Privacy Policy

Last updated: October 26, 2026

TTP Prep is run by Test Treasure Publication ("we"). This policy explains what we collect when you use TTP Prep and how we use it. Questions: support@testtreasure.com.

What we collect

• Account details: your email address and a securely hashed password (stored by our provider, Supabase; we never see your password).
• Study progress: chapters completed, quiz answers and scores, flashcard review history and your test date, so your progress follows you across devices.
• Subscription details: your plan, its status and renewal date. Payments are handled by PayPal; we never receive or store your card or bank details.
• Technical data: standard server logs (such as IP address and browser type) kept by our hosting provider, Vercel, for security and reliability.

How we use it

Only to provide TTP Prep: to sign you in, save your progress, give you access to the plan you paid for, keep the service secure, and reply to you. We do not sell or rent your personal information, and we do not use it for advertising.

Who we share it with

Only the service providers that run TTP Prep for us: Supabase (accounts and database), Vercel (hosting) and PayPal (payments). Each processes data only to provide its service. We may disclose information if the law requires it.

How long we keep it

While your account is open. When you delete your account, your profile and study progress are deleted immediately; payment records may be kept by PayPal as the law requires.

Your choices and rights

• Delete your account and data at any time from your Account page.
• Ask us for a copy of your data or to correct it by emailing us.
• Residents of California and other US states with privacy laws have the right to know, access, correct and delete their personal information; we honor these requests for everyone.

Children

TTP Prep is not directed to children under 13, and we do not knowingly collect information from them. If you believe a child under 13 has created an account, contact us and we will delete it.

Security

Data is encrypted in transit (HTTPS) and protected by access rules so that each learner can only read their own information. No system is perfectly secure, but we work to protect your information and will notify affected users of any breach as the law requires.

Changes

We will post any changes here and update the date above.
