Overview

Analysis recorded

2 finding categories to review

Praktika – AI Language Tutor (ai.praktika.android) scored grade A, 98 out of 100, in a static scan of version 4.39.0 on 2026-10-13. It has no high or critical findings, and 2 lower-severity finding categories across 3 occurrences. 10 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.

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 findingsRequest a correction
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.

Evidence

  • Persistent-identifier APIs referenced in code (Advertising ID (AAID), Android ID, Device ID / IMEI) with 8 analytics/ad SDK(s) present — the mechanism used for cross-app profiling.
  • Camera, 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.
