Privacy Policy for Gammapy Websites

Effective Date: October 14th, 2024.
Last update: July 23rd, 2025.

Thank you for visiting our websites, gammapy.org and docs.gammapy.org. At Gammapy, we are committed to protecting your privacy and ensuring that your personal data is handled in a safe and responsible manner. This Privacy Policy explains how we collect, use, and protect any information obtained during your visit to our websites.

We use an open-source analytics platform called Matomo Analytics to collect anonymized information about how users interact with our websites. The data we collect includes:

• the pages you visit on our sites,
• the time spent on each page,
• your approximate location (based on anonymized IP addresses),
• the device and browser you use to access our sites.

Important: all data collected is strictly anonymized, and we do not collect any personally identifiable information (PII).

How do we collect data?

We have configured Matomo Analytics to prioritize your privacy:

• no Cookies: We do not use tracking cookies. This means we cannot track users across different browsing sessions or websites,
• anonymized IP Addresses: We anonymize your IP address by removing the last two bytes (e.g., 192.168.x.x). This makes it impossible to identify your specific location or device,
• no User Tracking: We do not assign unique user IDs, nor do we track individuals over time.

Why do we collect data?

We only use the collected data for the following purposes:

• to analyze overall website performance,
• to improve the structure, content, and functionality of our sites,
• to understand how visitors use our websites.

We do not use this data for any commercial or marketing purposes, and we do not share the data with third parties.

How do we protect your Data?

We take your privacy seriously and have taken the following steps to protect any data collected:

• all data is stored securely on our server at the AstroParticule & Cosmologie laboratory located in Paris, France, and is not accessible to third parties,
• we anonymize all data to ensure that no personally identifiable information is ever collected or processed,
• we do not combine the data we collect with any external databases or information.

Your privacy choices

Since we do not use cookies, there is no need to accept or manage cookie consent for analytics purposes. However, you can opt out of being tracked by our Matomo Analytics instance. See the instructions:

Third-party links

Our websites may contain links to external sites, such as documentation resources or partner organizations. We are not responsible for the privacy practices or content of these third-party sites. We encourage you to review their privacy policies before sharing any personal information with them.
