Privacy Policy

Last updated November 13, 2026

Checkmating (checkmating.io and the Checkmating apps) is run by GYM Rewards, LLC; the Android app on Google Play is published by OneCloud, LLC under this same policy. This policy explains what we collect, why, and the choices you have.

What we collect

Account: your email address, the name you show to other players, and a password (stored only as a secure hash). Optionally your country and a short "about you".
Play: your ratings, games and moves, puzzles, lessons, badges, team membership and team chat messages. Most training progress is kept on your device.
AI coach: the questions you ask and the chess position on your board, sent to our AI provider (Anthropic) to answer you. We do not use them for advertising.
Payments: handled by Apple (in the iPhone and iPad app), Google Play (in the Android app) or Stripe (on the web). We receive whether your subscription is active and when it renews, never your card details.
Technical: a session cookie to keep you signed in, and standard server logs (such as IP address) kept briefly for security.

How we use it

To run your account and games, show your name, flag and rating to other players, deliver the coach and lessons, send the emails you ask for (confirmation codes, password resets, team invites), and keep the service secure. We do not sell your data, show third-party ads, or track you across other apps and websites.

Who processes it for us

Hosting in the United States on our own servers.
Anthropic, for the AI coach.
Resend, to send email.
OpenAI and fal (ElevenLabs), to turn the app's spoken lines (lessons, the coach, bots, the commentator) into natural voices.
Stripe, Apple and Google, for payments.
Influencer Engine, on our website only (not in the apps): when you arrive from a creator's link, it counts the visit and, if you later sign up or subscribe, credits that creator. It keeps a referral ID in a cookie and in your browser's storage for up to 90 days, and sends the page address (without anything after the "?") to influencerengine.ai.

Your choices

Edit your name, country and bio in Settings.
Delete your account any time in Settings → Your profile → Delete my account, in the app or at checkmating.io. It removes your account and personal data right away; finished games keep only an anonymous id. You can also email support@checkmating.io from your account's address and we will delete it within 7 days.
Notifications are optional and can be turned off in your device settings.

Children

Checkmating is for players 13 and older. Bots' trash talk is family-friendly unless an adult turns on the 18+ setting.
