This page aggregates measured, corroborated evidence: donors' iPhones recorded apps contacting this domain, every claim below was reported by separate accepted donations and published under a human verdict (later rows for an approved app inherit its verdict). A contact is a measurement, not an accusation — it does not show what data was sent.

What our research panel found AI-drafted · human-reviewed
We ask several independent AI models the same question and publish their answers separately — cross-vendor agreement is evidence against fabrication, and disagreement is worth seeing. 3 of 3 models answered, overall confidence medium — classification split: anthropic=unknown, openai=unknown, gemini=cdn. A human reviewed this domain's claims before anything here published.
Anthropic Claude — unknown
ocsp.digicert.com is DigiCert's OCSP responder, used for TLS certificate revocation checks rather than tracking, analytics, or advertising; none of the available categories fit this PKI/security infrastructure role cleanly, so it is best left unclassified here. Such checks are a normal byproduct of establishing secure connections and do not imply a data flow beyond the app's declared label.
OpenAI — unknown
ocsp.digicert.com is commonly used for certificate-status validation, but the provided data does not establish ownership or a tracking-related data flow. This contact does not by itself imply collection beyond the app's declared label.
Google Gemini — cdn
ocsp.digicert.com is operated by DigiCert to perform Online Certificate Status Protocol (OCSP) checks for verifying SSL/TLS certificate validity. This standard security infrastructure traffic does not constitute user tracking or data collection requiring disclosure.
