Privacy Policy

1. Zero Forced Data Collection

MockTestBank is architected on a Guest-First, Data-Minimization principle. You can access calibrated GRE questions, test-day timers, digital calculators, and full-length scored mock exams without creating an account or providing any personal identifying information.

2. Information We Collect (When Opted In)

If you choose to create a registered account to sync your study streaks across devices, we collect only:

• Authentication Credentials: Your email address and hashed password (managed securely by Google Firebase Authentication).
• Study Analytics: Your answered question IDs, score history, and mistake error logs to generate your mastery diagnostics.

3. Local Storage vs. Cloud Storage

For guests, all answers and calculator entries remain strictly inside your browser's local sandbox (IndexedDB/localStorage) and are never transmitted to external servers. Registered users' study sessions are encrypted and stored in Google Cloud Firestore.

4. Third-Party Services & No Advertising

We do not sell, rent, or monetize your study data to advertising brokers. Infrastructure services include Google Cloud Platform (hosting and database) and Firebase App Check (reCAPTCHA Enterprise bot protection).

5. Self-Service Account & Data Deletion (GDPR & CCPA)

You retain full sovereignty over your information. You can permanently wipe your account, study history, and question attempts at any time directly through your User Profile with one click, or by emailing contact@mocktestbank.com.
