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.

SBL-CORR-2026-002: The policy entity matcher did not recognize Amazon and Oracle under their catalog names. An unmentioned-entity result for Amazon Ads or Oracle Advertising is not reliable evidence that the policy omitted the company. Original policy text was not retained, so individual mention results cannot be reconstructed. Consult all clarification events for this report.

Review-worthy

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.

261 requests observed in one controlled visit.

Worth checking

119 requests matched Brave Shields filter lists

119 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 45 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 153 fewer third-party requests, 35 fewer third-party cookies and 40 fewer tracking-related service requests.

Services only seen in the unblocked visit: Google, Lotame and Amazon Ads, plus 6 others. The blocking visit's engine directly blocked 12 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

Tracking companies the privacy policy does not appear to name

Lotame, VWO and The Trade Desk, plus 5 others were sent requests during this visit, but the policy text matched none of the names this scan knows those companies 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.coolmathgames.com/{seg}; 0 checkable statements matched; 1 of 9 observed tracking companies named in the policy; policy mentions of Amazon Ads are unknown because the historical alias matcher was incomplete.

Review-worthy

Requests were dispatched to catalogued service domains

Google, Lotame and VWO, 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 advertising / data management. This scan could not identify 33 of the 54 third-party hosts recorded here, so it cannot say who operates them. That is a limit of identity coverage, not evidence about the site.

164 cross-site requests across 54 third-party hosts.Elevated distinct tracking-service entities count (at or above the 6 reference threshold).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.

17 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.

Google Analytics host observed; no stats.g.doubleclick.net request.Show catalog-matched requests

Review-worthy

Third-party cookies were present

35 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.

60 cookies total in this report.High third-party cookies count (at or above the 12 reference threshold).

Context

Input-monitoring signal involving a third-party script

Listener coverage that could observe typing-related input events was registered through call chains that included a third-party script.

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.

307 interaction-listener registrations with https://cdn.intergient.com/, https://*.google.com/ and https://metrics.rapidedge.io/, plus 4 others in the registration call chain and 9 input-listener registrations with https://cdn.intergient.com/, https://*.google.com/ and https://metrics.rapidedge.io/, plus 2 others in the registration call chain

Context

Fingerprint-like browser APIs were called

2 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.

Brave Shields Comparison

No blocking → Brave-list blocking delta

No blocking: 14,803msBrave-list blocking: 9,920ms
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.coolmathgames.com/{seg}) 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.

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 .
