Overview

Limited assessment

4 finding categories to review

Concepts: Sketch, Note, Draw (com.tophatch.concepts) was scanned at version 2026.09.3 on 2026-10-11 but is not graded, because the analysis did not complete enough of its checks for a score to mean anything. The checks that did run recorded 4 finding categories across 10 occurrences; because the analysis did not complete, the absence of anything more severe is not a result. 2 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.

lowFirebase Realtime Database reference1 occurrence

Interpretation & review guidance

A Firebase Realtime Database URL. Nearly every app that uses Firebase ships one. It's only an exposure if the database rules are world-readable — that's what live verification checks.

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
lowGoogle API key (client-shipped; restriction unverified)2 occurrences

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.

lowPrivate key material (third-party library artifact, shared across 185 unrelated developers)6 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).

infoApplication data is backup-enabled1 occurrence

Interpretation & review guidance

The app allows Android backups (android:allowBackup="true"). App data can then be extracted via adb backup on many devices — a concern if the app stores tokens or personal/health/payment data locally. Common and low-severity, but worth disabling for sensitive apps.

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

Data the app can access

All-files access
Persistent identifiers (referenced in code)

Where it can go
Third parties present (1)
Google Firebase Analytics
  • Persistent-identifier APIs referenced in code (Android ID, Device ID / IMEI) with 1 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 comparison is not conclusive because analysis coverage is incomplete or unknown.
