Manifest Prep is built to run without accounts. The practice exams run in your browser, and your score history is stored only on your own device (local storage) — it never leaves your device and we cannot see it.
Payment is handled by our merchant of record, Lemon Squeezy, which processes your payment details and issues your licence key under its own privacy policy; we receive only what is needed to validate licences. When you unlock the full bank, your licence key is sent to our server to be checked with Lemon Squeezy, and an anonymous device identifier is stored so your purchase works across your devices. Aggregate, anonymous analytics may be collected to improve the site. We do not sell personal data.
