Privacy Policy

What we collect

• Account: your name and email address.
• Learning data: your progress, reviews, streak, and settings.
• Billing: if you subscribe, Stripe holds your payment details; we only store a customer reference and your plan status.

How we use it

To run the app: sign you in, save your progress, send account emails (verification, password reset, and — only if you opt in — daily review reminders), and process subscriptions. We don’t sell your data or show ads.

Who processes your data

• Fly.io — hosting and database (EU region).
• Stripe — payment processing.
• Resend — sending account emails.
• Sentry — crash reports (with your email scrubbed).
• Umami — privacy-friendly, cookie-less page analytics (no personal profiles).

Cookies

We use essential cookies only — to keep you signed in and remember your theme preference. No advertising or cross-site tracking cookies.

Your control

You can edit your details in Settings, and delete your account (and all associated data) anytime from Settings → Danger zone. To request a copy of your data, email us.
