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.

What this actually means

wikipedia.org's completed measurements recorded no listed activity, but the privacy-policy check did not apply to this page.

Nothing observed

Bottom line: few review signals in this visit

The automated visit did not observe known third-party services, third-party cookies, or instrumented fingerprint-like calls.

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.

6 requests observed in one controlled visit.

Nothing observed

No requests matched Brave Shields filter lists

No requests matched the default filter lists of Brave Shields, the ad and tracker blocker built into the Brave browser.

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 0 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.

Nothing observed

No known services matched

This scan did not match any third-party domains to the service catalog or another identity source.

No known operator or catalog entity was matched.

0 cross-site requests across 0 third-party hosts.No third-party domains observed.Show third-party requests

Nothing observed

No requests to major-platform domains were recorded

No requests to catalogued Google, Meta, TikTok, X, Microsoft, LinkedIn, or Pinterest domains were observed in this visit.

Major-platform domains were not observed in this single passive visit; interaction-gated requests could still load for real users.

0 cross-site domains seen overall.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

Nothing observed

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.

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

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.

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 .
