Kuku FM: Audio Series
Kuku Technologies Limited · Build 6.1.2
Static checks identify review items, not a guarantee of safety.
Overview
6 finding categories to review
Kuku FM: Audio Series (com.vlv.aravali) scored grade B, 88 out of 100, in a static scan of version 6.1.2 on 2026-10-09. It has no high or critical findings, and 6 lower-severity finding categories across 12 occurrences. 9 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
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.
lowAmazon S3 bucket reference6 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
- 6 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.
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.
- 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.

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.

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.

Privacy signals
Capabilities and bundled software do not prove that data was collected or transmitted.
Background location Precise location Approx. location Camera Microphone Phone state
Requested permission inventory (39)
Data collection & flow (privacy signal, not part of the grade)
- Precise location, Background location, Approximate location requested while 2 ad/attribution SDK(s) are present (Google AdMob, AppsFlyer) — location commonly feeds ad targeting.
- Persistent-identifier APIs referenced in code (Advertising ID (AAID), Android ID, Device ID / IMEI) with 7 analytics/ad SDK(s) present — the mechanism used for cross-app profiling.
- Camera, Microphone, Phone, 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.

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/e54ace1f-29d2-468e-8378-5ac413c18ffc/findings.sarif (also coverage.json and proof.json).
