Cancelling
Terms of Service (last updated 2026-10-07) s.13(b)(ii): cancel before renewal by logging in to my.functionhealth.com, Account Settings, 'Change/Cancel Membership', or by emailing hello@functionhealth.com; cancellation generally takes effect at the end of the billing cycle and access continues until then. s.13(e)(ii): full refund if cancelled within 48 hours of the initial purchase and no specimen has been collected; after that the subscription and all renewals are nonrefundable, with no prorated refund for unused tests. Unused included tests expire at the end of each subscription period (s.13(b)(iii)). FAQ: no pauses; 'Function does not offer refunds for prior payments.'
