We built Prepvora because students deserve adaptive prep without surveillance. Here's exactly what we collect and how we protect it.
Last updated: April 2026
We collect the minimum data needed to deliver adaptive SAT practice: your email, password (hashed), practice answers, scores, and time spent per question. We do not collect government IDs, payment card details directly (Stripe handles those), or any biometric data.
Your data powers your personalized score predictions, weak-spot detection, and adaptive question routing. Aggregated, anonymized statistics may be used to improve the platform — never tied back to you.
All connections are encrypted with TLS. Passwords are hashed using bcrypt. Database access is restricted via Row-Level Security policies — even Prepvora staff cannot read your individual answers without your explicit consent.
You can export, modify, or permanently delete all your data at any time from your account settings. We honor every request within 7 days. We do not sell your data to third parties — ever.
We use a single first-party session cookie to keep you logged in. We do not use Google Analytics, Facebook Pixel, or any third-party tracking scripts on authenticated pages. Marketing pages use lightweight Vercel Analytics, which is privacy-preserving and cookie-free.
Supabase (database & auth), Vercel (hosting), Stripe (payments), and Groq (AI tutoring). Each is bound by industry-standard data processing agreements. None of them ever see your full answer history in raw form.
Active accounts: data retained as long as your account exists. Deleted accounts: all data is permanently erased within 7 days, including from backups within 30 days. Anonymized aggregate stats may persist (e.g., "average score for users practicing 30 minutes/day").
Prepvora is intended for students aged 13 and up. If you're under 13, please use our platform with parental supervision and a verified parent account.
If we materially change this policy, we will notify all active users by email at least 14 days before the change takes effect.
