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.
firebaseinstallations.googleapis.com
classified as unknown · 2
Independent tracker databases attribute this domain to Google LLC (Firebase Installations), associated with data such as installation ID, app ID, device brand/model — 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 low — classification split: anthropic=analytics, openai=first-party · no answer from gemini (parse). A human reviewed this domain's claims before anything here published.
Anthropic Claude — analytics
firebaseinstallations.googleapis.com is a Google-operated endpoint that issues Firebase Installation IDs used by Firebase SDKs (Analytics, Crashlytics, Cloud Messaging, Remote Config), so it is best read as analytics/SDK infrastructure rather than a standalone ad tracker; note it is somewhat ambiguous since Waze is a Google-owned app, making a first-party reading also plausible. The label already declares collection of User IDs, Diagnostics and Crash logs plus sharing of Device or other IDs, which covers an installation-identifier exchange, so nothing here appears undisclosed.
OpenAI — first-party
firebaseinstallations.googleapis.com is a Google Firebase endpoint used to provision/manage app installation identifiers; Waze is a Google app. The label declares sharing of Device or other IDs, which covers this apparent identifier-related contact.
