flang.dev Cookie Policy
This site does not set any cookies (one exception below). The effect is that it will forget your login when you reload the page, so the user experience may suffer a bit.
The playground which is available for registered users is based on openvscode-server. The playground sets a cookie called vscode-tkn with value "NO_TOKEN". This is because of technical necessity. Since the value is NO_TOKEN for everyone it can not be used for user tracking purposes. Additionally openvscode-server uses IndexedDB for remembering all kinds of settings.
