Privacy Policy

MockCert respects your privacy. This policy explains what data we collect, why we collect it, and the rights you have over it.

Data we collect

When you use MockCert we may collect: (1) anonymous usage analytics via Google Analytics 4 (page views, sessions, approximate region); (2) when you sign in with Google — the email address and display name from your Google account; (3) the results of practice exams you take while signed in (scores, per-domain correctness, timing).

Google sign-in

Sign-in runs through Supabase Auth with Google. MockCert never receives or stores your Google password — authentication happens at Google, and we only receive the identifier and email Google returns. You can revoke access at any time from your Google account.

Exam history

When signed in, your practice results are saved to your Supabase account and synced across devices. When not signed in (guest), we store no history — sample results only display for that session.

Usage analytics

We use Google Analytics 4 to understand how the site is used (which pages are viewed, performance, traffic sources). Data is aggregated and anonymized, not used to identify individuals. You can block it with browser anti-tracking tools and still practice normally.

Cookies

The site uses these cookies: NEXT_LOCALE (remembers your language), theme (light/dark), sb-* (Supabase session), g_state and _ga/_ga_* (Google). Analytics cookies can be disabled without affecting practice.

Third parties

Google (Analytics and sign-in) and Supabase (database, authentication) process data under their own policies. MockCert does not sell, rent, or trade your data to anyone else for commercial purposes.

Your rights

You can view, correct, or request deletion of your account data. To delete all your data, sign out and/or contact the email below. For users in the EU/Vietnam, you have rights under GDPR and Decree 13/2023/ND-CP on personal data protection.
