Terms of service

These terms are between you and Reva Inc., a Delaware C corporation at 1035 Pearl Street, Suite 400, Boulder, CO 80302. By creating an account or using Reva you agree to them. If you are agreeing on behalf of a company, you confirm you are authorised to do so.

We have written these in plain language on purpose. It would be strange to promise clarity and then hide behind four thousand words of our own.

Reva guides general mobility and gentle strength for people recovering at home. It is not physical therapy, medical advice, diagnosis, or treatment, and using Reva does not create a therapist-patient or doctor-patient relationship.

Sessions are produced by language models and tuned to what you tell Reva about how you feel. They can be wrong, particularly about your specific situation. You are responsible for moving within your own comfort. Stop if anything hurts, and stop immediately if anything described in the safety section applies to you.

If you are following a formal rehabilitation programme set by a clinician, keep following it. Reva is a gentle complement to that, not a replacement for it. For any medical question, contact your doctor, surgeon, or physical therapist.

If you experience chest pain, difficulty breathing, numbness or tingling, a joint giving way, new calf swelling or redness, sharp or worsening pain, dizziness, a fall, or any other symptom that worries you: stop, do not use Reva, and contact a medical professional or your local emergency number. Reva screens for these before every session, and if it sees one it will tell you to stop instead of building a session. Use the same judgement yourself.

• You need an account, and the information on it must be accurate.
• You are responsible for what happens under your account, so keep your password to yourself.
• You must be 18 or older to use Reva.
• Tell us promptly if you think someone else is using your account.

The descriptions you write and the sessions Reva produces for you are yours. You grant us only the licence needed to run the service: to process your descriptions, send them to a model provider to produce your session, and store the result for you.

We do not use your recovery descriptions to train models, we do not sell them, and we do not share them with anyone other than the model provider producing your session. You can delete any session, or your whole account, at any time from Settings.

• Use Reva in a way that is unsafe, or continue using it after being told by a clinician to rest.
• Resell or white-label Reva sessions as your own service without a written agreement with us.
• Attempt to extract the prompts or scrape the service in bulk.
• Upload malware, or deliberately try to break the service for other people.

• The free plan includes one new session per calendar day, reset at midnight UTC, with the full safety screen on every session.
• Plus is $12 a month and Care is $29 a month, in US dollars. Annual billing is ten months for twelve, charged once.
• Subscriptions renew automatically until you cancel. The cancel option is in Settings, Billing, and we will not require a phone call.
• Cancelling takes effect at the end of the period you have already paid for. You keep read access to your recovery log and drop back to the free daily session.
• If we raise prices, existing subscribers keep their price for at least 12 months and receive 30 days notice.
• Refunds: if something we did stopped Reva working for you, email us and we will refund the period.

We aim for Reva to be available and we publish incidents on the status page. We do not offer a contractual uptime guarantee at this stage of the company, and we would rather say so than promise one we have not built the redundancy to keep.

To the extent the law allows, our total liability for any claim relating to Reva is limited to the amount you paid us in the 12 months before the claim, and we are not liable for indirect or consequential loss.

Nothing here limits liability for fraud, or for anything else that cannot be limited by law. Nothing here prevents you from stopping use of Reva and seeking appropriate professional care if you are injured or unwell.

You can stop using Reva and delete your account at any time from Settings. We may suspend or close an account that breaks these terms, and where we reasonably can we will tell you why first and give you a chance to export your recovery log.

These terms are governed by the laws of the State of Delaware, and any dispute will be heard in the state or federal courts in Delaware. We have not included an arbitration clause, because we would rather not rely on one.

If we change these terms materially we will email account holders at least 30 days before the change takes effect. Continuing to use Reva after that means you accept the new version. This version is effective 1 July 2026.
