Overview

Review needed

1 high or critical finding category to review

Lingoes Dictionary (com.luc.dict.lingoes) was scanned at version 2.4.4 on 2026-09-02 but is not graded, because the analysis did not complete enough of its checks for a score to mean anything. It has 1 high or critical finding among 4 finding categories across 5 occurrences. One finding was confirmed live: an anonymous request reached a backend the app references and it answered without authentication. No credential was used and no stored data was read. 5 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

criticalFirebase Realtime Database reference — confirmed publicly readable1 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.

Evidence
1 recorded occurrence in the analyzed APK. These are distinct stored findings, not a count of every source match.
Verification
1 historically verified occurrence at the recorded scan time. Current reachability is not established.
lowApplication 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.

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.
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.

Evidence
1 recorded occurrence in the analyzed APK. These are distinct stored findings, not a count of every source match.

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.

Evidence
2 recorded occurrences in the analyzed APK. These are distinct stored findings, not a count of every source match.
Verification
Static detection; current reachability is not established.

  • 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.

Data Safety comparison is not conclusive because analysis coverage is incomplete or unknown.
