Privacy Policy

Last updated: February 28, 2026

What we collect

When you sign in with Google or a magic link, we store your email address and a profile record so we can sync your study progress across devices.

Study data

We store which words you've marked as learned, when you learned them, and any notes you've written. This data is tied to your account so it can sync between devices. If you don't sign in, everything stays in your browser's local storage and we collect nothing.

What we don't collect

• No analytics or tracking scripts
• No advertising data
• No data sold to third parties

Third-party services

• Supabase — hosts our database and handles authentication
• Google OAuth — used if you choose to sign in with Google
• Netlify — hosts the website

Each service has its own privacy policy governing how they handle your data.

Data deletion

You can reset all your study data from within the app at any time. To delete your account entirely, email [email protected].

Changes

If this policy changes, we'll update the date at the top of this page.
