Terms of Service

Last updated: July 11, 2026

1. Acceptance

These Terms of Service ("Terms") govern your access to and use of myoxin and related websites, mobile apps, coach features, integrations, and messaging channels (together, the "Services"). By using the Services, you agree to these Terms and to the Privacy Policy.

If you do not agree, do not use the Services. If you use the Services on behalf of an organization, you represent that you are authorized to bind that organization.

2. Eligibility And Accounts

  • You must be legally capable of entering into these Terms in your jurisdiction.
  • You are responsible for maintaining the confidentiality of your account, linked channels, and device access.
  • You are responsible for all activity under your account unless caused by our breach.
  • You must provide accurate information and keep it reasonably current.
  • We may support anonymous, guest, or linked accounts. Those accounts are still subject to these Terms.

3. The Services

myoxin provides training, logging, analytics, coaching, reminders, subscriptions, and integration features. Features may change over time. We may add, remove, limit, suspend, or discontinue any feature at any time, with or without notice, to the fullest extent permitted by law.

We do not promise that any feature will remain available, that any beta or early-stage feature will launch fully, or that any specific result, recommendation, schedule, coach response, or integration outcome will be available on demand.

4. Not Medical Advice; Use At Your Own Risk

The Services are for informational, educational, and general fitness purposes only. They are not medical advice, diagnosis, treatment, rehabilitation, emergency services, or professional supervision.

  • Always use independent judgment and, where appropriate, consult a qualified physician or other licensed professional before beginning, changing, or continuing any program.
  • Do not rely on myoxin for emergencies, urgent symptoms, or situations where delay could cause harm.
  • If coach output, analytics, or health-related suggestions conflict with medical advice or your physical condition, follow the safer course and seek qualified help.

5. Exercise And Health Risk Assumption

Physical training, exercise, nutrition changes, and recovery decisions involve risk, including injury, illness, overtraining, falls, cardiovascular events, and other serious harm. You knowingly assume all risks arising from your training decisions and use of the Services, except to the extent such risk cannot lawfully be shifted under applicable law.

6. AI And Automated Features

The Services may use automated systems, AI models, analytics engines, and third-party providers to generate coach responses, summaries, transcripts, media descriptions, and recommendations.

  • AI output may be incomplete, incorrect, biased, unavailable, delayed, or not suitable for your circumstances.
  • You remain responsible for reviewing, validating, and deciding whether to follow any output.
  • We may log prompts, responses, tool actions, summaries, and system metadata to operate, secure, and improve the Services, subject to the Privacy Policy.

Your Google AI key (bring your own key). If you connect a personal Google AI (Gemini) API key, you authorize myoxin to use that key solely to make Google AI requests needed to provide the coach features you request. Your use of the key and Google's services is also governed by your agreement with Google. You are responsible for keeping your Google account and key secure, choosing an appropriate Google usage tier, monitoring quota and billing, applying available key restrictions and billing alerts, and promptly revoking or replacing a key you believe may be compromised.

You use a connected key at your own risk. We use reasonable technical and organizational safeguards intended to prevent disclosure or misuse, including encrypted transport, encrypted storage, access controls, owner-bound authenticated encryption, no client read-back, and a prohibition on logging raw key material. However, no system can guarantee that a key will never be exposed. To the fullest extent permitted by law, myoxin is not responsible for unauthorized use, quota consumption, loss, or charges resulting from a leaked, stolen, or compromised key, except to the extent caused by our breach of a duty or liability that applicable law does not allow us to exclude or limit.

Disconnecting the key in myoxin removes the usable stored key from our active systems. Revoking it in Google AI Studio is the definitive way to invalidate it everywhere. If the key is absent, invalid, rate-limited, or exhausted, AI features may pause or run late; a bring-your-own-key account will not silently fall back to a myoxin-hosted key.

7. Subscriptions, Billing, And Refunds

Some features may require a paid subscription. Pricing, trials, entitlements, renewals, billing cadence, and cancellation terms may be presented in-app, through the relevant app store, or through a subscription platform such as RevenueCat.

  • Where you purchase through Apple App Store or Google Play, those platforms control billing, renewals, cancellations, and many refund rules.
  • We may change pricing, plans, feature limits, or packaging at any time for future periods.
  • If a payment fails, we may downgrade, pause, or terminate paid access.

8. Your Content And License

You retain ownership of content you submit, such as workout entries, profile information, messages, notes, images, voice notes, and other inputs ("Your Content"). You grant us a non-exclusive, worldwide, royalty-free license to host, store, reproduce, modify, transmit, analyze, and otherwise use Your Content as reasonably necessary to provide, secure, support, enforce, and improve the Services, subject to the Privacy Policy.

You represent that you have the rights needed to submit Your Content and that doing so does not violate law or the rights of others. This includes any photo, video, or voice note you choose to attach to a scientist-chat message: you are responsible for only sharing attachments you have the right to share, and for being mindful of any other person who may be identifiable in that content, including anything that reveals their health information, before you send it.

9. Acceptable Use

You may not:

  • Use the Services unlawfully or in a way that infringes, harasses, threatens, abuses, or exploits others.
  • Attempt to reverse engineer, scrape, overload, probe, bypass, or interfere with the Services, accounts, models, APIs, security controls, or rate limits.
  • Upload malware, spam, deceptive content, or content you do not have rights to provide.
  • Attach or share a photo, video, voice note, or other content that includes another identifiable person, or that reveals another identifiable person's information (including their health information), without that person's consent.
  • Use the Services to create medical, legal, safety-critical, or other high-risk decisions without appropriate independent review.
  • Use the Services for competitive benchmarking, model extraction, or unauthorized commercial exploitation without our written permission.

10. Third-Party Services

The Services may interoperate with or depend on third-party services, including app stores, health platforms, AI providers, hosting providers, messaging providers, and subscription platforms. We do not control those third parties and are not responsible for their separate products, outages, billing behavior, privacy practices, or terms.

11. Suspension And Termination

We may suspend, restrict, or terminate access to all or part of the Services at any time if we believe it is necessary to protect users, the Services, third parties, or our rights; to investigate abuse; to comply with law; for non-payment; or for breach of these Terms.

You may stop using the Services at any time. Deleting the app or disconnecting an integration does not automatically delete your account or server-side data.

12. Intellectual Property

The Services, excluding Your Content, are owned by us or our licensors and are protected by intellectual-property and other laws. Except for the limited right to use the Services under these Terms, no rights are granted to you.

13. Disclaimers

To the fullest extent permitted by law, the Services are provided "as is" and "as available" without warranties of any kind, express, implied, statutory, or otherwise.

  • We disclaim warranties of merchantability, fitness for a particular purpose, non-infringement, title, accuracy, quiet enjoyment, and that the Services will be uninterrupted, secure, or error-free.
  • We do not warrant that logs, analytics, syncs, reminders, coach outputs, integrations, billing flows, or third-party channels will always function correctly or at all.
  • We do not guarantee any training, physique, strength, performance, recovery, health, or business outcome.

14. Limitation Of Liability

To the fullest extent permitted by law, we will not be liable for any indirect, incidental, special, exemplary, punitive, or consequential damages, or for loss of profits, revenue, data, business, goodwill, or opportunities, arising out of or relating to the Services.

To the fullest extent permitted by law, our aggregate liability for all claims arising out of or relating to the Services will not exceed the greater of (a) the amount you paid us for the Services in the 12 months before the event giving rise to the claim, or (b) EUR 100.

Nothing in these Terms excludes or limits liability that cannot lawfully be excluded or limited, including where applicable liability for fraud, willful misconduct, gross negligence, or death or personal injury caused by negligence.

15. Indemnity For Non-Consumer Misuse

If you use the Services for business purposes, or if your unlawful or prohibited conduct causes claims or losses for us, you will defend, indemnify, and hold us harmless from related third-party claims, damages, liabilities, and reasonable costs, to the extent permitted by law.

16. Consumer-Law Savings; Governing Law

These Terms are governed by the laws of the Netherlands, excluding conflict-of-law rules. If you are a consumer, mandatory protections of the country where you habitually reside continue to apply to the extent they cannot lawfully be waived.

Subject to mandatory consumer rights, disputes will be brought in the competent courts of the Netherlands. If mandatory law gives you the right to bring a claim elsewhere, that right is not waived.

17. Changes To These Terms

We may update these Terms at any time. The updated Terms will apply when posted, unless law requires additional notice. If you continue using the Services after updated Terms become effective, you accept them.
