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.

What this actually means

creativecommons.org's retained request log includes catalogued Google domains.

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. This failed or incomplete evidence is not ranked against corpus percentiles; positive signals remain visible as lower bounds. 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.

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.

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

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. A study has been recorded for pixel-events and does not support a published rate under the current build. 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 .
