Mastermind is developed by Colegio Solutions s.r.o. ("we", "us", or "our"). This Privacy Policy explains how our iOS application handles information.
The short version: Mastermind collects only the data you explicitly provide (your nickname and game scores) for the global leaderboard. No tracking, no ads, no analytics.
The following data is stored locally on your device:
The following data is sent to our server (colegio.cz) if you choose to participate in the global leaderboard:
Participation in the leaderboard is entirely optional. You can skip nickname setup and play without sending any data to our server.
Leaderboard data is used solely to display global rankings within the app and on colegio.cz. We do not sell, share, or use your data for any other purpose.
Leaderboard data is stored on servers operated by Active24 s.r.o. in the Czech Republic (EU). No data is transferred outside the European Union.
Mastermind offers a one-time in-app purchase ("Mastermind Pro"). All purchase transactions are handled entirely by Apple. We do not have access to your payment information, Apple ID, or any personal data related to your purchase.
The app does not integrate any third-party analytics, advertising, crash reporting, or tracking services.
Mastermind does not collect any data from anyone, including children. The app is safe for all ages.
If we ever update this policy, the new version will be posted here. As long as the app remains offline and data-free, this policy will not meaningfully change.
