What this visit means

Unfamiliar terms are defined in the glossary
playwright-chromium

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.

The cards below translate the evidence into plain language; severity reflects fixed reference thresholds, not measured population percentiles. The request log, domain table, and methodology remain below for verification.

107 requests observed in one controlled visit.

Context

8 requests matched Brave Shields filter lists

8 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 8 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 4 fewer third-party requests and 8 fewer tracking-related service requests.

Services only seen in the unblocked visit: Google and Contentsquare. The blocking visit's engine directly blocked 5 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.

Signed per-metric differences between the two visits; nothing is summed across metrics.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 (2 of 2 observed tracking companies 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.

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

Context

Catalogued service domains recorded responses during this visit

Google and Contentsquare 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 session replay / behavior analytics. This scan could not identify 1 of the 11 third-party hosts recorded here, so it cannot say who operates it. That is a limit of identity coverage, not evidence about the site. Catalog labels include session-replay or behavior-analytics services: Contentsquare; the domain match alone does not prove that a recording occurred.

71 cross-site requests across 11 third-party hosts.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.

6 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.

10 cookies total in this report.Elevated third-party cookies count (at or above the 5 reference threshold).

Context

Session-replay vendor observed

Contentsquare appeared in the request log.

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.

known session-replay vendor(s): Contentsquare

Context

Fingerprint-like browser APIs were called

1 high-entropy API call 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.

1 API family recorded.

Brave Shields Comparison

No blocking → Brave-list blocking delta

No blocking: 7,215msBrave-list blocking: 7,028ms
Some deltas are not comparable across these two visits and are not shown.
  • Other detector and causal-path deltas (each visit's own evidence still renders below): v1 never recorded detector versions, so fingerprinting and pixel deltas cannot be proven to come from matching instrumentation.
  • The Shields-number delta (each visit's own evidence still renders below): The two visits measured different Shields quantities (filter-list matches vs engine-blocked requests), which must never share a delta.
  • Fingerprinting deltas (each visit's own evidence still renders below): At least one visit did not complete the fingerprint measurement, so no exact cross-visit delta is shown.
  • Ad-pixel deltas (each visit's own evidence still renders below): At least one visit did not complete the pixel measurement, so no exact cross-visit delta is shown.

Measurement limits

7 conditions affect how this evidence reads

This report

  • Brave-list blocking comparison runs should be collected under matched crawl conditions, and the blocking run is a simulation with Brave's engine and default lists in this scanner's browser, not a live Brave visit. Differences can still reflect timing, experiments, cache state, consent state, or bot detection.
  • The two visits ran in randomized order; the "No blocking" visit ran first.

Both visits

  • Each visit in this report is one automated, headless Chromium visit from a fixed en-US / UTC profile, with no scrolling, clicking, or consent interaction. Sites can behave differently for real users, browsers, regions, accounts, or network locations.
  • Counts are a lower bound: trackers that load only after interaction or consent are not observed; Service Workers are blocked, and Web Worker or WebSocket traffic may be incomplete. Service labels use a US-biased hand-curated catalog, so regional services may be under-labeled. Cookie and storage figures are an end-of-visit snapshot, with storage keys read from the top frame only.
  • This scan typed a synthetic test value into 1 form field (never submitting the form) to test whether typed input is captured and sent to third parties. The value is synthetic and is not stored. Requests the page sent during and after this typing, including any unload beacons, are part of the recorded request log and counts.
  • Read the site's privacy policy (https://www.stanford.edu/privacy) and compared its text against this visit's observed behavior. Policy checks are an automated text match with the matched sentences quoted, not a legal reading.

Brave-list blocking visit only

  • Brave Shields block simulation was enabled; matching requests were aborted before loading and are not included in request totals.

How to use this report

Read the findings and measurement limits first, then inspect the evidence for each recorded visit. Comparisons include both visits, even where a difference cannot be interpreted.

Keep this PDF with its evidence package: the source JSON, correction context, export receipt and SHA256SUMS. The package preserves source bytes and the correction context at export time. Hashes check file consistency; they do not establish independent measurement accuracy or a signed attestation.

No unique actor could be assigned to 71 of these requests. That includes requests for which the browser reported no usable initiator, and repeated URLs seen with conflicting initiators. This report does not distinguish those causes, so they are counted together rather than drawn.

71 third-party requests: 0 attributed to a single recorded actor, 71 not attributable.

No retained third-party request has one recorded actor to draw. This is not evidence that no actor was involved: the visit may have reported no actor or several actors for the same request.

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 .

Reports record one automated visit per condition; visits may be incomplete. Results describe these visits, not everything a site can do.
