Last updated: May 13, 2026

1. Agreement to Terms

These Terms and Conditions ("Terms") constitute a legally binding agreement between you and Robin Kirkestuen Melby, an individual operating under the trade name "Zet" ("Zet," "we," "us," or "our"), based in Skjåk, Innlandet, Norway.

These Terms govern your access to and use of the Zet mobile application ("Service"). By creating an account or using the Service, you agree to be bound by these Terms. If you do not agree, do not use the Service.

2. Eligibility

You must be at least 13 years old to use Zet. By using the Service, you represent that you are at least 13, or that you have parental/guardian consent if you are between 13 and 18 (or the age of majority in your jurisdiction).

The Service is intended for personal use only, not for internal business use.

3. The Service

Zet is a mobile workout tracking application that lets users log workouts, track progression, and receive AI-powered coaching suggestions. The AI features are powered by Anthropic's Claude.

AI Disclaimer. AI-generated coaching is for general fitness guidance only. It is NOT medical, professional training, or healthcare advice. Do not rely on the AI coach for medical decisions or training decisions involving serious injury, illness, or significant health concerns. Always consult a qualified professional.

4. Accounts

You must create an account to use the Service. You can sign up using email and password, Sign in with Apple, or Sign in with Google.

You are responsible for keeping your credentials secure and for all activity under your account. Notify us immediately at support@getzet.app if you suspect unauthorized access.

You may not sell, transfer, or share your account with anyone else.

5. Subscription, Trial, and Payment

The Service is offered as a paid subscription with the following plans:

Monthly: $9.99 USD per month
Annual: $79.99 USD per year

Each new account receives a 7-day free trial. After the trial, your selected subscription begins and renews automatically (monthly or annually, depending on your plan) at the listed price.

Payment processing. All payments are processed by Apple through the Apple App Store. We do not have access to your payment card details. By subscribing, you also agree to Apple's billing terms.

Auto-renewal. Subscriptions automatically renew at the end of each billing cycle unless you cancel at least 24 hours before the end of the current period, per Apple's standard subscription rules.

Price changes. We may adjust subscription prices. Material price changes will be communicated to you in advance, and you will have the opportunity to cancel before the new price takes effect.

6. Cancellation and Refunds

You can cancel your subscription at any time through iOS Settings → Apple ID → Subscriptions → Zet. Cancellation takes effect at the end of the current billing period; you retain access until then.

Refunds. Refunds are handled exclusively by Apple under their App Store policy. We do not directly issue refunds. To request a refund, visit https://reportaproblem.apple.com.

7. User Content

You retain ownership of all workout logs, coach messages, and other content you create in the Service ("User Content").

By using the Service, you grant us a worldwide, non-exclusive, royalty-free license to host, process, and display your User Content solely for the purpose of providing and improving the Service. This includes sending workout history and coach messages to Anthropic for the purpose of generating AI coach responses.

12. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW:

(a) IN NO EVENT WILL OUR TOTAL AGGREGATE LIABILITY TO YOU FOR ALL CLAIMS ARISING FROM OR RELATED TO THESE TERMS OR THE SERVICE EXCEED THE GREATER OF (i) THE AMOUNT YOU HAVE PAID US IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (ii) USD $50.

(b) IN NO EVENT WILL WE BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, INCLUDING LOSS OF PROFITS, DATA, USE, GOODWILL, OR OTHER INTANGIBLE LOSSES.

13. Indemnification

You agree to indemnify and hold harmless Robin Kirkestuen Melby and Zet from any claims, damages, losses, liabilities, and expenses (including reasonable attorney fees) arising from: (a) your use of the Service, (b) your violation of these Terms, (c) your User Content, or (d) your violation of any third-party right.

14. Term and Termination

These Terms remain in effect while you use the Service. You may terminate your account at any time by deleting it within the app or contacting us at support@getzet.app.

We may suspend or terminate your access without notice for breach of these Terms, suspected fraud, abuse, or any conduct we believe poses a risk to other users or the Service.

Upon termination, your right to use the Service ceases immediately. Sections 7 (license), 9 (intellectual property), 11 (disclaimers), 12 (limitation of liability), 13 (indemnification), 15 (governing law), and 16 (dispute resolution) survive termination.

15. Governing Law

These Terms are governed by the laws of Norway, without regard to conflict-of-law principles. Nothing in these Terms limits any mandatory consumer rights you may have under the laws of your country of residence.

16. Dispute Resolution

Informal negotiation. Before initiating any formal proceeding, you agree to first attempt to resolve any dispute by contacting us at support@getzet.app. Both parties agree to negotiate in good faith for at least thirty (30) days before pursuing arbitration.

Binding arbitration. If informal negotiation fails, any dispute arising out of or related to these Terms or the Service shall be resolved through binding arbitration administered in Oslo, Norway, conducted in English, under the rules of the Norwegian Arbitration Act (Voldgiftsloven). The decision of the arbitrator is final and binding.

Class action waiver. You and we agree that disputes will be resolved on an individual basis only, and not as a class, consolidated, or representative action.

Exceptions. Nothing in this section prevents either party from seeking injunctive relief in court for intellectual property infringement or other urgent matters.

17. Updates to These Terms

We may update these Terms from time to time. For material changes, we will notify you by email (sent from support@getzet.app) before the changes take effect. You will have the opportunity to review the updated Terms and, if you disagree, to terminate your account before the new Terms apply. Continued use of the Service after the effective date constitutes acceptance of the updated Terms.

18. Miscellaneous

Entire agreement. These Terms, together with our Privacy Policy, constitute the entire agreement between you and us regarding the Service.

Severability. If any provision is found unenforceable, the remaining provisions remain in effect.

No waiver. Our failure to enforce any provision is not a waiver of our right to do so later.

Assignment. You may not assign your rights under these Terms without our written consent. We may assign our rights and obligations without restriction.

Notices. Notices to us must be sent to support@getzet.app. Notices to you will be sent to the email associated with your account.
