Identified as Chrome (also Chromium Browser) ?Identity labels come from the community JA4+ database by FoxIO — applications observed with a JA4 fingerprint, not something this site measured. A JA4 identifies a TLS stack, so unrelated applications built on the same stack (notably the many Chromium-based browsers) legitimately share one: labels are a ranked distribution, never a verdict.Labels are loaded from a snapshot and cover only the JA4 family. Where a fingerprint page shows matches controlled captures, that is Thumbprint's own measured truth instead. More on methodology. — per the JA4+ database; JA4 is a TLS-stack fingerprint, so unrelated clients can share one.
Distinct clients per day (last 30 days, peak 85/day)
Distinct clients are counted by IP-hash per complete UTC day — unlike observation counts this is insensitive to one chatty client, but NAT merges clients and address rotation splits them.

Co-observed signals
Signals from other families seen in the same observation. A fingerprint spread thinly across many lower-layer signatures is a classic inconsistency signal.
