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.
fcmtoken.googleapis.com
classified as unknown · 2
Independent tracker databases attribute this domain to Google LLC (Firebase Cloud Messaging), associated with data such as device ID, app ID & version, OS — per TrackHAR (CC0).
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. 2 of 3 models answered, overall confidence high — no answer from gemini (parse). A human reviewed this domain's claims before anything here published.
Anthropic Claude — unknown
fcmtoken.googleapis.com is a Google (googleapis.com) endpoint associated with Firebase Cloud Messaging push-token registration, which is platform messaging infrastructure rather than a clear tracker, analytics, ad, CDN, or first-party host, so 'unknown' is the safest label. The app already declares collecting Device or other IDs and sharing User IDs, which plausibly covers a push registration token, so nothing here appears outside the declared label.
OpenAI — unknown
fcmtoken.googleapis.com is associated with Firebase Cloud Messaging token registration, a push-notification infrastructure function rather than a clear tracker, analytics, advertising, first-party, or CDN category. The app declares Device or other IDs and related diagnostics/performance data, so this contact does not clearly imply an undeclared data flow.
