Most apps are not written from scratch — they embed third-party SDKs for analytics, ads, crash reporting and attribution. One SDK ships inside thousands of apps, so what a single SDK collects multiplies across everything it's embedded in. When our App Privacy Database shows an app contacting app-measurement.com or graph.facebook.com, this is usually the code doing it.
The tables below are what each SDK's own official documentation declares it collects, for Apple's Privacy Nutrition Labels (24 SDKs) and Google's Data Safety section (39 SDKs). Compiled by Privado (MIT), snapshot retrieved 2026-07-29 — SDKs change; treat this as the vendors' declared baseline, and see the measured evidence on our app pages for what actually happens on the wire.
