Overview
3 finding categories to review
Sudoku Master Premium: Offline (com.ANOOGAMES.SudokuMasterPremiumOffline) scored grade A, 92 out of 100, in a static scan of version 3.8 on 2026-09-20. It has no high or critical findings, and 3 lower-severity finding categories across 3 occurrences. 16 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
mediumcom.squareup.okhttp3:okhttp 3.12.13 — CVE-2021-03411 occurrence
Interpretation & review guidance
The app bundles a third-party library whose declared version matches a public security advisory (CVE). This is flagged from the version the library itself ships and a curated advisory list — confirm exploitability in your context and update the dependency to the fixed version. It is not a proof of live exploitation.
- 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 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.

- 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.

Privacy signals
Capabilities and bundled software do not prove that data was collected or transmitted.
Requested permission inventory (16)
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 15 analytics/ad SDK(s) present — the mechanism used for cross-app profiling.
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/a0591d30-9f5c-4147-9f1b-7cafe7e18944/findings.sarif (also coverage.json and proof.json).
