Terms

Terms of Use

Last updated: July 2026

These terms cover use of Harper, a service from Oto Health. Clinics accept these terms — and our Business Associate Agreement, which governs how we protect patient health information under HIPAA — when they create a Harper account. Questions: support@joinoto.com.

What Harper is

Harper is everyday behavioral support that helps people settle into new hearing aids through friendly text-message check-ins. Harper is not a medical device. It does not diagnose, assess, treat, cure, or prevent any condition, and it is not a substitute for care from a qualified clinician. Anything clinical is referred to the patient's clinic or, in an emergency, to local emergency services.

Using the service

Clinics are responsible for enrolling only patients who are happy to receive text messages, and for keeping their access credentials secure. Patients can opt out of messages at any time by replying STOP.

Each seat is personal to one provider. A Harper subscription seat covers one named clinician and the patients that clinician enrolls for their own care. Accounts and seats must not be shared between clinicians, and a seat must not be used to enroll patients on behalf of other providers — each additional provider needs their own seat. Patients are told which provider set them up with Harper.

Subscriptions are also subject to fair use: Harper is designed to support a clinic's own hearing-aid patients through their adjustment period. If enrolment volume goes well beyond typical clinical practice, we may apply reasonable limits or get in touch to agree an arrangement that fits — email support@joinoto.com if you expect unusually high volume.

Text messages

When a clinic enrolls a patient, Harper sends a single opt-in text; the patient becomes subscribed only after they reply YES from their own phone, and that reply is their consent to receive SMS text messages from Harper. Text messages are not secure: SMS is not encrypted and could be read by anyone with access to the patient's phone. By replying YES, the patient agrees to receive these messages anyway. Harper then sends a handful of supportive check-ins over the first weeks, plus replies whenever the patient texts back — message frequency varies, and message and data rates may apply. Patients can reply HELP for help, or reply STOP to cancel at any time to unsubscribe. Text messaging opt-in data and consent are not shared with third parties. Carriers are not liable for any delayed or undelivered messages. See our Privacy Policy for how we handle information.

How we use service data

To understand and improve how well Harper works, we analyze service data — for example how many patients respond to check-ins, opt out, complete their adjustment period, keep their hearing aids, or rate the service. When we share or publish results (for example, with hearing-care clinics or hearing-aid manufacturers), we only ever use de-identified, aggregated statistics that cannot identify any patient: never names, phone numbers, or the content of anyone's messages. See our Privacy Policy for details.

Availability

We work to keep Harper reliable but provide it "as is", without warranty that messages will always send or arrive — carrier delivery is outside our control. Features and availability vary by region.
