Music Player & MP3 - DDMusic
Hitchhike Tech · Build 2.11.1
Static checks identify review items, not a guarantee of safety.
Overview
5 finding categories to review
Music Player & MP3 - DDMusic (musicplayer.playmusic.audioplayer) scored grade B, 86 out of 100, in a static scan of version 2.11.1 on 2026-10-13. It has no high or critical findings, and 5 lower-severity finding categories across 6 occurrences. 13 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
mediumCleartext (HTTP) traffic permitted1 occurrence
Interpretation & review guidance
The manifest permits cleartext (HTTP) traffic. Data sent over plain HTTP can be read or tampered with on the network; modern apps should require HTTPS.
- Evidence
- 1 recorded occurrence in the analyzed APK. These are distinct stored findings, not a count of every source match.
- Verification
- Static detection; current reachability is not established.
mediumExported content provider without permission2 occurrences
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.
- 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.
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.
- Evidence
- 1 recorded occurrence in the analyzed APK. These are distinct stored findings, not a count of every source match.
- Verification
- Static detection; current reachability is not established.

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.

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.

Privacy signals
Capabilities and bundled software do not prove that data was collected or transmitted.
Camera Draw over other apps
Requested permission inventory (35)
Data collection & flow (privacy signal, not part of the grade)
- Approximate location, Precise location requested while 7 ad/attribution SDK(s) are present (AppLovin, Google AdMob, InMobi +4 more) — location commonly feeds ad targeting.
- Persistent-identifier APIs referenced in code (Advertising ID (AAID), Android ID, Device ID / IMEI) with 10 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.
Data Safety: declared vs observed (Play label vs our analysis)
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.

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/0e82769a-58d5-4dea-90ed-c58deceafd80/findings.sarif (also coverage.json and proof.json).
