Privacy Policy
Last updated August 13, 2026
Information we collect
When you create an account we store your email address and a securely hashed version of your password — we never store your password in plain text. We also store your study activity: vocabulary progress, practice answers and scores, and study plan progress, so we can show your progress and pick up where you left off.
How we use it
Your data is used only to run the service: authenticating you, saving and displaying your progress, and grading practice exercises. We do not sell your personal data to third parties.
Cookies and advertising
We use a cookie to keep you signed in. If this site displays advertising (for example, via Google AdSense), Google and its partners may use cookies to serve ads based on your visits to this and other websites. You can opt out of personalized advertising through Google Ads Settings.
Third-party services
We use Neon (database hosting) and Vercel (application hosting) to run this site; both process data on our behalf under their own security and privacy practices. We may also use Google AdSense and/or Google Analytics to support and measure the free service.
Data retention and deletion
We keep your account and progress data for as long as your account is active. To request deletion of your account and associated data, email us at the address below.
Children's privacy
This site is not directed at children under 13, and we do not knowingly collect personal information from children under 13.
