Measure Master Pro Calculator
Calculated Industries · Build 10.20.18
Static checks identify review items, not a guarantee of safety.
Overview
6 finding categories to review
Measure Master Pro Calculator (com.calculated.laurene4020) scored grade B, 80 out of 100, in a static scan of version 10.20.18 on 2026-10-08. It has no high or critical findings, and 6 lower-severity finding categories across 6 occurrences. 7 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.
mediumcom.squareup.okhttp3:okhttp 3.14.9 — CVE-2021-03411 occurrence
Interpretation & review guidance
The app bundles a third-party library whose declared version matches a public security advisory (CVE). This is flagged from the version the library itself ships and a curated advisory list — confirm exploitability in your context and update the dependency to the fixed version. It is not a proof of live exploitation.
- 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.
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.

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.

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.

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.

Privacy signals
Capabilities and bundled software do not prove that data was collected or transmitted.
Precise location Approx. location Storage
Requested permission inventory (24)
Data collection & flow (privacy signal, not part of the grade)
- Approximate location, Precise location requested while 2 ad/attribution SDK(s) are present (Google AdMob, AppsFlyer) — location commonly feeds ad targeting.
- Persistent-identifier APIs referenced in code (Advertising ID (AAID), Android ID, Device ID / IMEI +1 more) with 5 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.

The badge reads the latest recorded grade each time it is loaded, and links back to the full report so a reader can see the build it covers and what the scan could not see.
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.
