Terms of Service

Effective: August 26, 2026

1. Agreement

These terms are an agreement between you and Steelheart Labs LLC ("Steelheart," "we"). By downloading or using OuraSync (the "app"), you accept them. These terms also serve as the end-user license agreement (EULA) for the app.

2. The Service

OuraSync syncs health metrics from your Oura account into Apple Health on your device. Using the app requires: an iPhone meeting the app's minimum iOS version, an Oura ring, an Oura account, and an active Oura membership (required by Oura for API access). Data availability, accuracy, and timeliness depend on Oura's services, which we do not control.

3. Subscription

4. Not Medical Advice

OuraSync moves wellness data between services you already use. It provides no analysis, diagnosis, treatment, or medical advice. Synced values are consumer wellness estimates produced by Oura's ring and algorithms, not medical measurements. Do not use the app or its data to diagnose, treat, or make medical decisions. Consult a qualified professional for health concerns.

5. Third-Party Services

The app interoperates with Oura's API (your use of Oura is governed by Oura's own terms) and Apple Health (governed by Apple's terms). OuraSync is an independent product. It is not affiliated with, endorsed by, or sponsored by Oura Health Oy or Apple Inc.

6. Acceptable Use

The app is licensed to you for personal, non-commercial use on Apple devices you own or control. You may not reverse engineer, resell, or use the app to abuse or overload Oura's or Apple's services, or use it in violation of any applicable law or third-party terms.

7. Intellectual Property

The app, its design, and its content are owned by Steelheart Labs and protected by law. We grant you a limited, non-exclusive, non-transferable, revocable license to use the app. Your health data is yours — we claim no rights to it (and never possess it; see the Privacy Policy).

8. Disclaimers

The app is provided "as is" and "as available," without warranties of any kind, express, implied, or statutory, including merchantability, fitness for a particular purpose, accuracy, and non-infringement. We do not warrant that syncing will be uninterrupted, timely, or error-free — background operation is subject to iOS scheduling and to Oura's data availability.

The same disclaimer applies to the third-party service providers the app depends on. "Third-party service providers" means Oura (Ouraring, Inc. and Ōura Health Oy), Apple Inc., and our infrastructure, diagnostics, and subscription-management providers. On their behalf as well as our own, we disclaim all warranties of any kind, express, implied, or statutory, including the implied warranties of merchantability, fitness for a particular purpose, and non-infringement. No third-party service provider warrants the app, the accuracy or availability of any data it delivers, or that access will be uninterrupted or error-free. Nothing in these terms or in the app creates any warranty from any of them.

Some states do not allow the exclusion of implied warranties, so parts of this section may not apply to you.

9. Limitation of Liability

To the maximum extent permitted by law, neither Steelheart Labs nor any third-party service provider will be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for loss of data, loss of use, or lost profits, arising out of or relating to the app — whether the claim is based on contract, warranty, tort, strict liability, or anything else, and whether or not we or they were told such damages were possible. This applies even if a limited remedy in these terms is found to have failed its essential purpose.

Steelheart Labs' total liability for any claim relating to the app is limited to the amount you paid us for the app in the twelve months before the claim arose. Third-party service providers have no liability to you under these terms; your relationship with each of them is governed by their own terms.

Some states do not allow these limits, so parts of this section may not apply to you.

Third-party service providers are intended third-party beneficiaries of sections 8 and 9 and may enforce them.

10. Termination

You may stop using the app at any time; the in-app purge tool and sign-out remove what the app wrote and stored. We may suspend or terminate the service if you breach these terms or if third-party changes (including Oura API changes) make the service impracticable.

11. Changes

We may update these terms; the current version will always be posted here with its effective date. Continued use after changes constitutes acceptance.

12. Governing Law

These terms are governed by the laws of the State of California, without regard to conflict-of-law principles. Steelheart Labs LLC is a limited liability company formed in California. If you live outside California, this choice of law does not remove any protection you have under the mandatory consumer-protection laws of the place you live. Either of us may bring a qualifying claim in small claims court.
