Harper is a service from Oto Health that helps hearing-aid clinics support their patients by text message. This page explains, in plain terms, how we handle information. It is a summary, not a contract — for anything specific, email hello@joinoto.com.

What we handle

When a clinic enrols a patient, we process the patient's first name, last name, and mobile number, and the text messages exchanged with Harper. Harper may keep a short, non-clinical note about a patient (for example, which hearing aids they have or that noisy rooms are hard) so the conversation stays helpful over time. Harper does not collect or store clinical or diagnostic records.

How it's used

Information is used only to provide the service — to send supportive check-ins, to let a patient's clinic see the conversation, and to flag when a person would like a human to follow up. We do not sell personal information.

Where it lives

Data is stored on Google Cloud and messages are delivered via Twilio. Conversational replies are generated using a large language model under an agreement that covers confidential handling of the data.

Text messages

Harper communicates by SMS text message. Text messaging originator opt-in data and consent will not be shared with any third parties, excluding aggregators and providers of the text message services (such as Twilio). Message frequency varies depending on the conversation and a patient's check-in schedule. Message and data rates may apply. Reply STOP at any time to unsubscribe, or HELP for help.

Your choices

A patient can stop messages at any time by replying STOP. Clinics and patients can ask us to access or delete information by contacting hello@joinoto.com.

Harper provides behavioural support and is not a medical device. It does not diagnose, treat, or provide medical advice.
