When using Cloudinary's service to deliver assets to your website or application users, cookies are not set or used by us.
Cookies on asset delivery requests
If you're seeing that requests from your browser to "res.cloudinary.com" or "<your cloud>-res.cloudinary.com" are including one or more cookies, that is likely because the cookies were set in your browser during a previous visit to our website or Media Library and because the cookie was set in a way that sends it on requests to all subdomains of cloudinary.com.
Where such asset delivery requests are received by us and contain cookies, the values are ignored, are not stored, and do not affect your account's behaviour.
If you clear all cookies for cloudinary.com and then access a site which is using Cloudinary images, you should see that no cookies are set by those asset requests.
Please note that it's also possible depending on your plan to deliver assets via a subdomain of your own site, in which case any cookies sent with your asset delivery requests will be those scoped to your own domain, rather than to Cloudinary.com: https://cloudinary.com/documentation/advanced_url_delivery_options#private_cdns_and_cnames
