Dumbbell Home Workout
LifeBuddy, Workout & Fitness · Build 3.6.198
Static checks identify review items, not a guarantee of safety.
Backend checks: 3 unauthenticated read checks against backends referenced in this build — 2 refused access, 1 answered. Each check describes one request at the recorded scan time and does not establish the backend's current state.
Overview
1 high or critical finding category to review
Dumbbell Home Workout (com.tv.lifebuddy) scored grade D, 42 out of 100, in a static scan of version 3.6.198 on 2026-11-08. It has 1 high or critical finding category of 4, across 5 occurrences. One finding was confirmed live: an anonymous request reached a backend the app references and it answered without authentication. No credential was used and no stored data was read. 5 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
criticalFirebase Storage bucket reference — confirmed publicly readable1 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.

Reference: CWE-200 · CWE-284 · MASVS-STORAGE-2 — 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.
- Verification
- 1 historically verified occurrence at the recorded scan time. Current reachability is not established.
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.

Privacy signals
Capabilities and bundled software do not prove that data was collected or transmitted.
Storage
Requested permission inventory (20)
Data collection & flow (privacy signal, not part of the grade)
- Persistent-identifier APIs referenced in code (Advertising ID (AAID), Android ID, Device ID / IMEI) with 4 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.

Embed this grade
The badge reads the latest recorded grade each time it is loaded, and links back to the full report so a reader can see the build it covers and what the scan could not see.
Grades can move when a new version is scanned or when a detector is corrected. If you would rather publish a grade that cannot change under you, link a signed Proof Capsule instead.
API users can request authenticated, scan-specific exports at /v1/scans/b514cbf3-5802-4292-9efb-346b1d505ad9/findings.sarif (also coverage.json and proof.json).
