Terms of Use

Effective date: 6 July 2026 Last updated: 30 July 2026

These Terms of Use ("Terms") govern your access to and use of Duewell (the "Service"), a product operated by Carelius Nexus AS (org. no. 937 872 305) ("Duewell", "we", "us", "our"), located in Oslo, Norway.

By creating an account or using the Service, you agree to these Terms. If you do not agree, do not use the Service.


1. What Duewell is

Duewell is a tool that helps freelancers and small businesses follow up on their own unpaid invoices. Based on information you provide, Duewell generates draft follow-up messages and a formal demand letter, escalating in tone across stages, written for you to review and send yourself.

Duewell drafts. You send. Duewell does not send any message to your clients or contact your clients on your behalf. Every message is generated for you to review, edit, and send from your own email or channels, at your own discretion. Any notification Duewell sends by email goes only to you, the account holder — never to your clients.

2. Not legal advice

Duewell is a drafting and organizational tool, not a law firm, and does not provide legal advice. The messages, demand letters, and any "next steps" or debt-recovery guidance the Service generates are general in nature, are not tailored to your specific legal situation, and are not a substitute for advice from a qualified lawyer in your jurisdiction.

Debt-collection, consumer-protection, and pre-action requirements vary by country and, in some countries, by state or region. You are responsible for determining what is lawful and appropriate in your and your client's jurisdiction. If you are unsure whether a message or action is appropriate, consult a lawyer before sending or acting.

3. Your responsibilities

You are solely responsible for:

You represent that you are pursuing payment of a debt owed to you as the creditor. Duewell is not a debt-collection agency and does not act as a third-party collector on your behalf.

4. No guarantee of payment or outcome

Duewell does not guarantee that using the Service will result in payment, in any particular response from a client, or in any specific outcome. The Service helps you communicate more effectively; it cannot compel anyone to pay.

5. Eligibility and your account

You must be at least 18 years old and able to form a binding contract to use the Service. You are responsible for keeping your account credentials secure and for all activity under your account. Notify us promptly at support@duewell.app if you believe your account has been compromised.

6. Subscriptions, pricing, and payment

Duewell offers a free tier and a paid subscription ("Premium").

EU/EEA consumers — right of withdrawal: if you are a consumer in the EU/EEA, you normally have a 14-day right to withdraw from a purchase of digital services. Because Premium provides immediate access to the Service, by subscribing you expressly request that we begin performance immediately and acknowledge that you thereby lose your statutory right of withdrawal once the service has begun. This does not affect the voluntary goodwill refund described above.

7. Prohibited use and abuse of the Service

You agree not to:

We do not monitor or review the messages you generate, and by design we do not see what you send to your clients. Where we become aware of use that violates these Terms, we may warn, suspend, rate-limit, or terminate your account and remove access, at our discretion and without refund. Serious or unlawful misuse may be reported to the relevant authorities.

8. Intellectual property

The Service, including its software, design, and branding, is owned by us and protected by intellectual-property laws. We grant you a limited, non-exclusive, non-transferable licence to use the Service for its intended purpose while your account is active.

The content you input (invoice details, client information) and the messages you generate for your own use remain yours. You grant us a limited licence to process that content solely to provide the Service to you (see the Privacy Policy).

9. Third-party services

The Service relies on third-party providers, including Stripe (payments), Blink (backend, authentication, and AI processing), and hosting and analytics providers. Your use of the Service is also subject to those providers' terms where applicable. We are not responsible for third-party services outside our control.

10. Disclaimers

The Service is provided "as is" and "as available", without warranties of any kind, whether express or implied, including any warranty of merchantability, fitness for a particular purpose, accuracy, or non-infringement, to the fullest extent permitted by law. We do not warrant that the Service will be uninterrupted, error-free, or that generated content will be accurate, appropriate, or effective for your situation.

Nothing in these Terms excludes or limits any liability that cannot lawfully be excluded or limited, including, for consumers, statutory rights that cannot be waived.

11. Limitation of liability

To the fullest extent permitted by law, we will not be liable for:

To the fullest extent permitted by law, our total aggregate liability arising out of or relating to the Service will not exceed the greater of (a) the amount you paid us in the twelve (12) months before the event giving rise to the claim, or (b) USD 100. Nothing in this section limits liability that cannot lawfully be limited to consumers under applicable Norwegian or EU/EEA consumer-protection law.

12. Indemnification

You agree to indemnify and hold us harmless from any claims, damages, losses, or costs (including reasonable legal fees) arising from your use of the Service, the content you send, your breach of these Terms, or your violation of any law or third-party right.

13. Termination

You may stop using the Service and delete your account at any time. We may suspend or terminate your access if you breach these Terms or use the Service unlawfully. On termination, your right to use the Service ends; provisions that by their nature should survive (including sections 2, 3, 4, 8, 10, 11, and 12) will survive.

14. Changes to these Terms

We may update these Terms from time to time. If we make material changes, we will notify you (for example, by email or in-app) and update the "Last updated" date. Continued use of the Service after changes take effect constitutes acceptance.

15. Governing law and disputes

These Terms are governed by the laws of Norway, without regard to conflict-of-law rules. For consumers in the EU/EEA, mandatory consumer-protection laws of your country of residence may still apply regardless of this clause. Disputes will be subject to the jurisdiction of the Norwegian courts, with Oslo District Court (Oslo tingrett) as the venue, except where applicable consumer law provides otherwise.
