Effective date: August 6, 2025

Woidis ("we", "our", or "us") operates the mobile application Crypto Data by Woidis ("the App"). This page informs you of our policies regarding the collection, use, and disclosure of personal data when you use our App and the choices you have associated with that data.

1. Information We Collect

We collect several types of information for various purposes to provide and improve our service to you:

• Device Information: Device model, OS version, and language settings (used to optimize app display).
• Firebase Cloud Messaging (FCM) Token: A unique token is generated to enable push notifications. This token is stored securely and is not linked to personally identifiable data.
• Analytics Data: We use anonymous data (such as session duration, feature usage, and crash logs) to understand app performance and improve user experience. This data is collected through services like Google Analytics for Firebase.
• Advertising Identifiers: We may use your device’s advertising ID for delivering personalized or contextual ads through Google AdMob.
• User Preferences: The app may store your coin watchlist, alert settings, and language preferences locally or remotely.

Woidis uses the collected data for various purposes:

• To provide and maintain the App
• To notify you about changes or important signals via push notifications
• To allow you to participate in interactive features if you choose to
• To provide customer support
• To monitor usage and improve performance
• To show non-intrusive ads via AdMob

3. Data Sharing and Third Parties

We do not sell or share your personal data with third parties. However, we use trusted services that may process anonymous data on our behalf:

• Firebase (Google LLC): For authentication, analytics, crash reporting, and cloud messaging.
• Google AdMob: For displaying banner and interstitial advertisements.
• Amazon Web Services (AWS): Our backend data (e.g., coin watchlist, notifications) is securely stored on AWS DynamoDB.

4. Data Security

We strive to use commercially acceptable means to protect your data. However, no method of transmission over the internet or method of electronic storage is 100% secure.

This App is not intended for use by anyone under the age of 13. We do not knowingly collect personally identifiable information from children.
