Thank you for reporting!

At a first glance, I'm not sure why it is not showing up, but I would also have expected it to be detected. Will need to dig deeper to understand what is going on.

Looking a sample of raw data, these are candidates for subdomains under which it operates:

  31351   "www.clarity.ms"
  19603   "c.clarity.ms"
   6471   "h.clarity.ms"
   6416   "i.clarity.ms"
   6415   "f.clarity.ms"
   6385   "e.clarity.ms"
   6280   "a.clarity.ms"
   6131   "j.clarity.ms"
   6051   "d.clarity.ms"
   4126   "b.clarity.ms"
    758   "g.clarity.ms"

Made some changes now. In March (with the next monthly update), we should see the effects.

@philipp-classen Thanks ! Does it means changes are made in the data processing pipeline or into the tracker signature database ?? (not sure of what is the product architecture as of today)

[philipp-classen]

@googleanalyticsresoneo It was an internal change (adding mappings), so unfortunately I cannot link to a diff. In the public data that we release begin of March, I would expected two changes:

• https://s3.amazonaws.com/data.whotracks.me/trackerdb.sql should have additional entries for Microsoft Clarity (currently it doesn't)
• There should be entries in the public computed data sets, which are also used for the WhoTrackMe web site.

With the March release of the February data, there MS Clarity is now detected:

The April release is out, which brought a slight release in reach. Overall the data looks stable, so I'm closing it now.
