Static checks identify review items, not a guarantee of safety.

Backend checks: 2 unauthenticated read checks against backends referenced in this build — 1 refused access, 1 could not be determined. Each check describes one request at the recorded scan time and does not establish the backend's current state. An undetermined result is not evidence that the backend is closed.

Overview

Analysis recorded

3 finding categories to review

PenguPace: Rewards for Steps (com.pengupace) scored grade A, 97 out of 100, in a static scan of version 0.26.0 on 2026-11-07. It has no high or critical findings, and 3 lower-severity finding categories across 3 occurrences. 25 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.

lowFirebase Storage bucket reference1 occurrence

Interpretation & review guidance

A Firebase Cloud Storage bucket reference (the default <project>.appspot.com). Storing user files here is normal — it's only an exposure if the Storage security rules allow public read/list, which live verification tests.

lowGoogle API key (client-shipped; restriction unverified)1 occurrence

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.

lowSentry DSN1 occurrence

Interpretation & review guidance

A Sentry DSN. These are client-side by design (embedded in apps to send crash reports), so presence is expected; it only lets someone send events to the project, not read data. Low severity — included for inventory.

  • Persistent-identifier APIs referenced in code (Advertising ID (AAID), Android ID, Device ID / IMEI +2 more) with 20 analytics/ad SDK(s) present — the mechanism used for cross-app profiling.
  • Camera, Microphone, 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.

Data Safety: declared vs observed (Play label vs our analysis)

✓ 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.
