Overview

Analysis recorded

4 finding categories to review

PayPal POS (ex Zettle) (com.izettle.android) scored grade A, 96 out of 100, in a static scan of version 8.33.0 on 2026-10-09. It has no high or critical findings, and 4 lower-severity finding categories across 4 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

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
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.

lowFirebase Storage bucket reference1 occurrence

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)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.

  • 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 5 analytics/ad SDK(s) present — the mechanism used for cross-app profiling.
  • Camera 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.
