What you are buying

Each OTO sound is a digital work, composed individually from the date of birth you provide, and delivered by email as audio files. Purchases are processed by Gumroad, which acts as the merchant of record.

Personal use

Your sound is yours to keep and listen to, privately, forever. It may not be resold, redistributed, or used commercially.

Cancellation and refunds

Because every full sound is composed individually for one person, orders cannot be refunded once composition has begun. If you wish to cancel before we begin, write to hello@otosound.com and we will cancel and refund your order in full.

A quiet note

OTO sounds are works of music, made for listening and rest. They are not medical products and make no medical claims.
