The short version: COSMOS does not collect any personal data. We have no accounts, no cookies, no tracking, and no analytics. You are completely anonymous when using this site.
COSMOS does not collect, store, process, or share any personal information about its visitors. There are no user accounts, no registration forms, no contact forms, no comment systems, and no newsletter sign-ups. We have no way of knowing who you are, where you are from, or what you have read on this site.
We do not use cookies of any kind — neither session cookies, persistent cookies, nor third-party tracking cookies. No data is written to your browser's local storage or session storage by this website.
COSMOS does not use any web analytics platform such as Google Analytics, Plausible, Fathom, or any equivalent service. We do not track page views, session duration, click patterns, referral sources, or any other behavioural data. Your browsing activity on this site is not recorded in any way.
COSMOS loads a small number of resources from third-party providers to function correctly. These are:
Google Fonts — We use Google Fonts to display the typefaces used on this site. When your browser loads a page on COSMOS, it makes a request to Google's servers to download the font files. Google may log this request as part of their standard server logging. You can review Google's privacy policy at policies.google.com/privacy.
YouTube (Google LLC) — The hero background video on COSMOS's homepage is embedded from YouTube. When you visit the homepage, your browser connects to YouTube's servers to stream the video. YouTube may collect data about this playback in accordance with their own privacy policy. You can review it at policies.google.com/privacy. COSMOS has no control over the data YouTube collects.
COSMOS may contain links to external websites such as NASA, ESA, Hubble Site, and other scientific resources. Once you click an external link and leave COSMOS, this privacy policy no longer applies. We are not responsible for the privacy practices of any external website and encourage you to review their policies individually.
COSMOS is designed as an educational resource suitable for all ages. Because we collect no personal data whatsoever, there are no special provisions required regarding children's privacy. No information is collected from any visitor, regardless of age.
If this privacy policy is ever updated, the revised version will be posted on this page with an updated date at the top. Given that COSMOS collects no data, changes to this policy are expected to be rare and minor. Continued use of COSMOS following any changes constitutes your acceptance of the revised policy.
If you have any questions about this privacy policy, you can reach the COSMOS team via the contact information provided on the main website. As we collect no personal data, there is no data to request access to or deletion of.
