Privacy Policy
Effective September 5, 2026
What we collect
- Account data: email, display name, password hash (we never store plaintext passwords). If you sign in with Google we store your Google account ID and avatar URL.
- Study data: every answer you submit, timing, confidence ratings, flags, notes, vocabulary reviews, essays you submit for evaluation, and conversations with the AI mentor.
- Goals: target score, test date, weekly study hours, baseline scores you enter or import.
- Billing: your Stripe customer ID and subscription status. Card numbers are handled by Stripe and never touch our servers.
- Technical: IP address (used for rate limiting), browser type, and server logs kept for a short period.
How we use it
To run the product: adapt what you practice, predict your score, generate your study plan, and answer your questions. Mentor conversations and essays are sent to our AI provider (Anthropic) to generate responses. We do not sell your data and we do not use your data to train models.
Leaderboards
You appear on leaderboards only if you opt in from Settings, and you can choose to appear anonymously.
Where it lives
Data is stored on Cloudflare infrastructure (D1, KV, R2) and processed at the edge location nearest you. Payments are processed by Stripe. Transactional email is sent via Resend.
Your controls
- Export your progress from Settings.
- Delete your account from Settings → Danger Zone. This permanently removes your account and study data.
- Email support@lsatcrusher.io for any other request.
Cookies and storage
We use browser localStorage for your session token and preferences. We do not use third-party advertising cookies.
