This report has a reviewed clarification

SBL-CORR-2026-001: The historical input-probe disclosure overstates coverage. Unload-only transmissions were not reliably recorded. Focus and blur handlers could run, and per-field failures were not fully counted. These reports cannot establish absence of input transmission outside their retained observations.

Evidence quality

This report is built on an incomplete visit

Incomplete evidence: evidence was cut short before completion (the Worker instrumentation could not record every request, so the request 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.

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. Some activity evidence was also incomplete: request counts are retained lower bounds.

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.

at least 52 retained requests observed in one controlled visit.

Worth checking

at least 14 retained requests matched Brave Shields filter lists

at least 14 retained 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 at least 6 retained request rows in this visit.Show matched requests

Context

This Shields comparison is not conclusive

The "No blocking" visit reported GPC Worker capture loss, so its request evidence is incomplete. and The "Brave-list blocking" visit reported GPC Worker capture loss, so its request evidence is incomplete.

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.

2 disqualifying conditions named by the report's claim policy.Show matched requests

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. Evidence collection was cut short, so this covers only what was recorded before the cutoff.

Policy at https://creativecommons.org/privacy; 0 checkable statements matched; 1 of 1 observed tracking company named in the policy.

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 analytics / tag management and advertising. This scan identified an operator for every one of the 5 third-party domains recorded here using catalog, consent-platform, reviewed-ownership, and CNAME evidence.

at least 13 retained cross-site requests across at least 5 retained third-party hosts.Show third-party requests

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.

at least 6 retained requests to these platforms.Show catalog-matched requests

Context

Incomplete evidence: Google Analytics present, no remarketing signal in retained evidence before collection stopped

Google Analytics was observed, but no DoubleClick remarketing sync appeared in this visit.

Standard analytics collection was observed, without the stats.g.doubleclick.net advertising sync. Evidence collection was cut short, so this covers only what was recorded before the cutoff.

Google Analytics host observed; no stats.g.doubleclick.net request.Show catalog-matched requests

Context

Third-party cookies were present

1 third-party cookie 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.

4 cookies total in this report.

Worth checking

Canvas fingerprinting heuristic matched

1 behavioral heuristic matched: Canvas fingerprinting heuristic.

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.

1 canvas matched; reads: canvas.getImageData

Brave Shields Comparison

No blocking and Brave-list blocking: two visits, no comparable metric delta

No blocking: 5,867msBrave-list blocking: 5,654ms
These two visits do not support a side-by-side comparison, so no deltas are shown.
  • The "No blocking" visit reported GPC Worker capture loss, so its request evidence is incomplete.
  • The "Brave-list blocking" visit reported GPC Worker capture loss, so its request evidence is incomplete.

Each visit's own evidence still stands: use the “Evidence shown” switcher below to inspect either visit's tables, and both visits are in the downloaded JSON.

Measurement limits

8 conditions affect how this evidence reads

This report

  • Brave-list blocking comparison runs should be collected under matched crawl conditions, and the blocking run is a simulation with Brave's engine and default lists in this scanner's browser, not a live Brave visit. Differences can still reflect timing, experiments, cache state, consent state, or bot detection.
  • The two visits ran in randomized order; the "Brave-list blocking" visit ran first.

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.
  • This scan typed a synthetic test value into 1 form field (never submitting the form) to test whether typed input is captured and sent to third parties. The value is synthetic and is not stored. Requests the page sent during and after this typing, including any unload beacons, are part of the recorded request log and counts.
  • Read the site's privacy policy (https://creativecommons.org/privacy) 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.
  • The scan blocked or could not verify one or more Web Workers while applying the simulated GPC signal; request evidence may be incomplete.

Brave-list blocking visit only

  • Brave Shields block simulation was enabled; matching requests were aborted before loading and are not included in request totals.

How to use this report

Read the findings and measurement limits first, then inspect the evidence for each recorded visit. Comparisons include both visits, even where a difference cannot be interpreted.

Keep this PDF with its evidence package: the source JSON, correction context, export receipt and SHA256SUMS. The package preserves source bytes and the correction context at export time. Hashes check file consistency; they do not establish independent measurement accuracy or a signed attestation.

Request attribution map

Which actor each third-party request is attributed to, from the initiator the browser reported. Attribution, not causation: an initiator may itself have been told what to fetch, and requests with no reported initiator are not distinguished from ones fetched from several. Asterisks mark subdomain labels hidden for privacy.
Attributed requests
Incomplete
Not attributable
≥13
Third-party requests
≥13

No unique actor could be assigned to ≥13 of these requests. That includes requests for which the browser reported no usable initiator, and repeated URLs seen with conflicting initiators. This report does not distinguish those causes, so they are counted together rather than drawn.

The retained rows establish no useful floor for requests with one recorded actor. Request capture was incomplete, so every count is a lower bound and no coverage percentage is reported.

No retained third-party request has one recorded actor to draw. This is not evidence that no actor was involved: the visit may have reported no actor or several actors for the same request.

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 .
