cut short: the scanner's search for a privacy-policy link did not cover every link on the page, so privacy-policy findings are incomplete; derived from status and warnings

Evidence quality

This report is built on an incomplete visit

Incomplete evidence: evidence was cut short before completion (the scanner's search for a privacy-policy link did not cover every link on the page, so privacy-policy findings are 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

paypal.com recorded 9 fewer third-party requests in the visit configured for Brave-list blocking.

The visit with no blocking made 126 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 9 fewer third-party requests. The blocker directly stopped 29 requests; the remaining difference may include follow-on requests that never started once their sources were blocked, plus run-to-run variance.

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 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.

126 requests observed in one controlled visit.

Worth checking

14 requests matched Brave Shields filter lists

14 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.

Not flagged

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 9 fewer third-party requests and 1 fewer tracking-related service request.

Services only seen in the unblocked visit: Google. The blocking visit's engine directly blocked 29 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.

Context

Privacy-policy cross-check not established

The page this scan read as the privacy policy held 1,978 characters of text, short enough to be the page before its policy loaded, so no policy text was compared against this visit's evidence. That is a limit of the automated check, not a finding about the site either way.

The scanner that recorded this visit read a policy page a fixed second after it began loading. Some pages render their policy later, and some had requests refused by the scan's own traffic budget, so a short read can be the page around a policy that never arrived. Company mentions and policy statements recorded from it are not used; later scanner versions wait for the page to settle and withhold such a read.

Page recorded as the policy: https://www.paypal.com/{seg}/privacy/{seg} (1,978 characters of text); no policy text compared.

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. This scan could not identify 3 of the 6 third-party hosts recorded here, so it cannot say who operates them. That is a limit of identity coverage, not evidence about the site.

114 cross-site requests across 6 third-party hosts.At or above the median for third-party domains across the 88 sites measured for this metric. Modest distinct tracking-service entities count.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.

1 request to these platforms.Show catalog-matched requests

Not flagged

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.

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.

15 cookies total in this report.At or above the median for third-party cookies across the 88 sites measured for this metric.

Context

Input-monitoring signal involving a script from another domain

Listener coverage that could observe typing-related input events was registered through call chains that included a script served from another registrable domain, whose operator this scan did not establish.

This is a behavioral instrumentation signal from listener registration, stack-attributed script origins, and known-vendor requests: it shows the page was instrumented to observe interaction, not that anything was transmitted. Stack attribution records the script origins present in the bounded registration call chain; a cross-site origin in that chain does not by itself establish that the cross-site script registered the listener, because first-party code can register its own listeners through a helper served from elsewhere. A different registrable domain is also not by itself a different operator: sites commonly serve their own scripts from a separate asset domain, so the card says third party only when the catalog or reviewed ownership attributes an origin to another organization. On scanners that run the active keystroke-capture probe, actual transmission is tested separately (a synthetic value is typed, never real input, and no typed values are collected); treat this card as a review prompt rather than proof.

274 interaction-listener registrations with https://www.paypalobjects.com/ in the registration call chain and 442 input-listener registrations with https://www.paypalobjects.com/ in the registration call chain

Context

Fingerprint-like browser APIs were called

4 high-entropy API calls appeared in the instrumentation log.

These calls can be legitimate (charts, graphics, media), so the count is observational, not a severity score, and it excludes Web and Service Workers. Top calls: webgl.getParameter.UNMASKED_RENDERER_WEBGL and webgl.getParameter.UNMASKED_VENDOR_WEBGL.

2 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. 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.

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 .
