Terms of service
Last updated November 4, 2026
The service
Lucena is a chess endgame training site. The free plan includes the Basics and King and Pawn chapters and ten reps a day. Pro and Lifetime unlock every chapter, unlimited reps and the tablebase explorer.
Billing
Pro is billed monthly or yearly and renews automatically until you cancel. Lifetime is a one-time payment for the current and future chapters. Cancel any time from your account; access continues to the end of the paid period. If something is broken and we cannot fix it, email us and we will refund the current period.
Your account
Keep your sign-in email secure. You are responsible for activity under your account. One account per person.
Content
Lesson text, the curriculum structure and the site design belong to Lucena. The chess positions themselves are part of chess culture and are not claimed. You may not scrape, copy or resell the course.
No guarantees
We work hard to keep every verdict correct and the site available, but the service is provided as is. Rating gains depend on you.
