Public evidence register

Known-service catalog and validation fixtures

The catalog contains maintainer-assigned mappings from domain suffixes to recognizable services. Each mapping has a reviewer, review date, and functional rationale. Its official link identifies the named entity or product; it may not list that suffix or support the maintainer's category. A match is a useful lower-bound label—not proof of why a request occurred, what it carried, or whether it complied with law.

Search the service catalog

This is the effective catalog used for report labels. It is maintained in-repository and does not import a competitor tracker dataset. Functional categories are review prompts, not privacy grades.

Reference scope: an official page identifies the named entity or product only. It is not presented as a citation for every suffix or as support for the maintainer-assigned category. The mapping and category remain reviewable project assertions; report evidence should always be checked in context.

Detector validation fixture coverage

The matrix below is generated from exact, source-controlled cases in the repository test suite: one positive, one negative, and one adversarial or failure-boundary case for every detector. 2 selected cases run in real Chromium; the others test deterministic detector logic.

This is an acceptance-fixture inventory, not a representative labeled web corpus. It does not support a precision, recall, accuracy, or “all trackers detected” claim. The limitations shown for each detector remain part of the result even when every fixture passes.

Fingerprint and behavior heuristics

fingerprint-heuristics · fingerprint-observer@1

1 positive1 negative1 adversarial/boundary1 real Chromium

These cases exercise selected APIs, attribution paths, and hostile-page behavior. A matching pattern can have a legitimate use, and uninstrumented browser surfaces remain outside coverage.

Inspect source-pinned cases

Synthetic input sentinel

keystroke-exfiltration · synthetic-sentinel@1

1 positive1 negative1 adversarial/boundary0 real Chromium

Coverage is bounded to visible fields the scan probes, captured HTTP requests, and the documented plain, encoded, and hashed sentinel forms. It does not cover arbitrary encryption or uncaptured transports.

Inspect source-pinned cases

CNAME uncloaking

cname-uncloaking · dns-cname-chain@1

1 positive1 negative1 adversarial/boundary0 real Chromium

Classification depends on the DNS chain observed during the visit and the curated service catalog. A CNAME match is a routing observation, not proof of a request's purpose.

Inspect source-pinned cases

Advertising pixel events

pixel-events · pixel-request-decoder@1

1 positive1 negative1 adversarial/boundary0 real Chromium

Decoding covers reviewed request formats for Meta, TikTok, and X. Unknown products, changed payload formats, and custom event meaning are not inferred.

Inspect source-pinned cases

Consent banner and controls

consent-banner · consent-control-and-state@1

1 positive1 negative1 adversarial/boundary1 real Chromium

Cases cover known CMP selectors and conservative first-layer labels. Finding or clicking a control does not establish legal validity or prove that every request honored the choice.

Inspect source-pinned cases

Privacy-policy cross-check

privacy-policy · policy-text-cross-check@1

1 positive1 negative1 adversarial/boundary0 real Chromium

The detector checks narrow, testable phrases in an eligible policy page. It does not interpret a complete policy, determine compliance, or infer the meaning of ambiguous legal language.
