When you choose to sign in using Google Sign-In, our application accesses the following Google user data:

Important: We do NOT access your Google Drive files, emails, contacts, calendar, or any other Google services data. We only access the basic profile information necessary for authentication.

The Google user data we collect is used exclusively for the following purposes:

• Account Creation & Authentication: To create your user account on PhysicsExamsPrep.com and verify your identity during subsequent logins.
• Personalization: To display your name and profile picture on your account dashboard, making the experience personalized.
• Communication: To send you important updates about your account, physics exam preparation materials, and responses to your support requests (only if you opt-in or when necessary).
• Security: To detect and prevent fraudulent or unauthorized access to your account.
• Analytics: To understand user registration patterns in aggregate, non-identifiable form to improve our services.

Limited Use Disclosure: Our use of Google user data is strictly limited to providing authentication services and improving your learning experience. We do not use Google user data for advertising, marketing, or any purpose not explicitly stated in this policy.

We take your privacy seriously. Here is our policy regarding sharing Google user data:

• No Selling: We do NOT sell, rent, or trade your Google user data to any third parties.
• No Marketing: We do NOT share your data with advertisers or marketing platforms.
• Service Providers: We may share necessary data (only email and name) with trusted third-party service providers who help us operate our website (e.g., hosting provider, email service). These providers are contractually obligated to protect your data and use it only for the services they provide to us.
• Legal Compliance: We may disclose data if required by law, regulation, legal process, or enforceable government request.

While we implement industry-standard security measures, no method of transmission over the internet is 100% secure. We cannot guarantee absolute security, but we continuously work to protect your information.

We retain your Google user data only as long as necessary:
