Calculatrice
Calculatrice is Samsung's stock popup calculator (package: com.sec.android.app.popupcalculator). 8 verified scans across 7 devices find 0 trackers - no analytics, no advertising, no attribution SDKs in the bytecode. The permission surface is minimal: 2 declared permissions, both of which warrant a brief look given that this is a calculator. For an app that adds and multiplies numbers, the footprint is about as small as it gets.
Read from the bytecode.
0 third-party SDKs means no data leaves this app through an analytics or ad library. The 2 permissions are the only surface to consider. INTERNET on a calculator is not self-evident - it could support Samsung-specific cloud or update features baked into the system image. RECEIVE_BOOT_COMPLETED lets the app register itself at device startup, which is standard for system apps that need to restore state. Neither permission proves any data leaves the device, but INTERNET is worth knowing about on an app most people assume is fully offline.
This is static analysis of the APK bytecode installed on real devices: it proves which SDK classes and manifest permissions ship in the app, not what the app transmits at runtime. Traffic analysis is a different measurement.
Hidden inside the code.
What it asks for.
Allows network access. Not an expected permission for a basic calculator - may support Samsung system-level update or cloud features.
Lets the app run code at device startup. Typical for Samsung system apps that restore UI state, but uncommon for standalone calculators.
