Privacy Policy for Magic Calculator

Effective Date: March 9, 2026

Shenzhen Waiwai Niu Education Technology Co., Ltd. ("we", "us", or "our") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, store, and protect information when you use our Magic Calculator mobile application (the "App"). By using the App, you consent to the practices described in this policy.

1. Information We Collect

Magic Calculator is designed to minimize data collection. We do not collect any personal identifiable information (PII) such as your name, email address, phone number, or location. The only data processed by the App is temporary calculation data, which is stored locally on your device and never transmitted to our servers.

2. How We Use Information

Since we do not collect personal data, we do not use, share, or sell any user information. The temporary calculation data stored on your device is used solely to provide the core calculator functionality and is deleted when you close the App or clear your device storage.

3. Data Security

We take reasonable measures to protect the local data on your device. However, since no data is transmitted to our servers, the security of local data primarily depends on your device's security settings. We are not responsible for unauthorized access to your device.

4. Third-Party Services

Magic Calculator may integrate with third-party services (e.g., Google Play Services) to provide core functionality. These third parties have their own privacy policies, and we are not responsible for their data practices.

5. Children's Privacy

Magic Calculator is not intended for children under the age of 13. We do not knowingly collect any personal information from children under 13. If we become aware of such data collection, we will take immediate steps to delete it.

6. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted in the App or on this page, and the effective date will be updated accordingly. We encourage you to review this policy periodically.
