What this actually means

bbc.com contacted catalogued Google domains during this visit.

1 distinct catalogued tracking-service entity recorded responses across 13 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.

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; severity reflects fixed reference thresholds, not measured population percentiles. The request log, domain table, and methodology remain below for verification.

137 requests observed in one controlled visit.

Worth checking

17 of 136 requests the engine evaluated matched Brave Shields filter lists

17 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 5 request rows in this visit.Show matched requests

Context

This GPC comparison supports no comparable delta

The pair did not record the network egress region for both visits, and an unrecorded condition never counts as matching.

The raw request logs of both visits remain below for transparency, but the diff between them supports no claim about what the compared condition changed.

1 disqualifying condition named by the report's claim policy.

Worth checking

1 first-party DNS alias matched tracking checks

1 resolved target matched Brave filter lists; those matches do not identify the operators.

The scanner followed DNS CNAME chains from first-party subdomains and checked resolved targets against the service catalog and Brave filter lists. These matches do not establish a request's purpose, profiling, or an intent to conceal tracking. A filter-list match alone is not a verified service identity or proof of tracking.

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

Google 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 advertising. This scan could not identify 9 of the 13 third-party hosts recorded here, so it cannot say who operates them. That is a limit of identity coverage, not evidence about the site. The role taxonomy leaves at least one catalog category unclassified for these identified services and assigns none a tracking-related role, so they are not counted as tracking-related: Optimizely.

Context

Requests were dispatched to catalogued major-platform domains

This visit dispatched requests to catalogued domains for Google.

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.

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

Context

Third-party cookies were present

3 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.

17 cookies total in this report.Modest third-party cookies count.

Context

Input-monitoring signal involving a script from another domain

Listener coverage that could observe typing-related input events was registered through call chains that included a script served from another registrable domain, whose operator this scan did not establish.

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, 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, so the card 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.

216 interaction-listener registrations with https://cdn.tinypass.com/, https://static.files.bbci.co.uk/ and https://*.dotmetrics.net/ in the registration call chain and 82 input-listener registrations with https://static.files.bbci.co.uk/ in the registration call chain

Nothing observed

No fingerprint-like API calls observed

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

This is an observation layer, not proof that fingerprinting is impossible.

0 API families recorded.

GPC Comparison

GPC off and GPC on: two visits, no comparable metric delta

GPC off: 4,214msGPC on: 4,288ms
No metric deltas are comparable across these two visits, so none are shown.
  • Request, cookie, and storage deltas (each visit's own evidence still renders below): The pair did not record the network egress region for both visits, and an unrecorded condition never counts as matching.
  • Catalog-matched request and entity deltas (each visit's own evidence still renders below): The pair did not record the network egress region for both visits, and an unrecorded condition never counts as matching.
  • Other detector and causal-path deltas (each visit's own evidence still renders below): The pair did not record the network egress region for both visits, and an unrecorded condition never counts as matching.
  • The Shields-number delta (each visit's own evidence still renders below): The pair did not record the network egress region for both visits, and an unrecorded condition never counts as matching.
  • Fingerprinting deltas (each visit's own evidence still renders below): At least one visit did not complete the fingerprint measurement, so no exact cross-visit delta is shown.
  • Ad-pixel deltas (each visit's own evidence still renders below): At least one visit did not complete the pixel measurement, so no exact cross-visit delta is shown.

Measurement limits

4 conditions affect how this evidence reads

Both visits

  • Each visit in this report is one automated, headless Chromium visit from a fixed en-US / UTC profile, with no scrolling, clicking, or consent interaction. Sites can behave differently for real users, browsers, regions, accounts, or network locations.
  • Counts are a lower bound: trackers that load only after interaction or consent are not observed; Service Workers are blocked, and Web Worker or WebSocket traffic may be incomplete. Service labels use a US-biased hand-curated catalog, so regional services may be under-labeled. Cookie and storage figures are an end-of-visit snapshot, with storage keys read from the top frame only.
  • Resolved 1 first-party subdomain that is a CNAME alias for a third-party tracker (CNAME cloaking), which request-URL matching alone would miss.
  • Read the site's privacy policy (https://www.bbc.com/{seg}/privacy-policy) and compared its text against this visit's observed behavior. Policy checks are an automated text match with the matched sentences quoted, not a legal reading.

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. 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 .
