FlashVocab

This Privacy Policy describes how FlashVocab ("we", "us", or "our") collects, uses, and protects your information when you use our mobile application ("App"). We are committed to protecting your privacy and ensuring that your personal information remains secure. By using the App, you agree to the collection and use of information in accordance with this policy.

1. Information We Collect

FlashVocab is designed with privacy as a core principle. We collect minimal information necessary to provide and improve our services. All data processing occurs on your device, and we do not collect or store personal information on external servers.

1.1 Information You Provide

• Vocabulary Data: Words and phrases you scan, add to your vocabulary lists, and your performance data related to vocabulary review (e.g., recall success, difficulty ratings). This data is stored locally on your device.
• User Preferences: Settings you configure within the App, such as language preferences, notification settings, and study reminders.
• Feedback: Any feedback or communications you voluntarily provide to us through the App or via email.

1.2 Information Collected Automatically

• Device Information: Information about your mobile device, including device model, operating system version, and unique device identifiers. This information is used solely for technical compatibility and to provide the App's functionality.
• Usage Data: Information about how you use the App, such as features accessed, time spent in the App, and interaction patterns. This data is collected locally to personalize your learning experience and improve the App.
• Camera Usage: The App may access your device's camera to scan words using OCR technology. Images captured by the camera are processed locally on your device and are not stored or transmitted outside your device unless you explicitly save them as part of your vocabulary data.

2. How We Use Your Information

We use the information we collect solely to provide, maintain, and improve the App and to develop new features and services. Specifically, we use your information for the following purposes:

• To provide and personalize the App's features, including vocabulary scanning, spaced repetition, and personalized coaching.
• To improve the App's performance and user experience based on usage patterns.
• To respond to your feedback or support requests.
• To ensure the App's compatibility with your device and operating system.
• To detect and prevent technical issues and improve the App's stability.

3. Data Storage and Security

FlashVocab is designed to process and store all data locally on your device. We do not transmit your personal information or learning data to external servers. This ensures your information remains private and accessible even when you are offline.

We implement reasonable security measures to protect your data from unauthorized access, alteration, or destruction. However, no method of electronic storage is completely secure, and we cannot guarantee absolute security. You are responsible for maintaining the security of your device and any passcodes or authentication methods used to access the App.

4. Sharing of Information

We do not share, sell, rent, or trade your personal information with third parties for their marketing purposes. We may share information in the following limited circumstances:

• With Your Consent: We may share information if you explicitly consent to such sharing.
• Service Providers: We may engage third-party service providers to assist us in providing and improving the App. These providers are contractually obligated to protect your information and use it only for the purposes for which we engage them.
• Legal Requirements: We may disclose information if required to do so by law or in response to valid requests by public authorities (e.g., a court or government agency).

5. Children's Privacy

The App is not intended for use by children under the age of 13. We do not knowingly collect personal information from children under 13. If we become aware that we have collected personal information from a child under 13 without verification of parental consent, we will take steps to remove that information from our systems.

6. Your Rights and Choices

You have the following rights regarding your information:

• Access and Correction: You can access and edit your vocabulary data and user preferences directly within the App.
• Deletion: You can delete your vocabulary data through the App's settings. You can also uninstall the App, which will remove all locally stored data from your device.
• Opt-Out: You can disable certain features that collect information, such as camera access, through your device's settings.

7. 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 and updating the "Last Updated" date. You are advised to review this Privacy Policy periodically for any changes. Your continued use of the App after any modifications to the Privacy Policy constitutes your acceptance of the revised policy.

9. Data Retention

Since all data is stored locally on your device, we do not control how long your data is retained. You can manage your data retention by using the App's features to delete unwanted vocabulary items or by uninstalling the App, which will remove all App-related data from your device.

10. Third-Party Services

The App may contain links to third-party websites or services that are not owned or controlled by us. This Privacy Policy does not apply to such third-party services. We encourage you to review the privacy policies of any third-party services you access.

11. International Data Transfers

Since all data processing occurs locally on your device, your information is not transferred across international borders. This means your data remains within the jurisdiction of your device's location.

12. California Privacy Rights

If you are a California resident, you have certain rights under the California Consumer Privacy Act (CCPA). These rights include the right to request access to the personal information we collect about you, the right to request deletion of your personal information, and the right to opt-out of the sale of your personal information. Since we do not collect or sell personal information, these rights primarily apply to your ability to access and delete your locally stored data through the App's features.

13. European Union Privacy Rights

If you are a resident of the European Union, you have certain rights under the General Data Protection Regulation (GDPR), including the right to access your personal data, the right to rectification, the right to erasure, and the right to data portability. Since all data is stored locally on your device, you can exercise these rights directly through the App's features or by contacting us at the email address provided above.
