Effective date: 07/04/2026
Last updated: 08/28/2026

These Terms of Service (“Terms”) govern your use of the Iron Diary mobile application (“the app”), developed by Soleer LLC (“we”, “us”). By downloading or using Iron Diary, you agree to these Terms. If you do not agree, do not use the app.

1. License to use the app

We grant you a personal, non-exclusive, non-transferable, revocable license to use Iron Diary on devices you own or control, for your personal, non-commercial use, subject to these Terms and the App Store terms that apply to your download.

2. Not medical or health advice

Iron Diary is a fitness-tracking and journaling tool for informational purposes only. It is not a medical device and does not provide medical advice, diagnosis, or treatment. Any metrics it displays — including readiness summaries derived from heart rate variability, resting heart rate, or sleep — are informational and may be inaccurate or incomplete.

Always consult a qualified healthcare professional before beginning, changing, or continuing any exercise program, and do not disregard or delay seeking professional advice because of anything in the app. Exercise carries inherent risks; you are solely responsible for training safely and within your abilities. You use the app and undertake any physical activity at your own risk.

3. Your data and backups

Your data is stored locally on your device. You are responsible for maintaining your own backups. We are not responsible for any loss of data resulting from device loss or failure, deleting the app, software issues, or your own export/import actions. The app provides export and import tools to help you manage your own backups.

4. Acceptable use

You agree not to misuse the app, including by attempting to reverse engineer, decompile, or interfere with it except to the extent that restriction is prohibited by applicable law, or by using it in violation of any applicable law.

5. Intellectual property

The app and its original content, features, and design are owned by Soleer LLC and protected by applicable intellectual-property laws. The bundled exercise library and any third-party content (such as demonstration videos hosted by YouTube) remain the property of their respective owners and may be subject to their own licenses and terms. The workout data you create is yours.

6. Third-party services

The app may link to or display third-party content, such as exercise demonstration videos hosted on YouTube. Your use of such content is governed by the applicable third party's terms and privacy policy. We do not control and are not responsible for third-party services.

The app also uses a third-party analytics service, PostHog, to collect anonymous usage data, as described in our Privacy Policy.

7. Disclaimer of warranties

The app is provided “as is” and “as available”, without warranties of any kind, whether express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement. We do not warrant that the app will be uninterrupted, error-free, or that any data or metric it displays is accurate.

8. Limitation of liability

To the maximum extent permitted by law, Soleer LLC will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of data, profits, or goodwill, arising out of or related to your use of (or inability to use) the app — including any injury arising from physical activity — even if advised of the possibility of such damages.

9. Termination

You may stop using the app at any time by deleting it from your device. We may suspend or discontinue the app, in whole or in part, at any time.

10. Changes to these Terms

We may update these Terms from time to time. Material changes will be reflected by updating the “Last updated” date above. Your continued use of the app after changes take effect constitutes acceptance of the revised Terms.

11. Governing law

These Terms are governed by the laws of the State of Texas, United States, without regard to its conflict-of-laws rules.
