Overview

7 finding categories to review

5K Runner: Couch potato to 5K (com.clearskyapps.fitnessfamily.Run5K) scored grade B, 89 out of 100, in a static scan of version 8.3400 on 2026-10-22. It has no high or critical findings, and 7 lower-severity finding categories across 8 occurrences. 14 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.

Start with these findings

mediumShort signing key (RSA 1024-bit)1 occurrence

Interpretation & review guidance

The signing key is shorter than the modern 2048-bit RSA minimum. Short keys are cryptographically weaker; a release should re-key to at least RSA-2048 (or an EC key).

Reference: CWE-326 · MASVS-CRYPTO-1 — what the control asks for, and other apps with the same finding.

Evidence: 1 recorded occurrence in the analyzed APK. These are distinct stored findings, not a count of every source match.

Open in all findings Request 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.

lowData Safety label omits Location1 occurrence

Interpretation & review guidance

The app's Google Play Data Safety label omits a data category it can actually access — a permission it requests, or an advertising/device identifier it references. Under-declaring collection is a Play policy issue and a COPPA/privacy concern. This is a static signal: a requested permission is capability, not proof of collection — confirm against runtime behavior.

lowExported content provider without permission (third-party library artifact, shared across 409 unrelated developers)1 occurrence

Interpretation & review guidance

An exported content provider declares no permission. Other apps on the device may reach it — verify it enforces access control internally; this flags the attack surface, not a confirmed leak.

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)2 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.

Precise location, Approximate location, Background location requested while 2 ad/attribution SDK(s) are present (Google AdMob, Meta Audience Network) — location commonly feeds ad targeting.
Persistent-identifier APIs referenced in code (Advertising ID (AAID), Android ID, Device ID / IMEI) with 11 analytics/ad SDK(s) present — the mechanism used for cross-app profiling.
Camera, 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.

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.
