Privacy Policy

Last updated: 8 July 2026

In short: we only keep what we need to run your chess account, we never sell your data or use ad-tracking, and you can download or delete everything at any time from your Profile.

What we keep

Your account — your username, email and a scrambled password so you can sign in.
Your chess — your games, ratings, puzzles and coaching progress, so you can pick up where you left off.
Your profile — anything you choose to add, like a country or an avatar.

Payments

Premium is billed securely through Stripe. We never see or store your card details.

AI coaching

When you use the AI coach, positions from your games are sent to our AI provider to generate advice. Your name and email are never shared.

What we never do

We don't sell your data, and we don't use advertising or third-party tracking cookies.

You're in control

Export a copy of your data or delete your account whenever you like — both are on your Profile page.
