Privacy Policy

Last updated:

The Lotto Check & Sync System application ("we", "app", "application") respects and protects the privacy of our users. This Privacy Policy explains how we collect, use, and safeguard your information when you use our application.

1. Information We Collect

To provide you with our services, we may collect the following information:

• Account Information: When you log in, we collect your email address and basic profile information (via Google Sign-In or other providers) for authentication purposes.
• Lotto Check History: We store the history of the lottery numbers you have checked and the results, allowing you to access your personal history across devices.
• Payment Information (In-App Purchases): If you make an in-app purchase (e.g., to remove ads), the transaction is processed and stored securely by the platform provider (such as Google Play or App Store). We only store your purchase status (e.g., VIP/Ad-Free status) to provide the correct service. We never access or store your credit card details.
• Usage & Device Data: We may collect non-personally identifiable information such as device model, OS version, and general usage statistics to improve app performance.

2. Advertising

This application is provided for free and displays advertisements from third-party ad networks (e.g., Google AdMob). These ad providers may use cookies or device identifiers to serve ads relevant to your interests.

If you prefer not to see ads, you can opt for the "Remove Ads" service via our In-App Purchases.

3. How We Use Your Information

We use the collected information for the following purposes:

• To provide and maintain the application (e.g., syncing your lotto history across devices).
• To verify purchase status and grant exclusive privileges (e.g., ad removal).
• To analyze usage and improve user experience.
• To display advertisements (if you have not purchased the ad-removal package).

4. Disclosure to Third Parties

We do not sell or rent your personal information to third parties. However, we may share some data with:

• Service Providers: Such as Firebase Analytics and Google Cloud Firestore, which act as our database and authentication system.
• Ad Networks: To serve advertisements within the app.
• Legal Requirements: If required to do so by law or court order.

5. Data Security

We implement appropriate security measures to protect your information, such as storing data on highly secure cloud databases (Firebase Cloud Firestore) and using encrypted transmission (HTTPS). However, no method of transmission over the internet is 100% secure, and we cannot guarantee absolute security.

6. Data Deletion Request

You have the right to request the deletion of your personal data and usage history from our systems at any time. To request account deletion, please contact us via the provided email or use the "Delete Account" feature inside the app (if available).

7. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. Any changes will be posted on this page and are effective immediately upon posting.
