Static checks identify review items, not a guarantee of safety.

Overview

Review needed

1 high or critical finding category to review

Opera Mini: Fast Web Browser (com.opera.mini.native) scored grade D, 40 out of 100, in a static scan of version 99.6.2254.2363 on 2026-10-10. It has 1 high or critical finding among 6 finding categories across 12 occurrences. 18 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

criticalBIP39 wallet seed phrase (12 words, checksum valid)1 occurrence

Interpretation & review guidance

A BIP39 mnemonic seed phrase with a valid checksum is embedded in the app. This is the master key to a cryptocurrency wallet — anyone with it controls the funds. Extremely high risk; if it is a real wallet, move the funds and generate a new seed immediately.

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.
lowData Safety label omits Contacts1 occurrence

Interpretation & review guidance

The app's Google Play Data Safety label omits a data category it can actually access — a permission it requests, or an advertising/device identifier it references. Under-declaring collection is a Play policy issue and a COPPA/privacy concern. This is a static signal: a requested permission is capability, not proof of collection — confirm against runtime behavior.

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.

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)4 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)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).

  • Approximate location, Precise location requested while 10 ad/attribution SDK(s) are present (AppLovin, Chartboost, Google AdMob +7 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, Contacts, Microphone, Phone, 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.

⚠ Possible Data Safety mismatch. Label omits 1 category the app can access: Contacts.

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.
