Incomplete evidence: evidence was cut short before completion (the in-page fingerprint observer could not read every frame, so the fingerprinting 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
creditkarma.com recorded 95 fewer third-party requests in the visit configured for Brave-list blocking.
The visit with no blocking made 208 requests; the visit configured to apply Brave's ad-block engine and default Shields filter lists (a simulation in this scanner's browser, not a live Brave-browser visit) recorded 95 fewer third-party requests. The blocker directly stopped 7 requests; the remaining difference may include follow-on requests that never started once their sources were blocked, plus run-to-run variance.
The scan observed signals a non-expert should not have to decode from raw request tables. Some detector evidence was incomplete; each affected detector card states its own retained or unavailable scope, while completed request, cookie, and storage measurements keep their recorded exactness.
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.

Setup
Both visits used headless Chromium in a desktop window of 1440 × 980, with en-US language and UTC time zone. Both ran from a GitHub Actions Ubuntu runner; the network region was not recorded. Neither sent the Global Privacy Control (GPC) signal.
Visits
Two visits configured to differ in Brave-list blocking: No blocking and Brave-list blocking.
Interactions
No typing was recorded in either visit. No scrolling, clicking or consent interaction.
Outcome
Both visits completed, but some evidence in the No blocking visit was cut short.
What these visits could not see
Other pages on this site. Only the requested page's activity was recorded.
Signed-in visitors, other browsers and other regions. Both visits were automated, from a fixed en-US / UTC profile. Sites can behave differently for real users, browsers, regions, accounts, or network locations.
Anything that loads only after interaction or consent. Trackers that load that late are not observed, so counts are a lower bound.
Services the catalog does not name. Service labels use a US-biased hand-curated catalog, so regional services may be under-labeled.
Checks with incomplete evidence. In the No blocking visit only: advertising pixels, fingerprinting, session-recording signals, the typing test, CNAME cloaking, the consent banner and the privacy policy check. Each linked card states what was retained.

61 requests matched Brave Shields filter lists
61 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. This is Site Behavior Lab's list-based simulation, which applies every list to the site's own requests too. Brave's default Standard setting skips most of these lists for such requests, so its results can differ. Blocking can also prevent follow-on requests, so this number is neither a measured block count nor what a Brave visit would block.
The hand-curated service catalog separately matched 51 request rows in this visit.Show matched requests
Not flagged
Lower values observed across comparable metrics 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 95 fewer third-party requests, 18 fewer third-party cookies and 47 fewer tracking-related service requests.
Services only seen in the unblocked visit: Google, TikTok and Adobe, plus 6 others. The blocking visit's engine directly blocked 7 requests; the remaining difference may include follow-on requests that never started once their sources were blocked. A single paired comparison can also reflect run-to-run variance (ad rotation, caching, experiments). Treat this as an observed difference, not a measured blocking rate.

Requests were dispatched to catalogued service domains
Google, TikTok and Adobe, plus 7 others 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, advertising and social / advertising pixel. This scan could not identify 14 of the 32 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 assigns these additional services explicitly non-tracking operational, support, security, consent-management, or hosting roles: New Relic.
142 cross-site requests across 32 third-party hosts.At or above the 75th-percentile mark for third-party domains across the 91 sites measured for this metric. Elevated distinct tracking-service entities count (at or above the 6 reference threshold).Show third-party requests
Worth checking
Requests were dispatched to catalogued major-platform domains
This visit dispatched requests to catalogued domains for Google, Meta and TikTok, plus 2 others.
The domain matches identify services, not the requests' purpose, payload, or whether any profile linking occurred.
TikTok Pixel requests contained event labels during this visit.
Pixel decoding was incomplete for one or more request bodies, so whether other pixel requests carried advanced-matching identifier fields is unknown. Retained labels describe request contents, not verified user actions or successful delivery.
18 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.
53 cookies total in this report.At or above the 90th-percentile mark for third-party cookies across the 91 sites measured for this metric.

Offline audio rendering heuristic matched
At least 1 behavioral heuristic matched in retained evidence: Offline audio rendering 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.
Offline audio rendering heuristic: 1 offline render with audio.OfflineAudioContext.createAnalyser, audio.OfflineAudioContext.createDynamicsCompressor and audio.OfflineAudioContext.createOscillator, plus 1 other.

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.
