What we store

CertTestHub stores your practice progress (mistake book, score history, daily question quota) locally in your browser (localStorage). We do not collect or transmit personal information to operate the practice tests.

What we don't collect

We do not require accounts, emails or personal data to use the free practice tests. Membership activation verifies a license key with our payment processor (Gumroad); the verification result is stored locally.

Third-party services

When ads are enabled, advertising partners may set cookies subject to your consent choices. Google Fonts may be loaded from Google's CDN.

Your choices

You can clear your practice data at any time by clearing this site's browser storage. Contact us via the contact page for any privacy questions.
