Privacy Policy

Last updated: March 2026

What we collect

When you create an account we store your email address and a hashed password. We never store passwords in plain text.

When you take quizzes, we store your quiz progress (scores, weak items, mastery stats) so you can pick up where you left off.

Payments

Payments are processed by Stripe. We do not store your credit card number. Stripe handles all payment data under their own privacy policy. We store only your Stripe customer ID to manage your subscription.

Cookies

We use a single session cookie (ns_has_session) to keep you logged in. We do not use tracking cookies or third-party analytics.

Data sharing

We do not sell, rent, or share your personal data with third parties. Your data is used only to provide the Nihongo Speedrun service.

Data deletion

You can delete your account at any time by emailing hello@nihongospeedrun.com. We will delete all your data within 30 days.
