This Privacy Policy describes how Mastero — Track. Train. Master. ("we", "our", or "us") collects, uses, and shares information when you use the Mastero mobile application ("App"). By using the App, you agree to the practices described in this policy.
Information You Provide:
Information Collected Automatically:
Information from Third Parties: When you sign in with Google, Apple, or Facebook, we receive basic profile information (name, email, profile photo) as permitted by those platforms.
Your practice data is stored locally on your device using SQLite (Drift) for offline access, and in the cloud via Google Firebase (Firestore) when you are signed in and connected, enabling cross-device sync. Firebase services are operated by Google LLC and are subject to Google's Privacy Policy.
We do not sell your personal information. We share data only with: Firebase/Google (authentication, database, analytics, messaging); sign-in providers (Google, Apple, Facebook) as necessary to authenticate your identity; and as required by law.
We retain your account and practice data for as long as your account is active. If you delete your account, we will delete your data from our servers within 30 days. Locally stored data is removed when you uninstall the App.
We implement industry-standard security measures including encrypted data transmission (HTTPS/TLS), Firebase security rules to restrict data access, and secure authentication via established providers (Google, Apple, Facebook).
The App is not directed to children under 13. We do not knowingly collect personal information from children under 13. If we become aware that a child under 13 has provided us personal information, we will delete it promptly.
The App integrates Google Firebase (auth, database, analytics, messaging), Google Sign-In, Apple Sign-In, and Facebook Login. Each is governed by their own privacy policy.
We may update this Privacy Policy from time to time. We will notify you of material changes by updating the "Last Updated" date. Continued use of the App after changes constitutes acceptance.
