Overview

Analysis recorded

6 finding categories to review

Jaumo Dating App: Flirt & Date (com.jaumo) scored grade B, 84 out of 100, in a static scan of version 202607.1.2 on 2026-09-11. It has no high or critical findings, and 6 lower-severity finding categories across 7 occurrences. 20 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.

mediumcom.squareup.okhttp3:okhttp 3.12.13 — 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.
Open in all findingsRequest a correction
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).

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.

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 63 unrelated developers)1 occurrence

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).

  • Approximate location, Precise location requested while 13 ad/attribution SDK(s) are present (AppLovin, Chartboost, Google AdMob +10 more) — location commonly feeds ad targeting.
  • Persistent-identifier APIs referenced in code (Advertising ID (AAID), Android ID, Device ID / IMEI +1 more) with 15 analytics/ad SDK(s) present — the mechanism used for cross-app profiling.
  • Camera, Microphone 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.

✓ No obvious mismatch between the declaration and what we observe.

We compare the developer's Google Play Data Safety declaration with what the binary can actually do (permissions it requests, identifier APIs and third-party SDKs it ships). A mismatch is a capability signal to confirm — a requested permission is not proof of collection.
