Terms of Service

Last updated: August 18, 2026

These Terms are an agreement between you and Front Back Labs Inc. ("Ren," "we," "us") covering the Ren app, ren.so, and related services (the "Service"). By using the Service, you agree to these Terms and our Privacy Policy. If you do not agree, do not use the Service.

Eligibility and accounts

You must be at least 18 and legally able to enter this agreement. You are responsible for your account, the accuracy of information you provide, and keeping your credentials secure.

Wellness service only

Ren helps you conduct self-directed health and wellness experiments. It is not a healthcare provider or emergency service, and the Service—including AI output—does not provide medical advice, diagnosis, or treatment. Results may be incomplete or wrong and are not guaranteed.

Consult a qualified professional before acting on health information or changing medication, supplements, diet, exercise, or treatment. Call 911 for an emergency. You are responsible for your decisions and assume the risks of experiments you choose to conduct.

Use of the Service

You may use the Service only for lawful, personal purposes. Do not interfere with the Service, access it without authorization, introduce harmful code, reverse engineer it except where law permits, infringe another person's rights, or submit another person's health information without authority.

You retain ownership of information you submit. You give us a nonexclusive license to host, process, and display it as needed to operate and improve the Service. Ren and its licensors own the Service and its content. We give you a limited, revocable, nontransferable license to use it under these Terms. App-store terms and any applicable standard end-user license agreement also apply.

Third-party devices and services are governed by their own terms. We are not responsible for them.

Availability and termination

We may change, suspend, or discontinue the Service. You may stop using it at any time. We may suspend or terminate access for violations of these Terms, legal requirements, or risks to the Service or others.

Disclaimers and liability

To the fullest extent permitted by law, the Service is provided "as is" and "as available" without warranties. Ren is not liable for indirect, special, incidental, consequential, exemplary, or punitive damages, or lost data, profits, or health outcomes. Ren's total liability relating to the Service will not exceed the greater of $100 or the amount you paid Ren in the 12 months before the claim. These limits do not apply where prohibited by law.

General

If part of these Terms is unenforceable, the rest remains effective. We may update these Terms by posting a revised version; continued use after it takes effect means you accept it.
