Banknote Scanner & Value Check
Anthonin Cocagne · Build 2.0.0
Static checks identify review items, not a guarantee of safety.
Overview
2 finding categories to review
Banknote Scanner & Value Check (com.weber.banknotescanner) scored grade A, 98 out of 100, in a static scan of version 2.0.0 on 2026-10-11. It has no high or critical findings, and 2 lower-severity finding categories across 3 occurrences. 6 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
lowFirebase Storage bucket reference2 occurrences
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
- 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.
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.
- 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.

Privacy signals
Capabilities and bundled software do not prove that data was collected or transmitted.
Camera Microphone Phone state
Requested permission inventory (15)
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.
- 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.

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/726c5450-68b0-47c9-ad71-4b8b0d030b2b/findings.sarif (also coverage.json and proof.json).
