand, in aggregate, how the website and its documentation are used. Its default measurements include page and session activity, approximate location, and browser and device information. Google Analytics may set first-party cookies, including _ga, to distinguish users and sessions.

Google Analytics uses IP addresses during collection to derive approximate location information. Google states that IP addresses are discarded before the data is logged in Google Analytics. We do not use Google Analytics to identify individual visitors or for advertising, and we do not intentionally send names, email addresses, or other directly identifying information to it.

Google processes Analytics data under its own terms and privacy practices. For more information, see Google's explanation of how it uses information from sites that use its services and the Google Privacy Policy.

Other service providers and external sites​

The website is delivered using Cloudflare and GitHub Pages, and its search feature is provided by Algolia. These providers may process technical request or search information under their own privacy policies. The website also links to external sites. Their privacy practices apply when you visit them.

Your choices​

You can block or delete cookies using your browser settings. Google also offers a Google Analytics opt-out browser add-on. Blocking cookies or analytics may not prevent processing that is necessary to deliver or secure the website.

Data retention​

Analytics event data is retained according to the retention settings of the Hydra Google Analytics property. Aggregated reports that do not identify individual visitors may be retained for longer. Other providers retain information according to their own policies.

Changes to this policy​

We may update this policy when the website or its services change. We will update the date at the top of this page when we do.
