Terms of Service

1. About Carbol

Carbol is a carbohydrate estimation and meal logging tool designed to assist people managing Type 1 diabetes. It is operated by Stephen Killgour ("Carbol", "we", "us", "our"), an individual based in New Zealand.

By creating an account or using Carbol, you ("you", "user") agree to be bound by these Terms of Service ("Terms"). Please read them carefully.

2. Not medical advice: important disclaimer

Carbol is a carbohydrate estimation and meal logging tool. It provides estimates of the carbohydrate content of food from photos and voice descriptions, for your information only.

Carbol is not a medical device. It does not provide medical advice, and it does not recommend, calculate, or suggest insulin doses or any other treatment. Carbohydrate estimates are approximations, not instructions, and they may be inaccurate. They are not a substitute for weighing food, for professional dietary advice, or for the guidance of your healthcare team.

You should make all insulin, dietary, and treatment decisions yourself, in line with the advice of your doctor, diabetes specialist, or other qualified healthcare professional. Never disregard professional medical advice, or delay seeking it, because of something provided by Carbol.

3. Eligibility and responsible use

Carbol is intended for adults aged 18 or over who are capable of independently making their own treatment decisions, or who hold an account on behalf of a child or young person they care for.

By using Carbol you confirm that you understand its carbohydrate estimates are approximate, that you will review them yourself before relying on them, and that any dietary or treatment decision you make remains your own decision, made independently of the service.

Where Carbol is used to support a child or young person with Type 1 diabetes, the account must be held by a parent or legal guardian aged 18 or over. The account holder accepts these terms on their own behalf and on behalf of the person they support, and remains fully responsible for all use of the account. All carbohydrate estimates must be reviewed by the account holder, and all dietary and treatment decisions remain the account holder's own decisions, made independently of the service.

4. Beta software

Carbol is currently in a beta testing phase. The software is provided for testing and feedback purposes. It may contain bugs, errors, or inaccuracies. Features may change, be removed, or become unavailable without notice. We make no guarantee of uptime, accuracy, or continuity of service during this period.

By participating in the beta, you acknowledge these limitations and agree to provide feedback to help improve the product. Feedback may be sent to steve@carbol.co.nz.

5. Your account

You are responsible for maintaining the confidentiality of your login credentials and for all activity that occurs under your account. Notify us immediately at steve@carbol.co.nz if you believe your account has been compromised. We are not liable for any loss resulting from unauthorised access to your account.

You agree not to share your account with others, create accounts by automated means, or attempt to access another user's account.

6. Acceptable use

You agree not to:

• Use Carbol for any unlawful purpose or in violation of these Terms
• Attempt to reverse-engineer, decompile, or extract source code from the app
• Upload content that is harmful, fraudulent, or infringes the rights of others
• Attempt to circumvent any security or access control measures
• Use the service in a manner that places unreasonable load on our infrastructure
• Resell or sublicense access to the service

7. Trial and subscription

New accounts receive a 7-day free trial with up to 5 entries per day, no payment required. After the trial period, continued access requires a paid subscription.

Subscriptions are billed in advance on a monthly or annual basis. You may cancel at any time; your access will continue until the end of the current billing period. We do not offer refunds for partial billing periods except where required by applicable New Zealand consumer law.

During the beta testing phase, pricing, plan features, and trial terms may be adjusted. We will provide reasonable notice of material changes.

8. Your data

You retain ownership of all data you submit to Carbol, including meal photos, voice recordings, and health-related entries. You grant us a limited, non-exclusive licence to store and process this data solely for the purpose of providing the service to you.

We do not sell your data. We do not use your personal health data to train AI models, nor does Anthropic use your data to train theirs. AI analysis is performed via the Anthropic API; images and transcripts are transmitted for processing and retained for up to 30 days under Anthropic's standard API policy, after which they are deleted. Content flagged by Anthropic's trust and safety classifiers for usage policy violations may be retained by Anthropic for up to 2 years.

You can export or delete your data at any time from within the app settings. On account deletion, all personal data is permanently removed within 30 days.

9. Limitation of liability

To the maximum extent permitted by law, Carbol and its operator are not liable for any loss, injury, or adverse health outcome arising from your use of the service, including any decision you make based on a carbohydrate estimate it provides. Carbohydrate estimates are provided on an "as is" and "as available" basis, without warranty of accuracy. Because all treatment decisions are made by you independently, you are responsible for those decisions and their outcomes.

Nothing in these terms excludes or limits any liability that cannot be excluded or limited under applicable law, including under the New Zealand Consumer Guarantees Act and Fair Trading Act where they apply.

10. Indemnification

To the extent permitted by law, you agree to take responsibility for treatment and dietary decisions you make independently while using Carbol, and for any use of the service that breaches these terms.

11. Intellectual property

All software, design, branding, and content forming part of Carbol (excluding your personal data) are owned by or licensed to us. These Terms do not grant you any rights to our intellectual property other than a limited right to use the service for its intended purpose.

12. Termination

We may suspend or terminate your account at any time if we reasonably believe you have violated these Terms, or for operational reasons during the beta period. You may close your account at any time from the app settings.

On termination for any reason, your right to use the service ceases immediately. Provisions that by their nature should survive termination (including limitations of liability and indemnification) will continue to apply.

13. Changes to these terms

We may update these Terms from time to time. We will notify registered users of material changes by email. Continued use of the service after the effective date of any update constitutes acceptance of the revised Terms.

14. Governing law

These Terms are governed by and construed in accordance with the laws of New Zealand. Any dispute arising under these Terms will be subject to the exclusive jurisdiction of the New Zealand courts.
