Terms of Service

Last updated: 7 November 2026

These Terms of Service (“Terms”) govern your access to and use of Cortix (the “Service”), provided by Cortix AS, a private limited company registered in Norway, organisation number 938 652 260 (“we”, “us”, “Cortix”). By creating an account or using the Service, you accept these Terms. If you do not accept them, do not use the Service.

1. Eligibility

You must be at least 16 years old to use the Service. By creating an account, you represent that you meet this minimum age and that you are physically able to participate in the training activities described. The Service is not intended for medical use or for users who have been advised by a medical professional to avoid physical exercise.

2. Your account

• You are responsible for keeping your login credentials confidential and for all activity under your account.
• You must provide accurate information during registration and keep it up to date.
• You must not share your account with anyone else or allow others to use it.
• Notify us immediately at support@cortix.no if you suspect unauthorised use of your account.

3. Third-party services

The Service integrates with third-party services, including fitness platforms such as Strava and service providers for hosting, artificial intelligence, analytics, payment processing, and email delivery. When you connect a third-party account, you authorise us to access and import the data you have consented to share. Your use of these third-party services is governed by their own terms and privacy policies. We are not responsible for the availability, accuracy, or behaviour of third-party services.

4. Subscription, pricing, and payment

Cortix is a paid subscription, billed monthly or yearly. You can buy it on our website, where Stripe handles the payment, or in the iPhone or Android app, where Apple or Google handles it.

• Free week. A new subscriber gets the first 7 days free, once per person. Cancel before the week ends and you are not charged. Otherwise the first payment is taken when the week ends.
• The price, in the currency of your checkout or store and including any VAT, is shown before you confirm.
• Each billing period is paid at its start.
• Card details are handled by Stripe, Apple or Google and never stored by us.
• A price change applies from your next billing period, and we tell you before it does.

5. Right of withdrawal

If you live in the EU or EEA and bought your subscription on our website, you can withdraw within 14 days of signing up by emailing support@cortix.no. You pay for the days you used before withdrawing, and we refund the rest. A subscription bought in the App Store or Google Play is refunded by Apple or Google under their own rules: ask them through your store account.

6. Automatic renewal and cancellation

Your subscription renews automatically at the end of each billing period, at the price then in force, until you cancel.

You can cancel at any time. Bought on our website: in Settings, under Subscription. Bought in the app: in your App Store or Google Play subscription settings. Deleting your Cortix account does not cancel a subscription bought in the App Store or Google Play. Cancelling takes effect at the end of the current billing period and you keep access until then. We do not refund the unused part of a period, except as described in section 5 or required by law.

7. Service availability

We aim to keep the Service operational at all times but do not guarantee uninterrupted availability. Scheduled maintenance, third-party outages, and unforeseen events may cause interruptions.

If the Service is materially unavailable or materially defective for more than seven (7) consecutive days due to our fault, you may request a pro-rata credit or refund for the affected period by emailing support@cortix.no. This is in addition to, and does not limit, your statutory rights as a consumer.

8. Acceptable use

You agree not to:

• Use the Service for any unlawful purpose or in violation of these Terms
• Attempt to reverse-engineer, scrape, or automate access to the Service beyond what is offered through its official interface
• Upload or generate content that is harassing, defamatory, hateful, or violates another person’s rights
• Use the Service to train other AI models or redistribute AI-generated output as your own product
• Disrupt, overload, or interfere with the Service’s infrastructure
• Circumvent rate limits, quotas, or access controls

We may suspend or terminate accounts that violate these rules, with or without notice, at our reasonable discretion.

9. Your content

You retain ownership of the data you provide (workout logs, notes, goals, messages). You grant Cortix a worldwide, non-exclusive, royalty-free licence to host, process, and display this content for the purpose of operating and providing the Service to you, and, only if you opt in, to train Cortix's own coaching models without your name or email, as the Privacy Policy describes.

Content you post on the public feedback board may be visible to other users. It is deleted with your account.

10. Intellectual property

The Service, including its source code, design, branding, and content, is owned by Cortix and protected by intellectual property laws. These Terms do not grant you any rights to use the Cortix name or logo without our prior written permission.

11. Training and medical disclaimer: please read carefully

Endurance training involves inherent risks, including but not limited to muscle strain, cardiovascular events, falls, injury, and in rare cases death. By using the Service, you acknowledge and agree that:

• You are voluntarily participating in physical activity at your own risk.
• You will consult a qualified medical professional before starting or substantially changing your training programme, particularly if you have any pre-existing medical conditions, cardiovascular concerns, are pregnant, recovering from injury or illness, or are taking medication.
• You are responsible for monitoring your own physical response to training and stopping immediately if you experience pain, dizziness, shortness of breath, chest discomfort, or any other warning signs.
• The Service’s recommendations are based on the data you provide and automated model outputs, which may be incomplete, inaccurate, or unsuitable for your circumstances.
• You will use your own judgement and consult qualified professionals before acting on any recommendation from the Service.

12. AI-generated content

Training plans, coach messages, and analytics summaries are generated by large language models. These outputs can contain errors, inconsistencies, or hallucinations. We make no guarantee as to their accuracy, completeness, safety, or suitability for your individual needs. Treat all AI output as a starting point for your own judgement, not as authoritative advice.

13. No warranty

To the maximum extent permitted by applicable law, the Service is provided “as is” and “as available”, without warranties of any kind, express or implied, including without limitation any implied warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy, or availability. We do not warrant that the Service will be uninterrupted, error-free, or secure.

Nothing in this section affects your mandatory consumer rights under applicable law.

14. Limitation of liability

To the maximum extent permitted by applicable law:

• Cortix is not liable for any injury, illness, medical condition, death, or other harm resulting from your participation in physical activity, whether or not related to recommendations made by the Service.
• Cortix is not liable for any indirect, incidental, special, consequential, or punitive damages, including lost profits, lost data, or loss of goodwill, arising out of or in connection with your use of the Service.
• Our total aggregate liability for any direct damages arising out of or in connection with the Service is limited to the greater of: (a) the total amount you paid us in the twelve (12) months preceding the event giving rise to the claim; or (b) 500 NOK.

Nothing in these Terms limits liability that cannot be limited under Norwegian law, including liability for gross negligence, wilful misconduct, or personal injury caused by our intentional or grossly negligent acts, or your mandatory statutory rights as a consumer.

15. Indemnity

You agree to indemnify and hold Cortix harmless against third-party claims arising out of (a) your wilful misconduct or gross negligence in using the Service, (b) your violation of these Terms, (c) your violation of the rights of any third party, or (d) content you submit or generate through the Service. This indemnity does not extend to matters where indemnification is not permitted against consumers under Norwegian law.

16. Force majeure

Neither party is liable for failure or delay in performance caused by events beyond its reasonable control, including natural disasters, war, terrorism, labour disputes, government actions, internet or telecommunications outages, third-party service failures, or cyberattacks. The affected party will notify the other and make reasonable efforts to resume performance.

17. Changes to the Service

We may modify, suspend, or discontinue any part of the Service at any time. We will give reasonable notice of material changes that negatively affect paying subscribers. If we permanently discontinue the Service, we will attempt to give you reasonable notice and a way to export your data.

18. Termination

You may delete your account at any time from your settings, subject to the cancellation terms in sections 5 and 6. We may suspend or terminate your access to the Service if you materially breach these Terms or if we are required to do so by law. Sections 8 through 15, 20, and 21 survive termination of these Terms.

19. Changes to these Terms

We may update these Terms from time to time. The “Last updated” date at the top reflects the most recent change. We will notify you of material changes by email or in-app notice at least 30 days before they take effect for existing subscribers. If you do not accept the updated Terms, you may cancel your subscription before they take effect. Continued use of the Service after changes take effect indicates your acceptance of the updated Terms.

20. Governing law and disputes

These Terms are governed by the laws of Norway. Any dispute arising from these Terms or from your use of the Service shall be resolved in Norwegian courts, with the District Court in the jurisdiction of our registered address as the venue for first instance, unless mandatory consumer-protection rules provide otherwise.

Before filing a formal dispute, please contact us at support@cortix.no. Most issues can be resolved directly. As a consumer in Norway you may also refer disputes to the Norwegian Consumer Authority or the EU Online Dispute Resolution platform at ec.europa.eu/consumers/odr.
