For help with Chest, email support@chestapp.io. Include your macOS version, Chest version, and a short description of what happened. A screenshot can help; please remove personal details first.
Your chess workspace
Chest is a macOS desktop app. Play and local engine analysis work without an account. Open a PGN to study a game, use tabs to keep different games open, and explore Settings to choose your board and chessmen.
Creating an account
In Chest, open Settings → Account, choose Create account, and enter your email and a password. Open the confirmation email on the same Mac and return to Chest to finish signing in. Social sign-in buttons become available as those providers are enabled.
If an email does not arrive
Check your spam folder and the address you entered. Use the confirmation resend option in Account settings, or request a new password-reset email. Wait before requesting another email; delivery and account rate limits may apply.
If a sign-in link does not open Chest
Use the installed desktop app on the Mac where you started the request. You can also copy the full link and use the paste-link option in Account settings. Confirmation and password-reset links expire and work once; request a fresh one if needed.
Password resets and signing out
Choose Forgot password in Account settings to request a reset link. Open it on the same Mac, then choose your new password in Chest. Signing out clears the account session on that Mac and keeps your local games and settings.
Account or privacy requests
Email support@chestapp.io for account deletion or other privacy requests. We will need to verify that the account belongs to you. Never send your password, API keys, or confirmation/reset links to support.
