Terms of Service

Last updated: April 27, 2026

EU Consumer Notice: Consumers in the EU/EEA have statutory rights under Directive 2011/83/EU on consumer rights and applicable national consumer protection laws. Nothing in these Terms limits or excludes those statutory rights. In the event of a conflict between these Terms and your statutory rights, your statutory rights prevail.

1. Who We Are

Nusli is an independent app studio based in Athens, Greece, developing mobile applications for iOS and Android. Our apps operate in the health, wellness, and lifestyle space. References to "Nusli", "we", "us", or "our" in these Terms refer to the Nusli studio and its developer. For enquiries, contact legal@nusli.app.

2. Acceptance of Terms

By downloading, installing, or using any Nusli application, you confirm that you have read, understood, and agree to be bound by these Terms of Service and our Privacy Policy. If you do not agree, you must not download or use our apps. These Terms apply to all Nusli apps listed at nusli.app, unless an individual app provides its own supplemental terms.

You must be at least 16 years of age to use our services. By accepting these Terms, you confirm that you meet this age requirement.

3. Licence to Use

Subject to your compliance with these Terms, Nusli grants you a limited, non-exclusive, non-transferable, revocable licence to download and use our apps on devices you own or control, for personal, non-commercial purposes only.

You may not:

4. Health and Medical Disclaimer

Nusli apps — including CycleStack and all other health or lifestyle apps in the Nusli portfolio — are personal tracking tools only. They are not medical devices, do not constitute medical advice, and are not a substitute for professional medical guidance, diagnosis, or treatment. Always consult a qualified healthcare professional before making any decisions about supplements, medications, or changes to your health regimen. You assume full responsibility for how you use information within our apps.

5. In-App Purchases and Subscriptions

Some Nusli apps offer optional premium features available through one-time purchases or recurring subscriptions ("Premium"). The following terms apply to all paid features:

6. Refund Policy

Because all payments are processed by Apple or Google, refund requests must be directed to them:

EU consumers: If you are an EU consumer and have purchased a digital service, you have a 14-day right of withdrawal under Directive 2011/83/EU. However, by commencing use of the app immediately after purchase, you acknowledge that the right of withdrawal may not apply once digital content delivery has begun with your explicit consent. This does not affect your right to a refund for technical faults or services not delivered as described.

If you are unable to obtain a refund through Apple or Google and believe you are entitled to one, contact us at support@nusli.app within 30 days of purchase and we will do our best to assist.

7. Intellectual Property

All content, source code, design, graphics, branding, trademarks, and other materials in our apps and website are the intellectual property of Nusli. All rights reserved. Nothing in these Terms grants you any rights in our intellectual property other than the limited licence in Section 3.

8. User Content

You retain ownership of all data and content you enter into our apps (such as supplement logs and tracking entries). By using our cloud sync features, you grant Nusli a limited, revocable licence to store and process that content solely for the purpose of delivering the service to you. We do not claim ownership of your personal data. You may export or delete your data at any time as described in our Privacy Policy.

9. Disclaimer of Warranties

To the fullest extent permitted by applicable law, Nusli apps and services are provided "as is" and "as available" without warranty of any kind, express or implied. We do not warrant that our apps will be uninterrupted, error-free, free of viruses or other harmful components, or that any defects will be corrected. We do not guarantee the accuracy, completeness, or suitability of any information provided within our apps.

Nothing in this section excludes any statutory rights you may have as a consumer under applicable EU or Greek law that cannot be excluded by contract.

10. Limitation of Liability

To the maximum extent permitted by applicable law, Nusli's total aggregate liability to you for any claim arising out of or in connection with these Terms or the use of our apps — whether in contract, tort (including negligence), breach of statutory duty, or otherwise — shall not exceed the greater of: (a) the total amount you paid to Nusli or through Apple/Google for the relevant app in the 12 months immediately preceding the claim; or (b) €50.

In no event shall Nusli be liable for any indirect, incidental, special, punitive, or consequential damages, including loss of data, loss of profit, loss of revenue, or loss of goodwill, even if Nusli has been advised of the possibility of such damages.

Important: Some jurisdictions — including EU member states — do not allow the exclusion or limitation of certain types of liability. In such cases, the above limitations apply only to the fullest extent permitted by the law of the relevant jurisdiction. Nothing in this section limits Nusli's liability for death or personal injury caused by negligence, fraud or fraudulent misrepresentation, or any other liability that cannot be limited by law.

11. Account Suspension and Termination

Nusli reserves the right to suspend or terminate your access to our apps and services, without prior notice or liability, if:

You may stop using our apps at any time. Upon termination of your account, your right to use the relevant app ceases. Data deletion following termination is governed by our Privacy Policy.

12. Third-Party Services and Links

Our apps and website may contain links to or integrations with third-party services (such as Apple Health, Google Fit, or external websites). We are not responsible for the content, privacy practices, or terms of any third-party service. Your use of third-party services is at your own risk and subject to their respective terms and privacy policies.

13. Changes to These Terms

We may update these Terms from time to time to reflect changes in our services, technology, or applicable law. Where changes are material, we will notify you through the app or via the email address associated with your account at least 14 days before the changes take effect. Continued use of our apps after the effective date constitutes your acceptance of the updated Terms. If you do not accept the new Terms, you must stop using the relevant app.

14. Governing Law and Jurisdiction

These Terms are governed by and construed in accordance with the laws of Greece and applicable European Union regulations. The courts of Athens, Greece shall have exclusive jurisdiction to settle any dispute arising out of or in connection with these Terms, subject to the following:

15. Dispute Resolution (EU)

If you are an EU consumer and have an unresolved complaint, you may use the European Commission's Online Dispute Resolution (ODR) platform: ec.europa.eu/consumers/odr. Our contact email for ODR purposes is legal@nusli.app. We are not obligated to participate in alternative dispute resolution proceedings, but we commit to making reasonable efforts to resolve disputes directly with you first.

16. Severability

If any provision of these Terms is found to be unenforceable or invalid under applicable law, that provision will be limited or eliminated to the minimum extent necessary, and the remaining provisions will continue in full force and effect.
