MangaMentor: How to Draw Manga
Sierra Chica Software SL · Build 2026.4.0
Static checks identify review items, not a guarantee of safety.
Overview
1 finding categories to review
MangaMentor: How to Draw Manga (com.sierrachica.mangamentor) scored grade A, 94 out of 100, in a static scan of version 2026.4.0 on 2026-10-10. It has no high or critical findings, and 1 lower-severity finding category across 1 occurrence. 3 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 4.2.2 — 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.
Build & components
29 components recorded. Certificate parsing does not validate APK signature integrity.

Privacy signals
Capabilities and bundled software do not prove that data was collected or transmitted.
Storage
Requested permission inventory (11)
Data collection & flow (privacy signal, not part of the grade)
- Persistent-identifier APIs referenced in code (Advertising ID (AAID), Device ID / IMEI) with 3 analytics/ad SDK(s) present — the mechanism used for cross-app profiling.
- 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.

Component inventory
29 components. Advisory matching covers a curated set; no match is not proof that a component is vulnerability-free.

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/ad942aff-a3e6-4e56-b162-379b65690d49/findings.sarif (also coverage.json and proof.json).
