Overview

Analysis recorded

6 finding categories to review

Your Calendar Widget (de.mash.android.calendar) scored grade A, 90 out of 100, in a static scan of version 1.71.3 on 2026-10-11. It has no high or critical findings, and 6 lower-severity finding categories across 8 occurrences. 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

mediumCleartext (HTTP) traffic permitted1 occurrence

Interpretation & review guidance

The manifest permits cleartext (HTTP) traffic. Data sent over plain HTTP can be read or tampered with on the network; modern apps should require HTTPS.

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 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.

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.

lowPrivate key material (third-party library artifact, shared across 185 unrelated developers)2 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.

  • Calendar, Contacts, Personal info, 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.
