Overview

Analysis recorded

3 finding categories to review

Masters Pro: Scheduling App (ru.jamsoft.masters) scored grade A, 97 out of 100, in a static scan of version 3.75 on 2026-09-30. It has no high or critical findings, and 3 lower-severity finding categories across 4 occurrences. 8 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

lowBIP39 wallet seed phrase (12 words, checksum valid) (third-party library artifact, shared across 12 unrelated developers)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.
Open in all findingsRequest a correction
lowData Safety label omits Calendar2 occurrences

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.

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.

  • Persistent-identifier APIs referenced in code (Advertising ID (AAID), Android ID, Device ID / IMEI) with 6 analytics/ad SDK(s) present — the mechanism used for cross-app profiling.
  • Calendar, Camera, Contacts, 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 2 categories the app can access: Calendar, 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.
