Overview

Analysis recorded

5 finding categories to review

Opal Travel (au.com.opal.travel) scored grade A, 90 out of 100, in a static scan of version 10.6.0 on 2026-10-08. It has no high or critical findings, and 5 lower-severity finding categories across 7 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

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).

Verification
Static detection; current reachability is not established.
Open in all findingsRequest a correction
lowBackground location access with advertising SDKs present1 occurrence

Interpretation & review guidance

The app can access location in the background (even when closed) and also ships advertising/attribution SDKs. Background location is a heightened-scrutiny area for Google Play and privacy regulators; confirm it is essential and disclosed, and that location isn't shared with ad networks.

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.

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)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.

  • Precise location, Approximate location, Background location requested while 1 ad/attribution SDK(s) are present (Google AdMob) — location commonly feeds ad targeting.
  • Persistent-identifier APIs referenced in code (Advertising ID (AAID), Android ID, Device ID / IMEI) with 5 analytics/ad SDK(s) present — the mechanism used for cross-app profiling.
  • 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.
