Last Updated: April 10, 2026

1. Introduction

Thank you for using AI Reading Mastery ("we", "our", or "us"). We are committed to protecting your personal data and respecting your privacy. This Privacy Policy explains how we collect, use, and protect your information when you use our Chrome Extension and associated services.

2. Information We Collect

In order to provide and improve our services, we may collect the following types of information:

• Account Information: We use third-party authentication (OAuth via Google) to manage accounts and premium subscriptions securely. We access your email address and profile ID to identify your account.
• Usage Data: We may collect data on how you interact with the extension, such as daily feature usage (e.g., number of AI requests made) to enforce usage limits and improve user experience.
• Content Data: We process the text you highlight and submit for reading comprehension generation. This text is sent securely to our backend servers and third-party AI providers (e.g., OpenAI/Gemini) exclusively to generate questions and explanations. We do not use this text to identify you or train our models.

3. How We Use Your Information

We use the collected information for the following purposes:

• To provide, operate, and maintain our extension.
• To track usage limits and process premium subscriptions securely.
• To sync your personal settings, reading stats, and vocabulary library across devices.
• To analyze and improve the performance and functionality of our services.

4. Data Storage and Security

Your data is stored securely using industry-standard databases providers (e.g., Supabase) and backend services (e.g., Vercel). Authentication tokens and preferences are stored locally in your browser using Chrome Storage API. We take reasonable measures to protect your personal information from unauthorized access, alteration, or disclosure.

5. Sharing of Information

We do not sell your personal data to third parties. We only share information with trusted third-party service providers (like payment processors and AI API providers) strictly for the purpose of operating our service. These providers are bound by strict confidentiality agreements.

6. Your Rights

You have the right to access, modify, or delete your personal data. You can manage your account and subscription directly within the extension's settings. If you wish to delete your account entirely and purge all associated data, please contact us.

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. You are advised to review this Privacy Policy periodically for any changes.
