|Universal Analytics (Google)||_ga
|These cookies are used to collect information about how visitors use our website. We use the information to compile reports and to help us improve the website. The cookies collect information in an anonymous form, including the number of visitors to the website and blog, where visitors have come to the website from and the pages they visited.|
|Cloudflare||__cfduid||The cookie is used to identify individual clients behind a shared IP address and apply security settings on a per-client basis. For example, if the visitor is in a coffee shop where there are a bunch of infected machines, but the specific visitor’s machine is trusted (e.g. because they’ve completed a challenge within your Challenge Passage period), the cookie allows us to identify that client and not challenge them again. It does not correspond to any user ID in your web application, and does not store any personally identifiable information.|
|We embed videos from our official YouTube channel using YouTube’s privacy-enhanced mode. This mode may set cookies on your computer once you click on the YouTube video player, but YouTube will not store personally-identifiable cookie information for playbacks of embedded videos using the privacy-enhanced mode.
