Authorized uses


Design for Privacy


Tracking Preference Expression (DNT)


Tracking Preference Expression (DNT) (external link) W3C Working Group Note

  • DNT: 1 HTTP Request Header field value
  • navigator.doNotTrack DOM property: undefined
  • .well-known JSON file
      "tracking": "!",
      "qualifiers": "sd",
      "compliance": [
      "controller": ["/about#me"],
      "same-party": [
      "audit": [
      "policy": "/privacy",
      "config": "/.well-known/clear-site-data/wildcard"

Matching the above "tracking" and "qualifers" properties, in response to a DNT: 1 HTTP Request Header, this site sends a Tk HTTP Response Header with a Tracking Status Value (TSV) of Under Construction (!) followed by TSV-extensions of Security(s) and Debugging(d): Tk: !sd.
