At Coin, we take your privacy seriously. This Privacy Policy outlines how we collect, use, and safeguard your personal information when you use our global currency conversion application.

1. Information We Collect

To provide a personalized experience and manage your financial records, we collect the following data:

• Account Information: Your full name and email address provided during registration.
• Credentials: An encrypted password (only if you register via email). We do not store passwords in plain text.
• Third-Party Authentication: If you choose to sign in with Google, we receive your name and email address from Google’s authentication services.
• Country Information: Your selected country of residence to optimize local currency settings and regional data.

2. How We Use Your Data

Your information is used solely for the following purposes:

• To manage your user profile and provide secure access to the app.
• To sync your budgets, expenses, and financial history across devices via our cloud database (Firebase).
• To verify your Premium status and ensure an ad-free experience.
• To provide customer support and improve our currency conversion algorithms.

3. Advertising and Premium Subscriptions

Ads: The free version of Coin may display third-party advertisements. These ad providers (such as Google AdMob) may use non-identifiable device data to serve relevant content.

Premium Accounts: Users who upgrade to Premium will enjoy an ad-free experience. Payments are processed securely through the Google Play Store. Coin does not store or process your credit card or billing information directly.

4. Data Security and Storage

We implement industry-standard security measures, including SSL/TLS encryption and secure cloud services (Firebase), to protect your data from unauthorized access, loss, or disclosure. Your budgets and expenses are tied to your unique User ID (UID) to ensure only you can access them.
