This Privacy Policy describes how Naturalize ("we", "our", or "us") collects, uses, and shares information when you use our mobile application (the "App").
We use the collected information for the following purposes:
Local Storage: All your study data (notes, progress, preferences, viewed questions) is stored locally on your device using AsyncStorage. This data never leaves your device unless you choose to back it up through your device's cloud backup (iCloud for iOS, Google Drive for Android).
Offline Functionality: The app works 100% offline. All 128 questions and translations are downloaded and stored on your device. No internet connection is required after initial installation.
The free version of our app displays advertisements served by Google AdMob. AdMob may collect and use device identifiers, IP addresses, and usage information to serve relevant ads. Premium users do not see advertisements.

When you purchase the premium upgrade, the transaction is processed by Apple (iOS) or Google (Android). We do not store your payment information. The purchase is tied to your Apple ID or Google account.
We may use analytics services to understand app usage patterns. These services collect anonymized data and do not identify you personally.
We do not sell, trade, or rent your personal information to third parties. We may share information only in the following circumstances:
Our app is intended for users preparing for US citizenship naturalization. We do not knowingly collect information from children under 13. If you believe we have inadvertently collected such information, please contact us to have it removed.
We implement reasonable security measures to protect your information. However, no method of electronic storage is 100% secure. Since all data is stored locally on your device, we recommend:
Our app is designed for individuals preparing for US citizenship. If you use our app from outside the United States, please be aware that your information may be transferred to and stored in the United States.
We may update this Privacy Policy from time to time. We will notify you of any significant changes by updating the "Last Updated" date and, if required, through in-app notifications. Your continued use of the app after changes constitutes acceptance of the updated policy.
If you have questions or concerns about this Privacy Policy or our data practices, please contact us:
Naturalize is not affiliated with, endorsed by, or sponsored by the United States Citizenship and Immigration Services (USCIS) or any other US government agency. All questions are based on publicly available official USCIS materials.
By using Naturalize, you acknowledge that you have read and understood this Privacy Policy and agree to its terms.
