Start with these findings

criticalBIP39 wallet seed phrase (12 words, checksum valid)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.

Third parties present
No analytics/advertising SDKs detected.
  • Personal-data permissions/identifiers appear on-device, but no third-party analytics/advertising SDKs were detected that would receive them.

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.

Grades can move when a new version is scanned or when a detector is corrected. If you would rather publish a grade that cannot change under you, link a signed Proof Capsule instead.
