Your privacy is important to us. This Privacy Policy explains how we collect, use, and protect your information when you use our Flutter Cryptocurrency App.
By using the App, you agree to the terms of this Privacy Policy. If you do not agree, please do not use the App.
1. Information We Collect
We collect both personal and non-personal information to provide and improve our services.
When you create an account or sign in, we may collect the following:
Email address (from Firebase Authentication via Google Sign-In or email/password)
Profile name (if you use Google Sign-In)
Profile photo (if provided by your Google account)
We do not collect any passwords directly — all authentication is handled securely through Firebase Authentication.
1.2 Non-Personal Information
We may collect data automatically through the App, such as:
Device information (model, operating system version)
App usage statistics (crash reports, performance data)
Network information (for debugging and analytics)
Cryptocurrency market data (via the CoinGecko API)
This information does not identify you personally and helps us improve user experience.
2. How We Use Your Information
We use the collected information for the following purposes:
To authenticate and manage user accounts securely (via Firebase)
To provide real-time cryptocurrency data using CoinGecko API
To improve app functionality, performance, and user experience
To maintain security and prevent fraud
To respond to user support requests
To comply with legal obligations, if required
The App uses the following third-party services that may collect data according to their own privacy policies:
3.1 Firebase Authentication (Google)
Used for secure user sign-in and account management.
Firebase may collect device identifiers, app usage data, and authentication-related information.
Privacy Policy: https://firebase.google.com/support/privacy
Used to fetch cryptocurrency data, such as prices, trends, and charts.
CoinGecko does not collect personal data from users but may log requests for performance and security.
Privacy Policy: https://www.coingecko.com/en/privacy
To ensure full app functionality, we request the following Android permissions:
INTERNET
Required to access the internet for APIs and authentication.
ACCESS_NETWORK_STATE
Used to check network connection before performing network requests.
READ_EXTERNAL_STORAGE (for Android 12 and below)
Allows users to select or upload images from their device (e.g., for profile pictures).
READ_MEDIA_IMAGES (for Android 13 and above)
Required to access user-selected images safely.
We never access, store, or upload any media files without your explicit consent.
We retain your data only as long as necessary:
Firebase Authentication data is retained as long as your account is active.
If you delete your account, all associated Firebase data will be permanently removed.
Non-personal data (e.g., analytics) may be stored longer for app improvement.
We use modern security practices to protect your information:
Secure authentication via Firebase
Encrypted data transmission (HTTPS)
Restricted access to user data
Regular app updates for security and stability
However, please note that no system is 100% secure. We cannot guarantee absolute protection against unauthorised access or breaches.
7. Your Rights and Choices
You can:
Access and update your account information through the app.
Delete your account at any time, which permanently removes your data from Firebase.
Revoke app permissions from your device settings.
If you have any questions or requests regarding your data, contact us at the email provided below.
Our app is not directed to children under 13 years of age, and we do not knowingly collect personal data from them. If you believe a child has provided us with personal information, please contact us immediately so we can remove it.
9. Changes to This Privacy Policy
We may update this Privacy Policy periodically. Any changes will be posted within the App with a new “Last Updated” date. Continued use of the App after changes indicates your acceptance of the updated policy.
