Evidence quality

This report is built on an incomplete visit

Incomplete evidence: evidence was cut short before completion (the in-page fingerprint observer could not read every frame, so the fingerprinting evidence is incomplete). Counts for the affected evidence are lower bounds; families that completed carry only their ordinary limits. The evidence receipt states the exact per-visit quality.

What this actually means

bing.com recorded 16 fewer third-party requests in the visit configured for Brave-list blocking.

The visit with no blocking made 372 requests; the visit configured to apply Brave's ad-block engine and default Shields filter lists (a simulation in this scanner's browser, not a live Brave-browser visit) recorded 16 fewer third-party requests. The blocker directly stopped 21 requests; the remaining difference may include follow-on requests that never started once their sources were blocked, plus run-to-run variance.

Review-worthy

Bottom line: this visit has review-worthy signals

The scan observed signals a non-expert should not have to decode from raw request tables. Some detector evidence was incomplete; each affected detector card states its own retained or unavailable scope, while completed request, cookie, and storage measurements keep their recorded exactness.

The cards below translate the evidence into plain language. Where a measured distribution exists, severity ranks this visit against percentiles from the report's exact schema, methodology, tracker-catalog, ServiceRole-taxonomy, metric-contract, producer, and Global Privacy Control cohort, with each percentile card naming its metric-specific measured-site denominator (among 98 sites with a successful load across all cohorts; other methodologies, request-capped visits, and post-choice consent visits are excluded from this denominator, while failed or block-page attempts are outside that coverage), a curated set of popular, mostly commercial sites, not a random sample of the web, and otherwise uses fixed reference thresholds. The request log, domain table, and methodology remain below for verification.

372 requests observed in one controlled visit.

Worth checking

22 requests matched Brave Shields filter lists

22 requests matched the default filter lists of Brave Shields, the ad and tracker blocker built into the Brave browser, while loading normally.

Computed with Brave's own ad-block engine and default filter lists in classification mode: matched requests were not blocked by the scanner and remain in this report's observed request counts. Matching shows what Shields would target on this visit's traffic; an actual Shields visit blocks these and also prevents their follow-on requests, so this number is neither a measured block count nor the total effect.

Nothing observed

Lower values observed across comparable metrics in the Brave-list blocking attempt

With the scanner configured to apply Brave's ad-block engine and default Shields filter lists (a simulation in this scanner's browser, not a live Brave-browser visit; application was not verified), this paired visit showed 16 fewer third-party requests, 7 fewer third-party cookies and 2 fewer tracking-related service requests.

Services only seen in the unblocked visit: LinkedIn and Taboola. The blocking visit's engine directly blocked 21 requests; the remaining difference may include follow-on requests that never started once their sources were blocked. A single paired comparison can also reflect run-to-run variance (ad rotation, caching, experiments), so treat this as an observed difference, not a measured blocking rate.

Context

Catalogued service domains recorded responses during this visit

LinkedIn and Taboola appeared in the request log.

A catalog match identifies a maintainer-reviewed service/domain mapping; it does not establish why an individual request occurred, what it carried, or whether profiling happened. Functional catalog labels include social / advertising pixel and advertising / recommendations. This scan could not identify 10 of the 12 third-party hosts recorded here, so it cannot say who operates them. That is a limit of identity coverage, not evidence about the site.

118 cross-site requests across 12 third-party hosts.At or above the median for third-party domains across the 88 sites measured for this metric. Modest distinct tracking-service entities count.Show third-party requests

Context

Requests were dispatched to catalogued major-platform domains

This visit dispatched requests to catalogued domains for LinkedIn.

The domain matches identify services, not the requests' purpose, payload, or whether any profile linking occurred.

1 request to these platforms.Show catalog-matched requests

Nothing observed

No Google Analytics observed

This visit did not contact Google Analytics.

Neither Google Analytics nor its remarketing sync was observed in this visit.

Review-worthy

Third-party cookies were present

18 third-party cookies showed up during the visit.

The scanner observed cookie metadata whose domain crossed the scanned site's registrable-domain boundary. This report does not retain cookie values or partition keys, so it does not establish whether a cookie was a persistent identifier or could recognize a visitor across sites.

41 cookies total in this report.At or above the 90th-percentile mark for third-party cookies across the 88 sites measured for this metric.

Context

Incomplete evidence: No fingerprint-like API calls observed in retained evidence before collection stopped

The scan did not observe the instrumented high-entropy browser APIs.

This is an observation layer, not proof that fingerprinting is impossible. Evidence collection was cut short, so this covers only what was recorded before the cutoff.

Retained incomplete evidence includes 0 API event records; no exact API-family total is available.

Recorded provenance is self-reported measurement metadata, not a cryptographic attestation. The public versioned report JSON contains the retained public evidence; see the methodology for interpretation and retention limits.

This report covers what the scanner measures, not everything a site can do. 16 browser surfaces are not instrumented at all (Every page except the one that was scanned; Anything that only loads after scrolling or interaction; Why a request happened, as a causal chain; and 13 others), 3 capabilities are declined by policy, and 3 are outside what any single visit can see. Their absence from this report is not evidence that they did not occur. Read the published coverage boundary.

Detector accuracy is unmeasured. No calibration study currently publishes a precision or recall for the detectors on this page, so a detector match here is a recorded observation, not a calibrated classification. How detector accuracy is measured.

Approved use boundary: This report is investigative evidence that requires independent corroboration. It is not a standalone legal determination and not the sole exhibit in a legal proceeding. Recorded in this project's release manifest on 2026-08-02.
