Cancel: Settings → Billing → Cancel plan → confirm. Your plan keeps working to the end of the period you paid for, then your organisation moves to the free plan. Your notes stay readable and exportable.
Refund: within 14 days of a payment (the first one or any renewal), choose Request refund in Settings → Billing, or ask the support chat. The payment is refunded in full, it reaches your card in 5–10 working days, and the paid plan ends that day. Only an organisation admin can cancel or refund.
Outside the 14-day window, email support@chronixhealthgroup.com and a person will look at it.
