This Privacy Policy explains what information Model Defense collects and how it's used.
When you use the diagnostic, survey, or create an account, we store your survey answers (role, timeline, experience, weak areas), diagnostic scores, lesson progress, and account details (name, email, password) locally in your browser. Payment information is handled entirely by Stripe — we never see or store your card details.
Account and progress data currently live in your browser's local storage only. This means your data is not synced across devices and is not stored on our servers.
We use the information you provide to personalize your study plan, track your lesson progress, and respond to support requests submitted through our contact page or email.
Payments are processed by Stripe, subject to Stripe's own privacy policy. We do not sell or share your personal information with any other third party.
You can clear your locally stored data at any time by clearing your browser's site data for this domain. To request deletion of any information you've shared with us directly (e.g. via the contact form), email us.
Questions about this policy can be sent via our contact page.
