Privacy policy

Gold Master privacy policy.

Last Updated: 21.05.2026

1. Introduction

MANGAL TECH ("we", "our", or "us") operates the Gold Master mobile application (the "App"). This Privacy Policy explains what information the App stores, collects, uses, and shares when you use Gold Master.

2. Information We Collect

Gold Master is designed to keep your personal bullion records local where practical, but the App also uses platform and third-party services for live features.

  • Local App Data: Portfolio transactions, ledger records, vault settings, calculator inputs/results, alert settings, fired-alert state, notification-center history, theme/preferences, cached news, and mini-game progress or best score may be stored locally on your device using app storage. We do not operate a separate server for your local portfolio ledger.
  • Account Data: If you sign in, Firebase Authentication or another sign-in provider may process account information such as email address, display name, provider identifier, authentication tokens, and login status. If you skip login, those account features may not be used.
  • Notifications: If you enable notifications, the App may request notification permission, create local notifications, store recent notification history on your device, and use Firebase Cloud Messaging or device notification services to receive push messages. Device or messaging tokens may be processed by Firebase or the operating system to deliver notifications.
  • Diagnostics and Analytics: The App uses Firebase Crashlytics and Firebase Analytics where available to help us understand app stability, errors, feature usage, device/app version, and performance. These services may process technical identifiers, crash logs, device information, usage events, and diagnostics metadata.
  • Advertising and Purchases: Gold Master may use Google AdMob to show ads in non-premium experiences. AdMob and related Google services may process advertising identifiers, device information, approximate location, ad interaction data, and usage signals according to Google policies and your device settings. In-app purchases, including ad removal, are processed by the app store or billing provider. The App may store purchase status locally to restore premium behavior.
  • Market, News, and Premium Content: The App may connect to market-data APIs, news APIs, RSS feeds, and Firebase/Firestore content to show prices, charts, articles, and premium news. These providers may receive technical request information such as IP address, device metadata, app metadata, and request details.
  • Support Communications: If you contact us by email or another channel, we may receive the information you choose to provide, such as your email address, message content, screenshots, device details, or support context.

3. How We Use Information

We use information to provide app features, save your preferences, calculate portfolio and alert behavior, deliver notifications, display market/news content, show or remove ads, process purchase status, improve stability, investigate crashes, prevent misuse, respond to support requests, and comply with platform or legal requirements.

4. Third-Party Services

The App may use third-party services including:

  • Firebase Core, Authentication, Cloud Messaging, Crashlytics, Analytics, and Cloud Firestore
  • Google AdMob and Google advertising services
  • Google Play Billing or the relevant app-store billing provider
  • Market data, currency, news, RSS, and article providers
  • Device operating-system services for notifications, biometric authentication, networking, and secure platform behavior

These third parties may collect, process, store, or transfer information under their own privacy policies. We are responsible for describing how Gold Master uses them, but we do not control every technical process used by those providers.

5. Biometric Data

If you enable biometric lock features, Gold Master uses your device's native biometric authentication. We do not collect, receive, or store your fingerprint, face scan, or biometric template. Biometric verification is handled by your device operating system.

6. Permissions

Gold Master may request permissions or platform access needed for features such as internet connectivity, notifications, background refresh, restart-after-boot notification scheduling, and biometric authentication. You can control many permissions in your device settings, but disabling them may limit app features.

7. Data Storage and Retention

Local app records remain on your device until you edit them, clear them, delete your account where supported, uninstall the App, or reset device/app storage. Notification history is stored locally with a limited recent history. Third-party services may retain analytics, crash, advertising, authentication, billing, and server logs according to their own retention policies.

8. Data Sharing

We do not sell your local portfolio ledger. Information may be shared or processed when needed to operate third-party services, show ads, deliver notifications, process purchases, provide support, comply with law, enforce policies, protect rights, or maintain app safety and reliability.

9. Your Choices and Rights

You can manage app permissions in device settings, turn off notifications, clear local app data by deleting records or uninstalling the App, remove or restore purchases through the app store where available, and request account/data help by contacting us. Depending on applicable law, you may have rights to access, correct, update, erase, or withdraw consent for certain personal data.

10. Children

Gold Master is not intended for children under 13 and is not designed for users who cannot independently understand financial tracking tools. Do not use the App if you are not legally allowed to use this type of service in your location.

11. Security

We use reasonable technical and organizational measures to protect the App and its integrations. No app, device, network, or storage method is completely secure. Because many records are stored locally, you should secure your device, screen lock, backups, and account access.

12. International Processing

Third-party services used by the App may process information on servers located outside your state, region, or country. By using the App, you understand that your information may be processed where those providers operate.

13. Changes to This Policy

We may update this Privacy Policy when the App changes, when third-party services change, or when legal/platform requirements change. The updated date above shows the latest version included in the App.
