Evidence quality

This report is built on an incomplete visit

Incomplete evidence: evidence was cut short before completion (the in-page fingerprint observer could not attribute every event listener to the script that registered it, 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

capitalone.com recorded 213 fewer third-party requests in the visit configured for Brave-list blocking.

The visit with no blocking made 378 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 213 fewer third-party requests. The blocker directly stopped 20 requests; the remaining difference may include follow-on requests that never started once their sources were blocked, plus run-to-run variance.

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 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 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 99 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.

378 requests observed in one controlled visit.

Worth checking

216 requests matched Brave Shields filter lists

216 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 107 request rows in this visit.Show matched requests

Nothing observed

Lower values observed across comparable metrics in the Brave-list blocking attempt

With the scanner 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; application was not verified), this paired visit showed 213 fewer third-party requests, 5 fewer third-party cookies and 96 fewer tracking-related service requests.

Services only seen in the unblocked visit: Google and Adobe. The blocking visit's engine directly blocked 20 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), so treat this as an observed difference, not a measured blocking rate.

2 first-party DNS aliases matched tracking checks

Recorded DNS aliases resolve to catalogued tracking-related services: Adobe. 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

Tracking companies the privacy policy does not appear to name

Adobe was sent requests during this visit, but the policy text matched none of the names this scan knows that company by.

Policies often disclose vendor categories rather than company names, so an unnamed vendor is a transparency gap worth reviewing, not automatically a violation. Named in the policy: Google.

Policy at https://www.capitalone.com/privacy; 0 checkable statements matched; 1 of 2 observed tracking companies named in the policy.

Context

Catalogued service domains recorded responses during this visit

Google and Adobe 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 analytics / advertising. This scan could not identify 2 of the 14 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. 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.

91 requests to these platforms.Show catalog-matched requests

Nothing observed

Google Analytics present, no remarketing signal

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.

Worth checking

Third-party cookies were present

5 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.

27 cookies total in this report.At or above the 75th-percentile mark for third-party cookies across the 86 sites measured for this metric.

Worth checking

Behavioral fingerprinting heuristics matched

At least 3 behavioral heuristics matched in retained evidence: Canvas fingerprinting heuristic, Canvas font probing heuristic and WebRTC peer-connection probing.

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.toDataURL, 288 measureText calls across up to 78 fonts; measured text contents are not stored and 1 peer connection with 1 data channel, 1 offer, and 1 local description

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 2026-08-02.
