Callboard
30 days, no argument. Write to sales@callboardsoftware.com within 30 days of a charge and we refund it in full. You do not have to say why.
A refund takes back the paid pairs adjudicated that came with that payment, off the key they were added to. Quote the invoice number from your receipt and we can find it.
In force from 26 October 2026.
There is nothing to open in your browser for this one, and nothing to install — so the way you try it is the free allowance, and every key is issued with 60 pairs adjudicated already on it. No card, no payment, no account.
That is the real program doing real work on our own graphics cards, not a tour of it: the only difference between the free allowance and a paid one is the number. We would rather you found out it is not for you before any money moved.
Inside 30 days of a charge: refunded in full, pairs adjudicated you have already used and all. We do not deduct them.
After 30 days: we refund the pairs adjudicated on that charge you have not used, pro rata, rounded up to the whole pair adjudicated. A monthly allowance stops renewing from the day you say so and runs to the end of the period you paid for.
A pair adjudicated that failed was never charged in the first place, so it is not a refund — it is the meter working as the terms describe. The job report names every pair adjudicated that was held back and says why.
Nothing at all to the files you have already downloaded. They are on your computer, they stay there, and no key and no payment is needed to open any of them. We could not take them back if we wanted to.
What it does to the key is what running out of pairs adjudicated does: it stops being able to start a job. If you also want the job files still sitting in that program’s folder on our machine deleted, say so in the same email and we will delete them.
One email to sales@callboardsoftware.com with the address you bought under. No form, no retention call, no offer designed to keep you. We answer within two working days and send the refund in bitcoin to an address you give us in your email.
Only where a key has been resold, used for a business it was not issued to, shared outside that business, or used to try to get work out of the program without it being counted. Nothing else on this page has conditions attached to it.
