Effective: 2026-05-01 · Last updated: 2026-05-01

1. Acceptance

By creating a GRYTT account or using the Service, you accept and agree to be bound by these Terms of Service (the "Terms") and our Privacy Policy. If you do not agree, do not use the Service.

2. Eligibility

You must be at least 18 years old, have legal capacity to enter into a binding contract, and not be barred from receiving services under US export controls or sanctions law. We verify age at signup. Accounts determined to belong to minors will be deleted.

3. Account

4. The Service

GRYTT is an AI-native fitness platform that delivers personalized coaching through a conversational interface powered by the Anthropic Claude API. The Service includes optional pairing with a human trainer, AI-generated workout, nutrition, and supplement plans, and progress tracking. Nothing delivered through the Service is medical advice.

5. Subscription Terms

The Service is offered on the following plans:

  • Client (mobile) — billed monthly via Apple In-App Purchase (iOS) or Google Play Billing (Android). Managed through your store's subscription settings.
  • Trainer — billed monthly via Stripe.
  • Enterprise — billed under custom contract.

5.1 Auto-renewal disclosure (Apple §3.1.2 / 5.1.1)

For client subscriptions purchased through Apple, the following auto-renewal disclosure applies:

  • Subscription title: GRYTT Client.
  • Length of subscription: 1 month.
  • Price per period: as displayed on the in-app subscription screen at the time of purchase, in your local currency.
  • Payment will be charged to your Apple ID account at confirmation of purchase.
  • Subscription automatically renews unless auto-renewal is turned off at least 24 hours before the end of the current period.
  • Your account will be charged for renewal within 24 hours prior to the end of the current period at the same price.
  • You can manage your subscription and turn off auto-renewal at any time from your Apple ID Account Settings after purchase.

5.2 Auto-renewal (Google Play and Stripe)

For Google Play subscriptions, auto-renewal is governed by Google Play Billing terms and managed in Google Play's Subscriptions settings. For Stripe subscriptions, auto-renewal continues until you cancel from the Stripe customer portal accessible in your account settings. In all cases, GRYTT will charge the renewal price published at the time of renewal.

6. Cancellation and Refunds

You may cancel at any time. For mobile client subscriptions, cancel through your Apple or Google subscription settings. For Stripe subscriptions, cancel from the Stripe customer portal in your account settings. Access continues until the end of the current billing period. We do not refund partial periods. Store-initiated refunds (Apple, Google) are governed by the respective store's policies; GRYTT will honor any refund decision the store communicates to us.

Pricing & Tax. Prices are displayed exclusive of applicable sales tax, VAT, or GST. Where required by law, we collect and remit tax via Stripe Tax based on the billing address you provide at checkout. Your final charge at checkout will show any applicable tax on a separate line. Mobile Apple and Google purchases include tax as determined by the respective store.

7. Acceptable Use

You agree not to:

  • Harass, threaten, defame, or impersonate any person.
  • Use the Service for any unlawful purpose or to facilitate unlawful activity.
  • Scrape, reverse-engineer, or attempt to circumvent our safety, age, or rate-limit controls.
  • Allow access to the Service by anyone under 18.
  • Use a client subscription for commercial coaching of third parties — that is the trainer tier's purpose.

8. AI-Generated Content Disclaimer

The GRYTT AI coach is a fitness assistant, not a medical professional. AI output is informational only and is not a substitute for professional medical, nutritional, or psychological advice. Consult a qualified physician before starting any new exercise, nutrition, or supplement program. Statements about supplements, dietary protocols, recovery from injury, or performance-enhancing substances are informational and never constitute a recommendation to obtain or use a controlled or regulated substance. GRYTT is not liable for outcomes from acting on AI-generated guidance.

9. Trainer–Client Relationships

Trainers on GRYTT are independent professionals. GRYTT acts as a platform facilitator and is not a party to the agreement between a trainer and their client. GRYTT is not liable for a trainer's coaching advice, programming choices, pricing, or conduct. Trainers are responsible for their own professional licensing, insurance, and tax obligations. Trainers indemnify GRYTT for any claim arising from their own coaching, programming, pricing, or conduct toward clients, in addition to any indemnification provided in §14.

10. User Content

You retain ownership of the content you submit to GRYTT (chat messages, body stats, workout logs, profile information, etc.). You grant GRYTT a worldwide, non-exclusive, royalty-free license to process your content for the sole purpose of operating the Service, including transmission to processors listed in our Privacy Policy. When you link to a trainer, you grant the trainer a license to view content you share with them. AI-derived summaries ("memories") may be retained as embeddings to personalize future sessions.

11. Intellectual Property

The GRYTT brand, software, AI personas, and platform content are the property of Sentravision, LLC and its licensors. We grant you a limited, non-exclusive, non-transferable license to use the Service for personal, non-commercial purposes (or, for trainers, to deliver coaching to your clients on the trainer plan).

12. Disclaimers

The Service is provided "as is" and "as available," without warranties of any kind, whether express or implied, including warranties of merchantability, fitness for a particular purpose, non-infringement, or uninterrupted operation. We do not warrant that AI output will be accurate, safe, or appropriate for your individual circumstances.

13. Limitation of Liability

To the fullest extent permitted by law, GRYTT's total liability for any claim arising out of or relating to the Service is capped at the greater of (a) one hundred US dollars (USD 100) or (b) the amount you paid GRYTT in the twelve months preceding the claim. GRYTT is not liable for indirect, incidental, consequential, special, or punitive damages. Carve-outs apply where non-waivable under law (gross negligence, willful misconduct, or death or personal injury).

14. Indemnification

You agree to indemnify and hold harmless GRYTT, its officers, employees, and affiliates from any claim, loss, or expense arising from your breach of these Terms or your misuse of the Service.

15. Dispute Resolution

These Terms are governed by the laws of the State of Delaware, without regard to conflict-of-laws principles. Any dispute arising out of or relating to these Terms will be resolved by binding individual arbitration administered by the American Arbitration Association under its Consumer Arbitration Rules, seated in your state of residence. You and GRYTT each waive the right to participate in a class action, class-wide arbitration, or representative action. You may opt out of this arbitration clause within 30 days of first creating your account by emailing legal@grytt.app. Disputes that qualify for small-claims court may proceed there.

EU/UK consumer carve-out. The arbitration agreement and class-action waiver above do not apply to consumers resident in the European Union or the United Kingdom. For those users, disputes are governed by the consumer's local courts and the mandatory consumer-protection law of their country of residence.

16. DMCA

GRYTT responds to clear notices of alleged copyright infringement. To submit a DMCA notice, email legal@grytt.app with the elements required by 17 U.S.C. §512(c)(3).

17. Termination

You may stop using the Service at any time. We may suspend or terminate your access for breach of these Terms, suspected fraud, or to comply with law. Sections that by their nature should survive termination (including §§10 license grant, 12 disclaimers, 13 liability, 14 indemnification, 15 disputes) will survive.

18. Changes

We may modify these Terms from time to time. Material changes will be announced via in-app banner and email. Your continued use of the Service after the effective date constitutes acceptance.
