Privacy Policy

Your privacy is important to us. This policy explains how we handle your data.

Introduction

This Privacy Policy describes how Natural English Apps (the "App", "we", "us", or "our") collects, uses, and discloses your information when you use our mobile application. By using the App, you agree to the collection and use of information in accordance with this policy.

Information Collection and Use

Personal Data

We do not collect any personally identifiable information from our users. You can use the app without providing your name, email, or any other personal details.

Usage Data

We may collect data about how you access and use the App ("Usage Data"). This Usage Data may include information such as your device's Internet Protocol address (e.g., IP address), device type, operating system, unique device identifiers, language settings, and diagnostic data. This data is collected to improve the functionality and performance of the App. It is anonymized and aggregated, and cannot be used to identify you personally.

  • **Learning Progress:** Time spent learning, daily goal completion, XP (experience points), and user level. This data helps us track your progress and provide personalized learning recommendations.
  • **Quiz Performance:** Scores, correct/incorrect answers, and words identified as difficult. This data is used to adapt quizzes to your learning level and suggest appropriate vocabulary.
  • **Article Interaction:** Articles read, words looked up, and words marked as favorites. This helps tailor content and vocabulary recommendations.
  • **Voice Preferences:** Your selected voice accents and types. This preference is stored to provide a consistent listening experience.

Data Synchronization

Your learning progress, daily goals, and saved vocabulary (favorites) are synced across your iOS devices if you are signed in with the same Apple ID. This synchronization requires an internet connection and is solely for your convenience to ensure a seamless learning experience across devices. We do not store this synced data on our own servers in a personally identifiable manner; it is managed by Apple's iCloud service or similar secure cloud storage associated with your Apple ID.

Third-Party Services

The App may use third-party services that collect information for analytical purposes. These third-party service providers have their own privacy policies addressing how they use such information. We use these services to understand app usage trends and improve the app.

  • **Analytics Providers:** We may use tools like Firebase Analytics or similar services to gather anonymized usage data. These tools help us understand user behavior and improve the app.
  • **Text-to-Speech (TTS) Systems:** Our app uses advanced AI text-to-speech systems for audio playback. When you use audio features, the text is sent to these services to generate speech. These services typically have their own privacy policies regarding the processing of text for speech generation.

Data Retention

We retain Usage Data for a limited period to analyze app performance and trends. Since no personal data is collected, this Usage Data cannot be linked back to an individual. Your learning progress and favorite words are retained within the app and synced via your Apple ID until you choose to delete the app or your associated cloud data.

Data Security

The security of your data is important to us. While we do not collect personal data, we strive to use commercially acceptable means to protect the Usage Data collected from unauthorized access, use, or disclosure. However, no method of transmission over the Internet or method of electronic storage is 100% secure.

Children's Privacy

Our App is not intended for use by children under the age of 13. We do not knowingly collect personally identifiable information from children under 13. If you are a parent or guardian and you are aware that your child has provided us with personal data, please contact us. If we become aware that we have collected personal data from a child under 13 without verification of parental consent, we take steps to remove that information from our servers.

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. You are advised to review this Privacy Policy periodically for any changes. Changes to this Privacy Policy are effective when they are posted on this page.
