Terms of Service

Last updated: 2025-12-03

These Terms of Service (“Terms”) govern access to and use of the Nodon web application and related online services (the “Service”).

By creating an account, clicking “Sign up”, checking a box indicating acceptance, or accessing or using the Service, you acknowledge that you have read, understood, and agree to be bound by these Terms. If you do not agree, you must not use the Service.

If you have a separate written service agreement with Nodon (a “Service Agreement”), that agreement will apply. If there is a conflict between these Terms and a Service Agreement, the Service Agreement prevails for the relevant account or scope; these Terms apply to everything else.

1. Who we are

These Terms are between:

Nodono Technology AB (reg. no. 559289-3464),
Hantverkargatan 85, 112 38 Stockholm, Sweden
(“Nodon”, “we”, “us”, “our”)

and you as a user or customer of the Service (“Customer”, “you”).

If you use the Service on behalf of a company or other organisation (an “Organisation”), “you” also means that Organisation, and you represent and warrant that you have authority to bind that Organisation to these Terms.

2. Scope of the Service

2.1 What the Service does
Nodon provides a software-as-a-service platform for climate, energy, and cost simulations for construction and real-estate projects, and AI-assisted features.

2.2 Changes and improvements
 We may update or change the Service from time to time, for example to improve performance, add features, fix bugs, or adapt to legal or technical requirements. Changes that do not materially reduce the overall functionality may be made without notice. For material changes, we will give reasonable notice where practicable (e.g. in-app or by email).

2.3 Beta and trial features
 We may offer previews, betas, or experimental features (“Beta Features”). Beta Features are provided “as is”, may be changed or removed at any time, and may have reduced or different support and security assurances.

3. Accounts and Organisations

3.1 Account registration
 To use the Service, you must create an account and provide accurate, up-to-date information (such as name, email address, and Organisation). You are responsible for keeping this information current.

3.2 Eligibility
 The Service is intended for professional and business use. By using the Service, you confirm that:

  • you are at least 18 years old; and

  • if you use the Service on behalf of an Organisation, you are authorised to do so.

3.3 Login details and security
 You must keep your login details secure and not share them with others. You are responsible for all use of the Service under your account. Notify us promptly if you suspect unauthorised access or a security incident.

3.4 Authorised Users and licences
 User licences are individual and may only be used by one natural person each. You may allow your employees, consultants, and similar representatives (“Authorised Users”) to use the Service under your account. You are responsible for their actions and for ensuring that they comply with these Terms.

4. Plans, Fees and Payment

4.1 Free, trial and paid plans
 We may offer free, trial, and paid plans. Plan descriptions and prices are shown on our website, in the product, or in an Order Form / Service Agreement.

We may apply technical limits to the Service (such as storage, number of projects, or volume of AI requests) and change these from time to time.

For free or trial plans, we may modify or discontinue the plan, or deactivate accounts that have been inactive for an extended period, after reasonable notice where practicable.

4.2 Fees and billing
 For paid plans, you agree to pay the applicable fees (“Fees”). Fees are normally billed in advance (e.g. annually or monthly) and are exclusive of VAT and other applicable taxes. Invoices are payable within the period stated on the invoice. We may suspend access to the Service for non-payment.

4.3 Price changes
 We may change our prices in the future. New prices will apply from the start of the next billing period. We will notify you in advance. If you do not agree, you may cancel before the new prices take effect.

4.4 No refunds
 Except as required by law or expressly stated in a Service Agreement, Fees are non-refundable.

5. AI and LLM Features (including OpenAI)

5.1 AI Features
 The Service includes features that use artificial intelligence and large language models (“AI Features”). These may be provided by Nodon and/or by third-party AI providers (such as OpenAI and similar vendors) acting as our sub-processors (“AI Providers”).

5.2 What is processed
 When you use AI Features, the Service may send the following to AI Providers:

  • text or data you input (e.g. project descriptions, questions, material choices); and

  • necessary context to generate outputs (e.g. project parameters, settings).

AI Providers process this solely to provide AI outputs to you via the Service, under contracts with us and subject to applicable data-protection law. Further details are available on request and, where relevant, in our Data Processing Agreement (DPA).

5.3 Your responsibilities
 When using AI Features, you agree that:

  • you remain responsible for the content you input and how you use the outputs;

  • you will not intentionally input special categories of personal data (e.g. health data, political opinions, religion) or other highly sensitive data unless you have a lawful basis and have complied with all legal requirements;

  • you will not input data you are not allowed to share with Nodon or our AI Providers (for example, third-party trade secrets without permission).

5.4 AI is assistive, not professional advice
 AI-generated outputs may be incomplete, outdated, or incorrect. They do not replace professional judgment or legal, engineering, energy, climate, or financial advice. You must review and validate all AI outputs before using them in design decisions, external communication, or compliance documentation.

5.5 High-risk use
 You must not use AI Features for high-risk purposes where errors could lead to death, personal injury, major property damage, or significant environmental harm.

5.6 Improvement and analytics
 We may use aggregated and anonymised information about how AI Features are used (e.g. which features are used, volume of prompts) to maintain, secure, and improve the Service.

6. Customer Data and Privacy

6.1 Customer Data
 “Customer Data” means all data, files, documents, content, and information that you or your Users submit to or store in the Service, including project data, material selections, comments, and any personal data.

You retain all rights to Customer Data, subject to the rights granted to us in these Terms.

6.2 Licence to use Customer Data
 You grant Nodon a non-exclusive, worldwide, royalty-free licence to host, store, process, transmit, and display Customer Data as needed to:

  • provide, operate, and support the Service;

  • secure and maintain the Service;
    prevent abuse or address technical or security issues; and

  • comply with law and enforce these Terms.


6.3 Responsibility for Customer Data
 You are responsible for:

  • the accuracy, quality, and legality of Customer Data;

  • ensuring you have all rights and legal bases to submit Customer Data and grant the licence above; and

  • ensuring that Customer Data does not infringe any third-party rights or violate applicable law.


6.4 Personal data and DPA
Nodon is the controller for personal data we process about you when you create and use an account, such as name, contact details, login information, usage logs, and support communication. We process this personal data in order to:

(a) provide, operate, and secure the Service;

(b) manage your account and our relationship with you;

(c) handle billing, support, and communication; and

(d) analyse and improve the Service (including through analytics and error reporting tools).

Our legal bases for this processing include performance of our contract with you, compliance with legal obligations, and our legitimate interests in operating, securing, and improving the Service.

Where we process personal data as a processor on your behalf (for example, project data about your own customers or employees), this is governed by a separate Data Processing Agreement (“DPA”) which forms part of these Terms where applicable and is available on request. In case of conflict between these Terms and the DPA regarding personal data processing, the DPA prevails.

You may exercise your rights under applicable data protection law (including rights of access, rectification, erasure, restriction, portability, and objection) by contacting us.

6.5 Anonymised and aggregated data
 We may anonymise or aggregate Customer Data so that it can no longer be linked to an individual or to you. We own such anonymised or aggregated data and may use it for any lawful purpose, including statistics, benchmarks, research, and improving the Service.

7. Acceptable Use

You and your Users must not:

  • break the law when using the Service;

  • copy, modify, translate, or create derivative works of the Service (except where permitted by law and not waivable by contract);

  • reverse engineer, decompile, or attempt to extract source code, except where allowed by mandatory law;

  • bypass or attempt to bypass security or access controls;

  • use the Service to build a competing product;

  • upload malware or harmful code;

  • use the Service to send spam or unlawful marketing;

  • upload content that is illegal, infringing, defamatory, or otherwise unlawful; or

  • resell, rent, or provide the Service to third parties except as clearly allowed in a Service Agreement.


We may suspend or limit access if we reasonably believe there is a breach of this Section, a security risk, or unlawful activity. We will inform you where reasonable.

8. Intellectual Property and Feedback

8.1 Nodon’s IP
 Nodon and its licensors own all rights in and to the Service and related intellectual property (“Nodon IPR”), including software, code, algorithms, designs, user interfaces, templates, documentation, trademarks, and know-how.

Nothing in these Terms transfers ownership of Nodon IPR to you. You only receive the limited right to use the Service as described in these Terms.

8.2 No registration of similar marks
 You may not register or use any company name, product name, domain name, or other designation that is identical or confusingly similar to “Nodon” or our other trademarks.

8.3 Feedback
 If you provide ideas, suggestions, or feedback about the Service (“Feedback”), we may use it freely without restriction or obligation to you. We own all rights in such improvements.

9. Third-Party Services and Sub-processors

9.1 Third-party services
 The Service may integrate or interact with third-party services, applications, or tools (“Third-Party Services”), such as identity providers, communication tools, analytics, or AI Providers. Your use of Third-Party Services is governed by their own terms and privacy policies. We are not responsible for Third-Party Services.

9.2 Sub-processors
 We may use third-party sub-processors (including hosting, logging, analytics, support, and AI Providers) to process data on our behalf. A current list of key sub-processors is available in the DPA or on request. We remain responsible for our sub-processors’ performance towards you.

10. Availability, Maintenance and Security

10.1 Availability
 We aim to keep the Service available 24/7, with reasonable maintenance windows and subject to internet and infrastructure dependencies. We do not guarantee uninterrupted or error-free operation.

10.2 Maintenance
 We may perform planned maintenance (usually scheduled outside normal business hours where practicable). In urgent cases (e.g. security issues), we may perform emergency maintenance without prior notice.

10.3 Security
 We apply reasonable technical and organisational measures to protect the Service and Customer Data against unauthorised access, loss, or alteration. No system can be 100% secure, and you are responsible for maintaining appropriate backups and internal access controls.

11. Warranties and Disclaimers

11.1 Limited warranty for paying customers
 For paying Customers, Nodon will provide the Service with reasonable skill and care in accordance with these Terms and applicable documentation.

11.2 General disclaimers
 Except as expressly stated in these Terms or a Service Agreement:

  • the Service (including AI Features and Beta Features) is provided “as is” and “as available”;

  • we do not guarantee that the Service will be error-free, uninterrupted, or fit for your particular purpose;

  • we do not guarantee that calculations, AI outputs, or results are complete, correct, or sufficient for your legal, financial, engineering, or environmental obligations.

You are responsible for verifying results and using professional judgment.

  • business interruption or loss of business opportunities;

  • errors or omissions in AI outputs or calculated results, where you could reasonably review and verify them.

12.2 Mandatory law
 These limitations do not apply where liability cannot be limited or excluded under mandatory law (for example, in cases of intent or gross negligence, or for death or personal injury caused by negligence).

12.3 Indemnity
 You agree to indemnify and hold harmless Nodon and our officers, directors, and employees from any claims, losses, or damages arising out of (a) your or your Users’ breach of these Terms or applicable law, or (b) Customer Data that infringes third-party rights.

 These Terms apply from the moment you first access or use the Service and remain in force until your account is closed and all subscriptions have ended.

13.2 Your termination
 You may cancel your subscription or close your account at any time through the Service or by contacting us as described below. For paid plans, termination will take effect at the end of the current billing period, unless otherwise agreed in a Service Agreement.

13.3 Our suspension or termination

  • you fail to pay Fees after reminder;

  • we reasonably believe your use creates a security or legal risk; or

  • we decide to discontinue the Service.

For free or trial use, we may suspend or terminate at any time without cause.

13.4 Effect of termination
 After termination:

  • your right to use the Service ends;

  • we may delete or anonymise Customer Data after a reasonable retention period, except where law requires longer retention;

  • upon request and where technically feasible, we may provide you with an export of certain Customer Data in a standard format before deletion.


Fees already paid are not refunded unless required by law or expressly agreed in a Service Agreement.

14. Changes to these Terms

We may update these Terms from time to time. When we do, we will publish the updated version and change the “Last updated” date at the top. For material changes, we will provide reasonable notice (e.g. by email or in-product message).

If you continue to use the Service after the updated Terms take effect, you are deemed to accept them. If you do not agree, you must stop using the Service and close your account.

15. Governing Law and Disputes

15.1 Governing law
 These Terms are governed by and construed in accordance with Swedish law, without regard to its conflict-of-laws rules.

15.2 Arbitration (B2B)
 Any dispute, controversy, or claim arising out of or in connection with these Terms or the Service shall be finally settled by arbitration administered by the Arbitration Institute of the Stockholm Chamber of Commerce (SCC).

  • The SCC Rules for Expedited Arbitrations apply, unless the SCC decides that the Arbitration Rules shall apply in view of the complexity of the case, the amount in dispute, or other circumstances.

  • The seat of arbitration is Stockholm, Sweden.

  • The language of the arbitration is Swedish (or another language agreed in writing).


15.3 Consumers (if applicable)
 If you are considered a consumer under mandatory law, you may have the right to bring certain disputes before public courts instead of arbitration. Nothing in these Terms limits any mandatory consumer rights.

16. Confidentiality

16.1 Confidential Information

In connection with the Service, each party may receive non-public, confidential or proprietary information about the other party (“Confidential Information”). Confidential Information includes, for example, business plans, technical information, security information, pricing, product roadmaps, and Customer Data. It does not include information that (a) is or becomes publicly available without breach of these Terms, (b) was already lawfully known to the receiving party, (c) is independently developed without use of the Confidential Information, or (d) is received from a third party without a duty of confidence.

16.2 Use and protection

Each party must:

(a) use the other party’s Confidential Information only to fulfil these Terms; and

(b) protect the other party’s Confidential Information with at least reasonable care and not disclose it to any third party, except to its employees, contractors, or professional advisors who need to know it and are bound by confidentiality obligations at least as strict as those in this Section.

16.3 Required disclosures

A party may disclose Confidential Information if required by law, regulation, or court/authority order, but must (where lawful) give the other party prompt notice and request confidential treatment.

16.4 Duration

The confidentiality obligations in this Section survive termination of these Terms for as long as the information remains Confidential Information.

17. Miscellaneous

  • Entire agreement. These Terms, together with any applicable Service Agreement and DPA, form the entire agreement between you and Nodon regarding the Service.

  • Severability. If a provision is found invalid or unenforceable, the remaining provisions remain in force.

  • Assignment. You may not assign or transfer these Terms without our prior written consent. We may assign these Terms (e.g. in connection with a merger, acquisition, or corporate reorganisation).

  • No waiver. A failure to enforce a provision is not a waiver of the right to enforce it later.
