What is stored while you read.
The site sets no cookies of its own; aggregate measurement runs through Google Analytics under Google’s terms. Here is what is actually stored while you use this site.
Cookies
This site sets none of its own. Google Analytics, used for aggregate traffic measurement, may store identifiers in your browser according to Google’s own terms; the site itself writes no cookie and reads none back.
Browser storage
The playground keeps your current query in memory for the length of the visit. It is not written to local storage, not written to a cookie, and not sent anywhere. Reloading the page returns it to the first sample.
Third parties
Two third-party services are involved in reading this site: the webfont loaded from Google Fonts, and the Google Analytics measurement tag. Neither is used for advertising.
If this changes
If what is stored ever changes, this page changes in the same commit that changes it. That is a rule about how this repository works, not a promise made elsewhere.
