Terms of Use

1. About these Terms

These Terms of Use ("Terms") are an agreement between you and Dejan Horvat, an individual developer based in the Republic of Serbia ("Nuvela", "we", "us"). They cover your use of the Nuvela mobile apps, the website gonuvela.com, and related services (together, the "Service"). By creating an account or using the Service, you agree to these Terms and to the processing described in our Privacy Policy at https://gonuvela.com/privacy. If you do not agree, please do not use the Service.

2. Who can use Nuvela

• You must be at least 18 years old and able to enter into a binding contract.
• You may not use the Service where the law forbids it.
• One person per account. Accounts may not be shared.

3. Your account

• To use Nuvela you need an account. You can create one with Sign in with Apple, Sign in with Google, or your email address and a one-time code.
• Give accurate information, and keep access to your sign-in method secure. You are responsible for what happens under your account.
• If you think someone else has accessed your account, tell us at once at [email protected].

4. The Service

• Nuvela builds a weekly training plan from your answers, equipment and feedback. It uses fixed training rules and suggests exercises, sets, reps and loads.
• The Service includes exercise demonstration videos with AI-generated coaches (section 8). It also offers optional equipment detection from a photo (section 8).
• We may improve, change, add or remove features. If we remove a core paid feature during a period you have paid for, we will tell you in advance where possible. Your statutory rights are not affected.

5. Your first week

• New accounts get 7 days of full access at no charge (the "First Week"). The First Week starts when you create your account.
• No payment details are needed for the First Week, and nothing is charged automatically when it ends. The First Week is tracked by our server, not by Apple or Google. It is not a store free trial.
• When the First Week ends, you need a Nuvela Pro subscription (section 6) to keep using the training features. Your account, your saved workouts and history, downloading your data, deleting your account, and subscribing or restoring a purchase stay available without one. A workout already under way when the First Week ends can still be finished and saved.
• There is one First Week per person. We may refuse a new First Week where an account appears to have been created to obtain repeat free periods.
• We may change or end the First Week for new users in the future, for example by replacing it with an introductory offer from the App Store or Google Play. The terms of any such offer are shown before you accept it. A First Week that has already started is not shortened.

6. Subscriptions (Nuvela Pro)

6.1 Purchase. Nuvela Pro is sold as an auto-renewing subscription, monthly or yearly, through Apple's App Store (iPhone) or Google Play (Android). The price, the billing period and any taxes are shown in the app and on the store's payment sheet before you confirm. Payment is charged to your Apple Account or Google account when you confirm the purchase. We never receive your card details.

6.2 Auto-renewal. Your subscription renews automatically for the same period at the then-current price unless you cancel it.

• App Store: auto-renewal must be turned off at least 24 hours before the end of the current period. Your account is charged for renewal within the 24 hours before the current period ends.
• Google Play: you can cancel any time before the renewal date.

6.3 How to cancel or manage.

• iPhone: Settings → your name → Subscriptions, or https://apps.apple.com/account/subscriptions
• Android: Google Play → profile icon → Payments & subscriptions → Subscriptions, or https://play.google.com/store/account/subscriptions
• The app also links to these pages: You → Subscription → Manage or cancel.
• Deleting the app or your Nuvela account does not cancel your subscription.
• After you cancel, Nuvela Pro stays active until the end of the period you have paid for. You are not charged again.

6.4 Refunds. Apple and Google process all payments for Nuvela Pro, so refunds are handled by them under their own policies. We cannot issue refunds for store purchases ourselves.

• Apple: https://reportaproblem.apple.com
• Google: https://support.google.com/googleplay/answer/2479637

Nothing in these Terms limits any mandatory right you have under consumer law where you live, including any statutory right of withdrawal. For store purchases, such rights are exercised through the store's process.

6.5 Price changes. If the price of your subscription changes, Apple or Google will tell you in advance and, where the law or the store requires it, ask for your consent. If you do not agree, you can cancel before the new price applies.

6.6 Switching plans and restoring purchases. You can switch between monthly and yearly through the store's subscription settings. The store decides when the switch takes effect. You can restore an existing subscription with Restore purchases, which is on the paywall and in You → Subscription.

6.7 Your subscription on your devices. Your subscription is tied to your Nuvela account. It unlocks Nuvela Pro when you are signed in to that account on any supported device, including a device on the other platform. To check confirm cross-platform entitlement through RevenueCat app user ID = our user ID

7. Health and safety — please read

• Nuvela is not medical advice and is not a medical device. It does not diagnose, treat, cure, monitor or prevent any disease or condition. It does not replace a doctor, physiotherapist or qualified trainer.
• Talk to a doctor before you start or change an exercise programme. This is especially important if you are pregnant or recently gave birth, have heart, lung, joint, bone or other health conditions, are recovering from an injury or surgery, take medication, or have not exercised for a long time.
• Stop at once if you feel pain, chest pain or pressure, dizziness, faintness, unusual shortness of breath, or anything else that worries you. Get medical help if you need it. In an emergency, call your local emergency number.
• Features such as "go easy on" areas and "this hurts" reports change which exercises are suggested. They do not assess, diagnose or treat anything.
• Suggested loads, reps and rest times are estimates. Choose weights you can control with good form. Warm up. Use a spotter where needed. Make sure your space and equipment are safe and in good condition.
• You exercise at your own risk and within your own limits. Results vary, and we do not promise any particular result.

8. AI-generated content

• Our coaches are AI-generated. Elena, Marcus and any other Nuvela coaches are fictional personas. Their faces, bodies, voices and videos are created with generative AI. They are not real people and not licensed or certified professionals. The app labels them "AI coach".
• Exercise demonstrations are AI-generated. We review them, but they may contain small visual inaccuracies. Follow the written cues and your own judgement. When in doubt, choose a simpler variation.
• Equipment detection uses AI and can be wrong. Your equipment list changes only after you confirm it.
• AI-generated content is provided for general fitness guidance and is no substitute for in-person instruction.

9. Your content and data

• You keep all rights to the content you add, such as workout logs, notes and photos ("Your Content").
• You give us a non-exclusive, worldwide, royalty-free licence to host, store, process and display Your Content only to provide the Service to you. This licence ends when you delete Your Content or your account, except for the retention described in the Privacy Policy.
• The Privacy Policy explains how we handle personal data, including health information. You can export or delete your data in the app at any time.

10. Acceptable use

You agree not to:

• break the law or anyone's rights, including by uploading photos of other people without their permission;
• reverse engineer, decompile or try to extract source code, except where the law expressly allows it;
• access the Service by automated means (bots, scrapers), overload it, probe its security, or get around access controls or the paywall;
• create several accounts to get repeat First Weeks, or share, resell or rent access;
• copy, redistribute or reuse our content, including coach videos and images, outside the app;
• use the Service to build a competing product, or to train AI models.

11. Our intellectual property

The Service and all its content, including software, the plan engine, exercise text, AI coach characters, images, videos, and the Nuvela name and logo, belong to us or our licensors. We grant you a personal, non-exclusive, non-transferable, revocable licence to use the app on devices you own or control, for your own non-commercial use, under these Terms and the rules of the store you got it from.

12. Changes to these Terms

We may update these Terms, for example when we add features or when the law changes. If a change is material, we will tell you in the app or by email at least 14 days before it takes effect. If you do not agree, you can stop using the Service and cancel your subscription before the change applies. Changes do not apply to disputes that arose before them.

13. Suspension and termination

• You can stop using Nuvela and delete your account at any time (You → Account and data → Delete account). Remember to cancel your subscription in the store (section 6.3).
• We may suspend or close your account if you seriously or repeatedly break these Terms, if the law requires it, or to protect the Service or other users. Where reasonable, we will warn you first and explain why.
• If we close the Service for everyone, we will give at least 30 days' notice in the app where possible. We will help you request a refund from Apple or Google for any unused prepaid period, or give one where the law requires it.

14. Disclaimers

We work hard to keep Nuvela useful and reliable. However, to the extent the law allows, the Service is provided "as is" and "as available". We give no warranty that it will be uninterrupted, error-free, or suitable for a particular purpose. This does not affect warranties or rights you have under mandatory consumer law that cannot be excluded.

15. Limitation of liability

To the extent the law allows:

• We are not liable for indirect, incidental, special or consequential losses, or for loss of profits, data or goodwill.
• Our total liability for all claims relating to the Service is limited to the greater of (a) the amount you paid for Nuvela Pro in the 12 months before the claim, or (b) USD 50.

These limits do not apply to liability that cannot be limited or excluded by law. That includes liability for death or personal injury caused by our negligence, for fraud, and for gross negligence or wilful misconduct. If you are a consumer in the EU, the UK, or another country that gives you mandatory rights, these limits apply only as far as your local law permits.

16. Governing law and disputes

These Terms are governed by the laws of the Republic of Serbia. However, if you are a consumer, you keep the protection of the mandatory laws of the country where you live, and you may bring a claim in the courts there where the law allows it. Before going to court, please contact us at [email protected]. Most problems can be solved quickly.

17. General

• If any part of these Terms is found invalid, the rest stays in force.
• If we do not enforce a right, we have not waived it.
• You may not transfer your rights under these Terms. We may transfer them, for example to a company Dejan Horvat sets up to run Nuvela, as long as your rights are not reduced. We will tell you if this happens.
• These Terms, the Privacy Policy, and (on iOS) Apple's Standard EULA are the whole agreement about the Service.

18. Additional terms for the Apple App Store (iOS)

If you downloaded Nuvela from Apple's App Store:

1. These Terms are between you and Dejan Horvat only, not Apple. Apple is not responsible for the app or its content.
2. Your licence to use the app is limited to Apple-branded products you own or control, as allowed by the Usage Rules in Apple's Media Services Terms and Conditions. Family Sharing does not apply to Nuvela Pro. To fill in keep Family Sharing off in App Store Connect
3. We, not Apple, are solely responsible for maintenance and support of the app ([email protected]). Apple has no obligation to provide maintenance or support for it.
4. If the app fails to meet an applicable warranty, you may notify Apple, and Apple will refund the purchase price of the app, if any. To the maximum extent permitted by law, Apple has no other warranty obligation for the app. Any other claims, losses, liabilities, damages, costs or expenses caused by a failure to meet a warranty are our responsibility, to the extent the law does not exclude them.
5. We, not Apple, are responsible for addressing any claims by you or a third party relating to the app or your use of it. That includes product liability claims, claims that the app fails to meet legal or regulatory requirements, and claims under consumer protection, privacy or similar laws.
6. If a third party claims that the app or your use of it infringes their intellectual property rights, we, not Apple, are solely responsible for the investigation, defence, settlement and discharge of that claim.
7. You confirm that you are not located in a country subject to a U.S. Government embargo or designated as a "terrorist supporting" country, and that you are not on any U.S. Government list of prohibited or restricted parties.
8. Contact for questions, complaints or claims: Dejan Horvat, Gruje Dedića 22, 25000 Sombor, Serbia, [email protected].
9. When using the app you must comply with applicable third-party terms, such as your mobile carrier's terms.
10. Apple and its subsidiaries are third-party beneficiaries of these Terms. Once you accept these Terms, Apple has the right, and is deemed to have accepted the right, to enforce them against you as a third-party beneficiary.

Apple's Standard EULA also applies to the app on iOS: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/. If it conflicts with these Terms about your licence to the iOS app, Apple's Standard EULA wins. On everything else, including the Service, subscriptions, the First Week and health and safety, these Terms apply.

19. Google Play (Android)

If you downloaded Nuvela from Google Play, Google Play's Terms of Service and policies also apply to your download and to purchases made through Google Play billing. Google is not a party to these Terms and is not responsible for the app.
