What this actually means

linkedin.com contacted catalogued LinkedIn domains during this visit.

1 distinct catalogued tracking-service entity recorded responses across 3 cross-site domains. A catalog match identifies the service domain, not why the request occurred or what it carried. It also looks like keyboard-input listeners were registered through a call chain that included a cross-site script and 3 browser-fingerprinting heuristics matched.

Worth checking

Bottom line: this visit has review-worthy signals

The scan observed signals a non-expert should not have to decode from raw request tables.

The cards below translate the evidence into plain language. Where a measured distribution exists, severity ranks this visit against percentiles from this report's cohort, with each percentile card naming its metric-specific measured-site denominator; otherwise it uses fixed reference thresholds. That cohort is drawn from a curated set of popular, mostly commercial sites, not a random sample of the web. The request log, domain table, and methodology remain below for verification.

42 requests observed in one controlled visit.

Context

2 requests matched Brave Shields filter lists

2 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.

The hand-curated service catalog separately matched 28 request rows in this visit.Show matched requests

Low signal

No change observed in the Brave-list blocking attempt

The blocking visit ran with the scanner configured to apply Brave's ad-block engine and default Shields filter lists. It was a simulation in this scanner's browser, not a live Brave-browser visit, and application was not verified. Compared with the unblocked visit, it showed no change in the comparable metrics (third-party requests, third-party cookies and tracking-related service requests).

The blocking visit's engine directly blocked 2 requests. Ad rotation, experiments, or caching between the two visits can offset or outweigh what blocking removed, which is how totals can hold steady or rise despite direct blocks. A single paired comparison can also reflect run-to-run variance (ad rotation, caching, experiments), so treat this as no observed difference for this pair of visits, not evidence that blocking removes nothing.

Context

Privacy policy read; it made no statement this scan can check

None of the statements this scan knows how to check appear in the policy text, so nothing was compared against this visit's evidence (1 of 1 observed tracking company named in the policy). That is a limit of the automated check, not a finding about the site either way.

Statements checked automatically: blanket no-cookie claims, third-party-cookie claims, and combined do-not-sell-or-share claims against advertising-pixel identifier fields. Global Privacy Control claims are never checked against request counts, which cannot show whether selling or sharing stopped.

Context

Catalogued service domains recorded responses during this visit

LinkedIn 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. This scan identified an operator for every one of the 3 third-party domains recorded here using catalog, consent-platform, reviewed-ownership, and CNAME evidence.

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.

28 requests to these platforms.Show catalog-matched requests

Not flagged

No Google Analytics observed

This visit did not contact Google Analytics.

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

No google-analytics.com or googletagmanager.com requests.Show catalog-matched requests

Not flagged

No third-party cookies observed

The automated visit did not observe third-party cookies.

This does not prove the site never uses cookies; it means this visit did not observe third-party cookies.

8 cookies total in this report.No third-party cookies observed.

Context

Input-monitoring signal involving a third-party script

Listener coverage that could observe typing-related input events was registered through call chains that included a third-party script.

This is a behavioral instrumentation signal from listener registration, stack-attributed script origins, and known-vendor requests: it shows the page was instrumented to observe interaction, not that anything was transmitted. Stack attribution records the script origins present in the bounded registration call chain. A cross-site origin in that chain does not by itself establish that the cross-site script registered the listener. That is because first-party code can register its own listeners through a helper served from elsewhere. A different registrable domain is also not by itself a different operator: sites commonly serve their own scripts from a separate asset domain. The card therefore says third party only when the catalog or reviewed ownership attributes an origin to another organization. On scanners that run the active keystroke-capture probe, actual transmission is tested separately (a synthetic value is typed, never real input, and no typed values are collected). Treat this card as a review prompt rather than proof.

Session-recording listener coverage: 139 interaction-listener registrations with https://static.licdn.com/ in the registration call chain. Input-monitoring listener coverage: 21 input-listener registrations with https://static.licdn.com/ in the registration call chain.

Worth checking

Behavioral fingerprinting heuristics matched

3 behavioral heuristics matched: Offline audio rendering heuristic, Canvas fingerprinting heuristic and WebRTC peer-connection probing.

These heuristics look for behavior patterns such as canvas readback after drawing, repeated canvas font measurement, WebGL entropy reads, offline audio rendering, or WebRTC peer-connection setup. They are review prompts for this visit, not proof of cross-site identity tracking.

Offline audio rendering heuristic: 1 offline render with audio.OfflineAudioContext.createDynamicsCompressor, audio.OfflineAudioContext.createOscillator and audio.OfflineAudioContext.startRendering. Canvas fingerprinting heuristic: 1 canvas matched; reads: canvas.toDataURL. WebRTC peer-connection probing: 1 peer connection with 1 data channel, 1 offer, and 1 local description.

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. 17 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 14 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. A study has been recorded for pixel-events and does not support a published rate under the current build. How detector accuracy is measured.

Severity percentiles come from this report's exact schema, methodology, tracker-catalog, ServiceRole-taxonomy, metric-contract, producer, and Global Privacy Control cohort. Each percentile card's measured sites are among 99 sites with a successful load across all cohorts. Other methodologies, request-capped visits, and post-choice consent visits are excluded from each card's denominator, while failed or block-page attempts are outside that coverage.

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 .
