Privacy Policy

Effective date: January 1, 2025

Welcome to ReadBubble ("we", "us", "our"). Your privacy is extremely important to us. This Privacy Policy explains what information we collect, how we use it, and how we protect it. By using ReadBubble, you agree to the practices described in this policy.

1. Information We Collect

When you create an account or use ReadBubble, we may collect the following information:

• Account information: Your name, email address, and authentication credentials (for example, Google sign-in token) used to create and secure your account.
• Learning data: Your language preferences, lesson progress, quiz scores, vocabulary lists, and other data related to your learning activity within the app.
• Usage data: General usage statistics such as session frequency, features used, and interaction patterns, collected to improve the service.
• Device information: Basic device and browser information (for example, device type, operating system, browser version) transmitted automatically when you access the service.

We do not collect sensitive personal information such as financial data, government identification numbers, or precise geolocation.

2. How We Use Your Information

We use the information we collect solely to provide, maintain, and improve ReadBubble. Specifically:

• Personalized learning: We store your progress, scores, and vocabulary so the app can remember where you left off, suggest words to review, and adapt lessons to your level.
• Account management: We use your email and credentials to authenticate you and keep your account secure.
• Service improvement: Aggregated, anonymized usage data helps us understand how the app is used and where we can improve.
• Communication: We may occasionally send you important service-related notices (for example, security alerts, major changes to the service). We will not send marketing emails without your explicit consent.

3. We Do Not Sell Your Data

We will never sell, rent, lease, or trade your personal information to any third party. Your data is yours.

4. We Do Not Share Your Data

Your learning activity, progress, scores, and personal information are never shared with other users, advertisers, or any third parties. No one else can see what you did, what lessons you completed, or what words you are learning.

5. Data Storage and Security

Your data is stored on secure servers leased from reputable cloud infrastructure providers. We implement industry-standard security measures to protect your data, including:

• Encrypted data transmission (HTTPS/TLS) for all communications between your device and our servers.
• Secure authentication mechanisms, including support for OAuth-based sign-in.
• Access controls that limit who within our team can access user data on a strict need-to-know basis.
• Regular security reviews and updates to our infrastructure.

While no system is fully secure, we take every reasonable precaution to safeguard your information.

6. Your Password and Credentials

Your password is yours and yours alone. We store passwords using secure, one-way hashing algorithms. We will never ask you for your password via email or any other channel. You are responsible for keeping your login credentials confidential.

7. Cookies and Tracking

ReadBubble may use essential cookies or local storage tokens strictly for authentication and session management. We do not use third-party tracking cookies or advertising cookies that follow you across websites.

8. Children's Privacy

ReadBubble is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. If you believe a child under 13 has provided us with personal information, please contact us and we will promptly delete it.

9. Data Retention

We retain your personal data for as long as your account is active or as needed to provide the service. If you delete your account, we will remove your personal data from our active systems within a reasonable timeframe. Some data may be retained in backups for a limited period for disaster recovery purposes.

10. Your Rights

You have the right to:

• Access the personal data we hold about you.
• Correct inaccurate or incomplete data.
• Delete your account and associated data.
• Withdraw consent for optional data processing at any time.

To exercise any of these rights, please contact us using the details below.

11. Third-Party Services

ReadBubble may integrate with third-party authentication providers (for example, Google Sign-In). These providers have their own privacy policies, and we encourage you to review them. We only receive the minimum information necessary for authentication (such as your email address and display name).

12. Changes to This Policy

We may update this Privacy Policy from time to time. If we make material changes, we will notify you through the app or by other appropriate means. Your continued use of ReadBubble after such changes constitutes acceptance of the updated policy.
