Overview

Limited assessment

3 finding categories to review

PID Litacka (cz.dpp.praguepublictransport) was scanned at version 4.7.0 on 2026-10-08 but is not graded, because the analysis did not complete enough of its checks for a score to mean anything. The checks that did run recorded 3 finding categories across 5 occurrences; because the analysis did not complete, the absence of anything more severe is not a result. 6 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

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.

Open in all findings Request a correction

lowFirebase Storage bucket reference2 occurrences

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: 2 recorded occurrences 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 findings Request a correction

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.
Verification: Static detection; current reachability is not established.

Approximate location, Precise 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 +3 more) with 4 analytics/ad SDK(s) present — the mechanism used for cross-app profiling.
Camera, 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.

Data Safety comparison is not conclusive because analysis coverage is incomplete or unknown.
