Privacy Policy for A320 Engine Operations

AeroMind (Guangzhou Shizhen Yuntu Technology Co., Ltd) publishes this educational simulator. It does not require an AeroMind account and contains no advertising, analytics, social login, registration codes, in-app purchases or subscriptions.

Simulator data

Simulator calculations, interaction history, engine logs and warning audio are processed locally. Simulator activities and engine logs are not uploaded. The app does not request contacts, photos, camera, microphone, location, advertising identifier, IMEI or device serial number.

Google Play license verification

The Android edition uses Google Play Integrity to verify a paid installation. It sends a short-lived Integrity token, package name, signing certificate digest, random request value, request timestamp, installation public key and public-key hash to the AeroMind license service. The installation private key stays in Android Keystore.

The raw Integrity token is used for the current Google verification and is not stored in the audit database. Verification records contain request and installation-key hashes, package and signature evidence, the result and time. They do not identify a Google account or payment card. Google request tokens, service-account credentials and private keys are excluded from application error logs.

The service processes the connection IP address to handle requests and limit abuse. Operational network logs may contain an IP address and request time. Verification evidence is used to resolve license failures and protect against unauthorized installations.

Offline use and Google services

A signed license is stored on the device for up to 30 days. The app attempts renewal every seven days when a network is available. Google Play processes purchase, licensing, integrity and diagnostic information under Google's privacy policy. AeroMind does not receive payment card details from Google.
