Terms of use

1. Acceptance

By creating an account or otherwise using the Thyra mobile app or the website at thyraapp.com (together, the “Service”), you agree to these Terms of Use. If you do not agree, do not use the Service.

2. Nature of the service

Thyra is a consumer-grade nutrition and habit-tracking application for people living with hypothyroidism and Hashimoto’s thyroiditis. Features include personalized meal plans, a food validator, medication-timing reminders, symptom tracking and educational content.

Thyra is not a medical device. The Service is provided on an “as is” basis for informational and habit-tracking purposes only.

3. Medical disclaimer

Thyra does not provide medical advice, diagnosis or treatment. The content, recommendations, classifications, plans and conversations generated by the Service are for educational and habit-tracking purposes only and are not a substitute for professional medical advice.

• Always consult your physician or other qualified health provider with any questions about a medical condition or before starting, changing or stopping any treatment.
• Never disregard professional medical advice or delay seeking it because of something you read or saw in Thyra.
• If you think you may have a medical emergency, call your local emergency number immediately.

4. Eligibility

You must be at least 18 years old to create an account. By using the Service you represent that you meet this requirement and that all information you provide is accurate. The Service is not intended for use during pregnancy without consultation with your physician.

5. Your account

You are responsible for maintaining the confidentiality of your account credentials and for all activity that occurs under your account. Notify us promptly at hello@thyraapp.com if you suspect unauthorized access. You may delete your account at any time from inside the app.

6. Subscriptions and billing

Some Thyra features require a paid subscription. Subscriptions are sold and processed by Apple App Store or Google Play under their respective terms. Specifically:

• Subscription fees are billed at the start of each subscription period and are non-refundable except where required by law or by App Store / Play Store policies.
• Subscriptions automatically renew at the end of each period unless you cancel at least 24 hours before renewal.
• You can manage or cancel your subscription at any time in your App Store or Google Play account settings.
• Changes to subscription pricing will be communicated in advance and will take effect at the next renewal.

7. Free trial

If we offer a free trial, you will not be charged during the trial period and the subscription will begin automatically at the end of the trial unless you cancel before it ends. Trial eligibility is per Apple ID or Google account; only one trial per user.

8. Permitted use

You agree not to:

• Resell, redistribute or commercially exploit the Service or any part of it.
• Reverse-engineer, decompile or attempt to extract the source code of the app.
• Scrape, harvest or bulk-download the blog content, recipes or food database.
• Use the Service to harass, abuse or harm another person.
• Use the Service to violate any applicable law or regulation.
• Attempt to bypass authentication, rate limits or security mechanisms.
• Submit content that is illegal, infringing, defamatory or otherwise objectionable.

9. Your content

You retain ownership of the symptom logs, food entries, photos, lab uploads and messages you submit (“Your Content”). You grant Thyra a worldwide, non-exclusive, royalty-free license to host, store, process and display Your Content solely to operate and improve the Service for you.

We do not use Your Content to train third-party AI models. Aggregated, anonymized statistics derived from usage may be used for product research.

10. Intellectual property

The Service, including its software, design, text, graphics, recipes, food classifications and educational articles, is owned by Thyra or its licensors and is protected by copyright, trademark and other laws. Except as expressly permitted, you may not copy, modify, distribute or create derivative works.

Scientific citations and external sources referenced in our content remain the property of their respective authors and publishers.

11. AI output

Some features generate output using third-party AI models. AI output may be inaccurate, incomplete or out of date. You are responsible for evaluating the suitability of AI output before acting on it. AI output is not medical advice and must not be used as a substitute for consultation with a qualified health professional.

12. Third-party services

The Service relies on third-party providers (Apple, Google, Supabase, OpenAI, RevenueCat, Amplitude, Sentry, AppsFlyer, Resend, Vercel). Their terms govern your interaction with their portions of the Service. We are not responsible for outages, errors or actions of these providers beyond our reasonable control.

13. Termination

We may suspend or terminate your account if you breach these Terms, abuse the Service, or for legal or operational reasons. You may stop using the Service and delete your account at any time. Sections that by their nature should survive termination (intellectual property, disclaimers, liability, indemnification, governing law) will survive.

14. Warranties and disclaimers

To the maximum extent permitted by law, the Service is provided “as is” and “as available,” without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy or non-infringement. We do not warrant that the Service will be uninterrupted, error-free or secure, or that AI output will be accurate.

15. Limitation of liability

To the maximum extent permitted by law, in no event will Thyra, its affiliates, officers, employees or agents be liable for any indirect, incidental, special, consequential or punitive damages, or any loss of profits, revenues, data or goodwill, arising out of or in connection with your use of the Service.

Our total aggregate liability for any claims arising out of or related to the Service will not exceed the greater of (a) the amount you paid us in the 12 months preceding the claim, or (b) USD 50.

These limitations do not exclude liability that cannot be limited by applicable law (such as gross negligence or willful misconduct).

16. Indemnification

You agree to indemnify and hold harmless Thyra and its affiliates from any claim, loss or expense (including reasonable attorneys’ fees) arising from your breach of these Terms, your misuse of the Service, your violation of any law, or your violation of any third-party rights.

17. Governing law

These Terms are governed by the laws applicable at our principal place of business, without regard to conflict-of-law principles, except where mandatory consumer-protection laws of your country of residence apply.

18. Disputes

We hope to resolve any dispute informally. Please contact us first at hello@thyraapp.com. If a dispute cannot be resolved informally, both parties agree to resolve it through the competent courts at our principal place of business, except where mandatory law gives consumers the right to use their local courts.

Nothing in these Terms limits your right as a consumer to seek redress with your local consumer-protection authority.

19. Changes to these terms

We may update these Terms from time to time. When we make material changes we will update the “last updated” date and, where appropriate, notify you in the app or by email at least 14 days before the changes take effect. Your continued use of the Service after the effective date means you accept the updated Terms.
