Refund policy
Last updated 28 August 2026.
This policy covers paid API plans sold by HumanDesign.AI LTD, including when those plans are used through Human Design MCP. It sits alongside our terms of service and does not reduce any right you have under UK consumer law.
Free plan
The Free API plan carries no charge and includes 100 calls per month. There is nothing to refund and nothing to cancel.
Paid plans
Paid plans are billed in advance for the period shown at checkout and renew automatically until cancelled. The price you see at checkout is the price charged, and we will tell you before any change takes effect.
Cancelling
Cancel at any time from your account at my.humandesign.ai. Cancellation stops the next renewal. Your plan and its allowance stay active until the end of the period you have already paid for, so nothing stops working the moment you cancel.
We do not ordinarily refund the remainder of a period once it has begun, because the allowance has been made available to you for that period whether or not you used it.
Your cancellation rights as a consumer
If you are buying as an individual rather than for a business, the Consumer Contracts Regulations 2013 give you 14 days from purchase to change your mind.
Access begins immediately, and at checkout you agree to it beginning immediately. Once the service has started you may still cancel within those 14 days, and we will refund what you paid less a proportionate amount for the period already supplied. If you have made substantial use of the allowance in that time, that will be reflected in the deduction.
Business customers, including sole traders buying for their trade, do not have this statutory right, though the rest of this policy still applies.
If something is wrong with the service
Under the Consumer Rights Act 2015, digital services must be provided with reasonable care and skill and match how they were described. If the service is not working as described, tell us and we will try to put it right. Where we cannot, you are entitled to an appropriate reduction, which may be a full refund of the affected period depending on what went wrong and for how long.
A single failed call, or brief unavailability, is not ordinarily a fault of this kind. We do not offer an uptime guarantee, and integrations should handle errors gracefully.
Billing errors
If you think you have been charged in error, a duplicate has been taken, or a charge appears after you cancelled, write to support@humandesign.ai with the date and amount. We would much rather find and fix it than have you go to your bank, and we will refund a genuine error in full without argument.
Unused allowance
Monthly allowances do not roll over and are not refundable as credit. If your usage is consistently well below your plan, move down a tier rather than carrying the difference.
Suspended or terminated accounts
If we suspend or terminate access for a breach of the terms, we do not refund the current period. If we end your access for any other reason, we refund the unused remainder.
How to ask
Write to support@humandesign.ai with your account email and the charge in question. We answer in writing. Approved refunds go back to the original payment method, normally within five to ten working days depending on your bank.
