Terms of service

Last updated: 7 June 2026.

These terms ("Terms") govern your access to the marketing website at karl-ai.se and any subdomains (the "Site"), the 30-day free trial of the Karl software, and any other free-of-charge services we make available here. Use of the paid Karl software is additionally governed by the End-User Licence Agreement ("EULA"); paid purchases are additionally governed by the Refund policy.

1. Who you are contracting with

The Site and the trial service are operated by Arvid Lindqvist, sole trader (enskild firma) registered in Sweden at Dag Hammarskjölds torg 9, 211 18 Malmö, Sweden. Swedish business identification number (organisationsnummer): 980509-5792. ("we", "us", "our"). Contact: contact@karl-ai.se.

2. Acceptance

By using the Site or requesting a trial you confirm that you have read, understood, and agreed to these Terms. If you do not agree, do not use the Site or the trial.

3. Eligibility

You must be at least 18 years old and legally able to enter into a contract. If you are using Karl on behalf of an organisation you confirm that you are authorised to bind that organisation to these Terms.

4. Trial licences

  • The trial entitles a single developer to use the Karl software at the Solo tier for thirty (30) calendar days from the date the licence is issued.
  • One trial per email address and per organisation. We may, at our reasonable discretion, decline trial requests that appear to be automated, fraudulent, or designed to circumvent this limit.
  • The trial is provided "as is" and without warranty. See Section 9 below.
  • At the end of the trial period the licence stops working and the Karl software reverts to a feature-limited "demo" mode. No charge is made and no payment information is collected.
  • Use of the Karl software during the trial is governed by the EULA.

5. Acceptable use

You agree that you will not:

  • interfere with or disrupt the Site or the trial-issuance service, including by sending automated requests at a volume or rate beyond ordinary human use;
  • attempt to gain unauthorised access to our infrastructure, accounts, or to other users' data;
  • use the Site or the trial to send spam, malware, phishing content, or material that is unlawful, infringing, or harmful;
  • reverse-engineer the trial endpoint or the licence-signing service in an attempt to forge or extend licences;
  • use the trial in a manner that violates the EULA (for example, using a trial licence for production deployment or for more than one developer); or
  • use the Site to scrape data, harvest contact addresses, or train machine-learning models on its content without our prior written permission.

6. Intellectual property

The Site, its content, the Karl name and logo, the trial-issuance service, and all related materials are owned by us or our licensors and are protected by intellectual-property laws. Nothing in these Terms transfers any such rights to you. Rights in the Karl software are granted to you under the EULA, not under these Terms.

7. Third-party services

Paid checkout is operated by Paddle.com Market Limited ("Paddle") as merchant of record. Your use of Paddle's checkout is governed by Paddle's own terms, available at paddle.com/legal/checkout-buyer-terms. We are not party to that agreement and are not responsible for Paddle's services.

8. Privacy

Our handling of personal data is described in the Privacy policy, which is incorporated into these Terms by reference.

9. Disclaimer of warranties

To the maximum extent permitted by applicable law, the Site and the trial are provided "as is" and "as available", without warranties of any kind, whether express, implied, or statutory, including without limitation any implied warranties of merchantability, fitness for a particular purpose, non-infringement, or uninterrupted or error-free operation.

This Section does not exclude or limit any warranty or right that cannot be excluded or limited under mandatory law (for example, certain rights of consumers under EU law).

10. Limitation of liability

To the maximum extent permitted by applicable law, we shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of profit, revenue, goodwill, business opportunity, or data, arising out of or in connection with your use of the Site or the trial, whether based in contract, tort, statute, or otherwise.

Our total aggregate liability to you in connection with the Site or the trial shall not exceed one hundred euro (EUR 100).

Nothing in these Terms limits or excludes liability that cannot lawfully be limited or excluded, including liability for intentional misconduct, gross negligence, or death or personal injury caused by negligence.

11. Indemnity

You agree to indemnify, defend, and hold us harmless from and against any claim, loss, damage, liability, cost, and expense (including reasonable legal fees) arising out of your breach of these Terms, your misuse of the Site or the trial, or your violation of applicable law or any third-party right.

12. Suspension and termination

We may suspend or terminate your access to the Site or the trial at any time if you breach these Terms or if we reasonably believe that doing so is necessary to protect the Site, our other users, or any third party.

13. Changes to the Site or to these Terms

We may update the Site or these Terms from time to time. Material changes will be announced on this page with a new "Last updated" date. Continued use of the Site after such an update constitutes acceptance of the revised Terms.

14. Governing law and venue

These Terms are governed by the laws of Sweden, excluding their conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods. Disputes arising out of or in connection with these Terms shall be brought exclusively before the competent courts of Sweden, with Stockholm District Court (Stockholms tingsrätt) as the court of first instance.

If you are a consumer domiciled in the EU/EEA, you retain the benefit of the mandatory consumer-protection rules of your country of residence, and you may also bring proceedings in the courts of that country.

15. Miscellaneous

  • Entire agreement. These Terms, together with the Privacy policy, the EULA, and the Refund policy, constitute the entire agreement between you and us regarding your use of the Site and the trial.
  • Severability. If any provision of these Terms is found unenforceable, the remaining provisions remain in full force and 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 or transfer your rights or obligations under these Terms without our prior written consent. We may assign these Terms in connection with a merger, acquisition, or sale of assets.
  • Language. The English version of these Terms is the binding version; any translation is provided for convenience only.
