Overview

Analysis recorded

6 finding categories to review

Yahoo Weather: Forecast & Maps (com.yahoo.mobile.client.android.weather) scored grade A, 95 out of 100, in a static scan of version 3.2.4 on 2026-10-11. It has no high or critical findings, and 6 lower-severity finding categories across 10 occurrences. 10 tracking SDKs are present in the package, which describes what ships, not what runs or what it sends. This is static analysis of a single build: it does not observe the app running and does not establish that any data is exposed.

lowAmazon S3 bucket reference2 occurrences

Interpretation & review guidance

A reference to an Amazon S3 bucket. Using cloud storage is normal — the risk exists only if the bucket allows anonymous listing/read, which requires a separate authorized assessment.

Evidence
2 recorded occurrences in the analyzed APK. These are distinct stored findings, not a count of every source match.
Verification
Static detection; current reachability is not established.
Open in all findingsRequest a correction
lowBackground location access with advertising SDKs present1 occurrence

Interpretation & review guidance

The app can access location in the background (even when closed) and also ships advertising/attribution SDKs. Background location is a heightened-scrutiny area for Google Play and privacy regulators; confirm it is essential and disclosed, and that location isn't shared with ad networks.

lowFirebase Realtime Database reference1 occurrence

Interpretation & review guidance

A Firebase Realtime Database URL. Nearly every app that uses Firebase ships one. It's only an exposure if the database rules are world-readable — that's what live verification checks.

lowGoogle API key (client-shipped; restriction unverified)3 occurrences

Interpretation & review guidance

Android apps are designed to ship Google API keys in the client; Google restricts them by app signing certificate + enabled API. This is only a problem if the key is left unrestricted — presence alone is expected, not an exposure.

infoApplication data is backup-enabled1 occurrence

Interpretation & review guidance

The app allows Android backups (android:allowBackup="true"). App data can then be extracted via adb backup on many devices — a concern if the app stores tokens or personal/health/payment data locally. Common and low-severity, but worth disabling for sensitive apps.

  • Background location, Approximate location, Precise location requested while 4 ad/attribution SDK(s) are present (AppLovin, Google AdMob, AppsFlyer +1 more) — location commonly feeds ad targeting.
  • Persistent-identifier APIs referenced in code (Advertising ID (AAID), Android ID, Device ID / IMEI) with 8 analytics/ad SDK(s) present — the mechanism used for cross-app profiling.
  • Photos & files data requested with third-party analytics/ad SDKs present.

This maps what the app can access (permissions it requests, identifier APIs its code references) to the third parties bundled in it. It reflects capability and SDK presence — not proof that a specific value was transmitted.

✓ No obvious mismatch between the declaration and what we observe.

We compare the developer's Google Play Data Safety declaration with what the binary can actually do (permissions it requests, identifier APIs and third-party SDKs it ships). A mismatch is a capability signal to confirm — a requested permission is not proof of collection.
