Overview

Analysis recorded

1 finding categories to review

Homework Helper - To Math AI (com.sarafan.tomath) scored grade A, 99 out of 100, in a static scan of version 1.0.b561 on 2026-10-09. It has no high or critical findings, and 1 lower-severity finding category across 1 occurrence. 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

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.

Data collection & flow (privacy signal, not part of the grade)

Data the app can access
Camera
Camera
Persistent identifiers (referenced in code)
Advertising ID (AAID)Android IDDevice ID / IMEI
Where it can go
Third parties present (4)
Google AdMobGoogle Analytics for FirebaseGoogle Firebase AnalyticsGoogle Tag Manager
  • 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 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)

Declared collected
App activityDevice or other IDsFiles and docsPersonal info
Declared shared
App activityDevice or other IDsPersonal info
We observe the app can access
no sensitive access observed
✓ No obvious mismatch between the declaration and what we observe.

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.

The certificate fingerprint identifies the parsed signing certificate. Knowing this public fingerprint does not establish ownership or validate the APK signature.

Signature integrity: not established by certificate parsing.

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/fc308827-722a-4ab2-add7-9c1f3b01adb1/findings.sarif (also coverage.json and proof.json).
