Last Updated: July 22, 2025

This Privacy Policy explains how Vaani Apps ("we," "us," or "our") collects, uses, and discloses information when you use the Math Sprint mobile application (the "App"). We are committed to protecting your privacy and ensuring a safe and enjoyable experience.

We do not collect any personal data that directly identifies you on our servers. All your test history is stored locally on your device.

1. Information We Collect

While we don't collect personal identifying information on our servers, we do collect certain data to improve the App and provide a better experience:

• Analytics Data: We use Google Analytics and Mixpanel to collect anonymous usage data. This includes basic usage data (App opens, session duration, button taps) and detailed interaction data (information related to your interactions with the math problems). This data is entirely anonymous and cannot be used to identify you personally. We do not map any user-specific information with our analytics data.
• Offline Tracking: When your device is offline, we store analytics events locally. Once your device reconnects to the internet, these events are synced with Mixpanel.
• Crash Reports: We use third-party crash reporting tools that collect anonymous data about app crashes and errors. This helps us identify and fix bugs to improve app stability.
• Device-Local Test History: We store a history of tests you've taken directly on your mobile device. This includes details like the date of the test, operation type, difficulty, number of questions, and your score. This data remains on your device and is not transmitted to our servers.

2. How We Use Information

The information we collect is used solely for the following purposes:

• To Improve App Performance
• To Understand User Engagement
• To Identify Popular Features
• To Track Bug Reports
• To Personalize Ads
• For Monetization

3. Data Retention

Anonymous analytics data is retained for a period of 12 months. After this period, the data is automatically deleted or aggregated in a way that further anonymizes it. Crash report data is retained only as long as necessary to resolve reported issues.

4. Sharing of Information

We value your privacy. We do not share any data that directly identifies you with third parties. We may share anonymous, aggregated, or de-identified data with:

• Analytics Providers: Google Analytics and Mixpanel.
• Crash Reporting Services: To help us diagnose and fix app issues.
• Advertising Partners: Our advertising SDKs may collect anonymous device identifiers to serve personalized ads.
• Payment Processors: When you make a purchase, your payment information is processed by third parties. We do not store your payment card details.

5. Children's Privacy

Math Sprint is designed for both children and adults. While we do not knowingly collect personal identifying information from anyone, including children, our use of anonymous analytics and personalized advertising means that parents should be aware of the following:

• Anonymous Data Collection: All data collected is anonymous.
• Personalized Ads: Our advertising partners may use anonymous data to deliver personalized ads.
• Parental Guidance: We encourage parents to supervise their children's use of the App.

If you believe that we have inadvertently collected any personal information from a child under the age of 13, please contact us immediately at appsvaani@gmail.com.

6. Your Choices and Rights

You can view your test history within the App. Please note that at this time, there is no in-app option to delete this history. This data is stored only on your device. Most mobile devices allow you to opt out of personalized ads through your device settings.

7. Security

We implement reasonable technical and organizational measures to protect the anonymous data we collect.

8. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page within the App.
