Notes
Mobile_V5 · Build 7.6.1
Rescanning re-reads this build; it does not re-check any backend referenced inside it.
Static checks identify review items, not a guarantee of safety.
Backend checks: 3 unauthenticated read checks against backends referenced in this build — 3 refused access. Each check describes one request at the recorded scan time and does not establish the backend's current state.
Overview
4 finding categories to review
Notes (com.task.notes) scored grade B, 91 out of 100, in a static scan of version 7.6.1 on 2026-11-09. It has no high or critical findings, and 4 lower-severity finding categories across 6 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
mediumShort signing key (RSA 1024-bit)1 occurrence
Interpretation & review guidance
The signing key is shorter than the modern 2048-bit RSA minimum. Short keys are cryptographically weaker; a release should re-key to at least RSA-2048 (or an EC key).

lowAlibaba Cloud OSS bucket reference2 occurrences
Interpretation & review guidance
An Alibaba Cloud OSS bucket reference. Normal to use object storage; risky only if the bucket ACL allows public read/list.

lowAmazon S3 bucket reference1 occurrence
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.

Is this your app?
This app's Play listing points to amazonaws.com, which is shared hosting, so a domain check can't tell your site from another customer's. Email security@apk-scanner.com from the developer address shown on Google Play.

lowPrivate key material (third-party library artifact, shared across 192 unrelated developers)2 occurrences
Interpretation & review guidance
A complete PEM private-key block is embedded in the app. This is a real finding worth review — but it is often a bundled library test/sample key rather than a production secret, so we flag it high and leave confirmation to you (a bare header alone no longer triggers it).

Privacy signals
Capabilities and bundled software do not prove that data was collected or transmitted.
Microphone Storage
Requested permission inventory (27)
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.
- Microphone, 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/e9ad9eef-5d5a-4716-a00a-4618f94790f3/findings.sarif (also coverage.json and proof.json).
