These terms apply to your use of N-of-1 software and related project materials made available by Oisin McGrath (“the developer”, “we”, “us”). By downloading, installing, copying or using the software, you agree to these terms and to the GNU General Public License version 2 (“GPLv2”).

1. License

The software is free software licensed under GPLv2. You may redistribute and/or modify it under the terms of that license. The GPLv2 text controls over any conflict about copying and modification rights. These terms add conditions about how you use the software as an end user and limit liability to the extent permitted by law.

2. Not medical advice

N-of-1 is a personal tracking and pattern-awareness tool. It is not a medical device and does not diagnose, treat, cure or prevent any disease. Nothing in the app is clinical advice. Always seek a qualified health professional for medical decisions. If you have an emergency, contact local emergency services — do not rely on this app.

3. Your data, your responsibility

The app stores information locally under a location you choose. The developer does not host your data. You are solely responsible for:

4. Acceptable use

You must not use the software to break the law, harm others, or process personal information unlawfully. You must not misrepresent the software as providing medical care.

5. No warranty (“as is”)

To the maximum extent permitted by applicable law, the software is provided “as is” and “as available”, without warranties of any kind, whether express, implied or statutory, including merchantability, fitness for a particular purpose, and non-infringement. The entire risk as to quality, performance and outcomes is with you.

Without limiting the above, we do not warrant that the software will be uninterrupted, error-free, secure, or compatible with every device, or that it will meet your health or productivity goals.

6. Limitation of liability

To the maximum extent permitted by applicable law, the developer and contributors will not be liable for any indirect, incidental, special, consequential or punitive damages, or any loss of profits, data, goodwill or other intangible losses, arising from your use of (or inability to use) the software — whether based on warranty, contract, tort (including negligence), statute, or any other legal theory — even if advised of the possibility of such damages.

To the maximum extent permitted by applicable law, our aggregate liability for all claims relating to the software is limited to zero (AUD $0), because the software is provided free of charge. Where liability cannot be excluded but can be limited, it is limited to resupply of the software or the cost of resupply.

7. Australian Consumer Law

If you acquire the software as a consumer in Australia, you may have rights under the Australian Consumer Law (Schedule 2 to the Competition and Consumer Act 2010 (Cth)) that cannot be excluded, restricted or modified by contract.

Nothing in these terms excludes, restricts or modifies any consumer guarantee, right or remedy that cannot lawfully be excluded, restricted or modified. Where our liability for a failure to comply with a non-excludable guarantee can be limited, it is limited (at our option) to replacing or repairing the goods, or paying the cost of replacement or repair; or supplying the services again or paying the cost of having the services supplied again — as applicable to software distributed free of charge.

8. Third-party software and services

The app is built with Flutter and other third-party components that retain their own licenses. If you use optional device features or place data in third-party sync or backup tools, those providers' terms and privacy policies apply to that use. We are not responsible for third-party services.

9. Governing law

These terms are governed by the laws of Australia. You and we submit to the non-exclusive jurisdiction of the courts of Australia. Mandatory consumer protections in your place of residence may still apply.

10. Changes

We may update these terms in the project repository. Material changes will be reflected by an updated “last updated” date. If you do not agree to the updated terms, stop using the software.
