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.

51 requests observed in one controlled visit.

Worth checking

10 of 50 requests the engine evaluated matched Brave Shields filter lists

10 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 7 request rows in this visit.Show matched requests

Context

This GPC comparison supports no comparable delta

The pair did not record the network egress region for both visits, and an unrecorded condition never counts as matching.

The raw request logs of both visits remain below for transparency, but the diff between them supports no claim about what the compared condition changed.

1 disqualifying condition named by the report's claim policy.

Context

Tracking companies the privacy policy does not appear to name

Google 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.

Policy at https://www.irs.gov/{seg}/{seg}; 0 checkable statements matched; 0 of 1 observed tracking company named in the policy.

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 5 third-party hosts recorded here, so it cannot say who operates them. That is a limit of identity coverage, not evidence about the site.

16 cross-site requests across 5 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.

7 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

Nothing observed

No third-party cookies observed

The automated visit did not observe third-party cookies.

This does not prove the site never uses cookies; it means this visit did not observe third-party cookies.

6 cookies total in this report.No third-party cookies observed.

Context

Interaction-monitoring signal involving a third-party script

Broad mouse, touch, click, visibility and keyboard listener coverage was registered during the visit 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.

16 interaction-listener registrations with https://*.digitalgov.gov/, https://static.addtoany.com/ and https://www.googletagmanager.com/ in the registration call chain

Nothing observed

No fingerprint-like API calls observed

The scan did not observe the instrumented high-entropy browser APIs.

This is an observation layer, not proof that fingerprinting is impossible.

0 API families recorded.

GPC Comparison

GPC off and GPC on: two visits, no comparable metric delta

GPC off: 6,927msGPC on: 6,628ms
No metric deltas are comparable across these two visits, so none are shown.
  • Request, cookie, and storage deltas (each visit's own evidence still renders below): The pair did not record the network egress region for both visits, and an unrecorded condition never counts as matching.
  • Catalog-matched request and entity deltas (each visit's own evidence still renders below): The pair did not record the network egress region for both visits, and an unrecorded condition never counts as matching.
  • Other detector and causal-path deltas (each visit's own evidence still renders below): The pair did not record the network egress region for both visits, and an unrecorded condition never counts as matching.
  • The Shields-number delta (each visit's own evidence still renders below): The pair did not record the network egress region for both visits, and an unrecorded condition never counts as matching.
  • 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

4 conditions affect how this evidence reads

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.irs.gov/{seg}/{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.

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 1 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.

16 third-party requests: 15 attributed to a single recorded actor, 1 not attributable.

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 .

Reports record one automated visit per condition; visits may be incomplete. On restart-safe deployments, an interrupted visit may be retried; attempts are never merged. Results describe these visits, not everything a site can do.
