Privacy Policy

1. Introduction

VahaLabs (“we”, “us”, or “our”) is committed to protecting your privacy. This Privacy Policy explains what information we collect, how we use it, and your rights regarding that information when you use our Platform at vahalabs.com — including the reading platform, interactive tools, and quizzes.

2. Information We Collect

2.1 Account Information (via Google Sign-In)

We use Google OAuth for authentication. When you sign in, we receive from Google:

• Your name
• Your email address
• Your Google profile picture URL

We do not receive or store your Google password.

2.2 Usage Data

• Reading progress — which chapters you have read and how far through each chapter you are
• Simulation results — for interactive chapter exercises, we store the choice you made, whether it was the rational option, and the time taken (in seconds)
• Login timestamps — when you last signed in

We collect no payment information. All books are free.

3. How We Use Your Information

• To authenticate your account and provide access to the Platform
• To save and restore your reading progress and simulation results across devices
• To improve the Platform based on aggregated, anonymised usage data

We do not sell, rent, or share your personal information with third parties for marketing purposes.

4. Third-Party Services

We use the following third-party services to operate the Platform:

5. Cookies

5.1 Session Cookies

We use session cookies required for authentication (NextAuth.js session tokens). These are necessary for the service to function and cannot be disabled while you are signed in.

We do not use tracking cookies, advertising cookies, or third-party analytics that identify you personally.

6. Data Retention

We retain your account data for as long as your account is active. If you request account deletion, we will remove your personal data within 30 days.

7. Your Rights

You have the right to:

• Access — Request a copy of the personal data we hold about you
• Correction — Ask us to correct inaccurate data
• Deletion — Request deletion of your account and associated data
• Portability — Request your data in a portable format

To exercise any of these rights, email us at vahalabsapp@gmail.com.

8. Data Security

We implement industry-standard security measures including HTTPS encryption, secure session management, and database access controls. However, no method of transmission over the internet is 100% secure. We encourage you to use a strong, unique Google account password and enable two-factor authentication on your Google account.

9. Children's Privacy

The Platform is not intended for use by individuals under the age of 18. We do not knowingly collect personal information from minors. If you believe a minor has provided us with personal information, please contact us and we will delete it promptly.

10. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of significant changes by updating the “Last updated” date at the top of this page. Continued use of the Platform after changes constitutes acceptance of the updated policy.
