Overview

Analysis recorded

3 finding categories to review

Quiz AI: AI Homework Helper (com.intsig.camexam) scored grade A, 92 out of 100, in a static scan of version 4.27.8.20260922 on 2026-09-30. It has no high or critical findings, and 3 lower-severity finding categories across 3 occurrences. No tracking SDKs were recognised in the package. 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).

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.
Open in all findingsRequest a correction
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.

Verification
Static detection; current reachability is not established.
Open in all findingsRequest a correction
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.

Third parties present
No analytics/advertising SDKs detected.
  • Personal-data permissions/identifiers appear on-device, but no third-party analytics/advertising SDKs were detected that would receive them.

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.
