xkcd.com's completed measurements recorded no listed activity, but some optional detector evidence was not recorded in this legacy report.
The request log recorded no cross-site hosts or catalogued tracking-related services, the cookie snapshot recorded no third-party cookie records and the fingerprint observer recorded no instrumented API events. Some optional detector evidence was not recorded in this legacy report, so whatever that check looks for is unproven here rather than shown to be absent.
The automated visit did not observe known third-party services, third-party cookies, or instrumented fingerprint-like calls.
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.
6 requests observed in one controlled visit.

When
Jul 30, 2026, 7:31 AM UTC
Setup
Headless Chromium in a desktop window of 1440 × 980, with en-US language and UTC time zone. It ran from a GitHub Actions Ubuntu runner; the network region was not recorded. It sent the Global Privacy Control (GPC) signal.
Visits
One visit.
Interactions
No typing was recorded. No scrolling, clicking or consent interaction.
Outcome
The visit completed.
What this visit could not see
Other pages on this site. Only the requested page's activity was recorded.
Signed-in visitors, other browsers and other regions. This was one automated visit from a fixed en-US / UTC profile. Sites can behave differently for real users, browsers, regions, accounts, or network locations.
Anything that loads only after interaction or consent. Trackers that load that late are not observed, so counts are a lower bound.
Services the catalog does not name. Service labels use a US-biased hand-curated catalog, so regional services may be under-labeled.
Not flagged
No requests matched Brave Shields filter lists
No requests matched the default filter lists of Brave Shields, the ad and tracker blocker built into the Brave browser.
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 0 request rows in this visit.Show matched requests
Not flagged
No known services matched
This scan did not match any third-party domains to the service catalog or another identity source.
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.
0 cookies total in this report.No third-party cookies observed.
Not flagged
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.

The findings above are built from the stored report. Load the request rows, domains, cookies, storage keys, browser signals, visit phases, charts and CSV export when you want to check them; the versioned report JSON is always available below without this interface.
This versioned report is currently retained in the public corpus. Follow the currently retained site history, repeat the same public route when it is available, or request a transparent evidence correction.
Exact build and instrument digests were not recorded by this legacy schema.
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 .
