Terms and Conditions
Last updated 1 September 2026
Chess by Receipt is operated by Zachary Coffin.
What this is
Chess by Receipt is a service for playing correspondence chess by text message. Your opponent moves, you get a message, and you answer with your move. If you have a thermal receipt printer attached, moves print on paper as well.
The messaging programme
This is a standalone agreement to receive text messages from Chess by Receipt about your own games. It is not bundled with anything else, and agreeing to it is not a condition of any purchase.
- You opt in by texting JOIN to our number from your own phone. Only the holder of a number can sign it up.
- We do not share, sell, or provide your mobile phone number or messaging consent data to third parties or affiliates for marketing or promotional purposes. We do not buy phone numbers or consent data from anyone, and we do not take part in affiliate marketing or lead generation.
- Message frequency varies with how you play — typically a few messages per week per game.
- Message and data rates may apply.
- Reply STOP to stop all messages. Reply HELP for help.
- Carriers are not liable for delayed or undelivered messages.
Using the service
You need a mobile number that can send and receive text messages. There is no account and no password: links sent to your number are what identify you, so treat them as you would a password and do not forward them.
Do not use the service to harass anyone, to send unlawful content, or to attempt to disrupt or gain unauthorised access to it.
Your games
Moves are final once accepted, as they would be over a board. The service rejects illegal moves and tells you why; a rejected move is not played. Games with no activity for a long period may be closed.
Printers
If you attach a printer, it is yours to run and maintain. The service queues anything it cannot deliver and prints it when the machine is reachable again, but it cannot guarantee that a given slip reaches paper — text is the fallback.
Availability
This is a small service run for enjoyment. It is provided as is, without warranty of any kind. It may be unavailable, and it may lose data. Do not rely on it for anything that matters.
Ending it
You can stop at any time by replying STOP or asking us to delete your data. We may suspend access that is being used abusively.
Changes
These terms may change; the date above will change with them.
