Terms of Service

Last updated: October 5, 2026

1. Agreement to these Terms

These Terms of Service ("Terms") form a binding agreement between you (and, if you use the Service on behalf of an organization, that organization — collectively "you", "Customer") and HarnessHive, operated by HarnessHive ApS, a Danish company (CVR 46812549), Ræveskovsvej 20, 2820 Gentofte, Denmark ("HarnessHive", "we", "us", "our").

They govern your access to and use of the HarnessHive cloud-based wiring harness design platform, our website, and related services, including AI features, integrations, and API access (the "Service"). By creating an account, subscribing, or using the Service, you agree to these Terms. If you do not agree, do not use the Service.

If you accept these Terms on behalf of an organization, you represent that you are authorized to bind that organization.

2. The Service

HarnessHive provides an online platform for designing, storing, and managing wiring harness designs and related projects. We may add, change, or discontinue features over time. We will give reasonable notice of material changes that adversely affect your use of the Service.

Beta and early access. HarnessHive is a young product. Features marked as beta or early access, and any free beta access, may be incomplete, change, or be withdrawn, and are provided without any commitment to availability. We will give reasonable notice before ending free beta access.

3. Accounts and eligibility

You must provide accurate registration information and keep it up to date. You are responsible for safeguarding your login credentials and for all activity under your account. Notify us promptly at info@harnesshive.com of any unauthorized use. You must be at least 18 years old and able to form a binding contract to use the Service, and you confirm this when you create an account. The Service is intended for business/professional use. If you use it as a consumer, the mandatory consumer protection law of your country applies, and nothing in these Terms limits those rights.

API access and credentials. The Service may let you create API tokens or other credentials that give external tools, such as AI assistants or your own software, access to your workspace. You are responsible for keeping them secret, for the tools you connect, and for all actions taken with them, including changes made without approval of each change where you granted write access. Revoke credentials you no longer use or that may have been exposed.

4. Subscriptions, plans, and free trial

4.1 Plans. The Service is offered on subscription plans billed monthly or annually, and priced per seat (per user) unless stated otherwise at purchase. The features, prices and limits of each plan are shown on our pricing page and at checkout. The price shown at checkout when you subscribe is the price that applies to you, subject to Section 5.3.

4.2 Seats. Per-seat plans entitle the number of named users you purchase. You are responsible for your users' compliance with these Terms.

4.3 Free trial. We may offer a limited free trial. Trials are provided "as is" and may be modified or withdrawn at any time. Unless you cancel before the trial ends, your subscription may convert to a paid plan and billing will begin, as disclosed at signup. Any data or configurations from a trial may be deleted if you do not subscribe, after the 90 day period described in Section 13.

4.4 Paid features and usage limits. Some features, such as AI features, integrations, and API access, may only be available on certain plans. Features may be subject to usage limits, such as daily limits, which we may adjust.

5. Payment, renewal, and cancellation

5.1 Merchant of record. Payments are processed by our merchant of record, Polar (polar.sh), which acts as the seller of record and handles payment processing and applicable taxes (VAT/sales tax). Your purchase is also subject to Polar's terms. We do not store your full payment card details.

5.2 Billing and auto-renewal. Subscriptions renew automatically at the end of each billing period (monthly or annually) at the then-current price, unless you cancel before renewal. By subscribing, you authorize recurring charges through Polar.

5.3 Price changes. We may change prices. For changes affecting your plan, we will give reasonable prior notice (at least 30 days), and the new price applies from your next renewal.

5.4 Cancellation. You may cancel at any time, effective at the end of your current billing period. After cancellation you retain access until the period ends.

5.5 No refunds. Except where required by law (including Section 5.6), payments are non-refundable and we do not provide refunds or credits for partial periods, unused seats, or unused time.

5.6 Consumer withdrawal rights (EU). If you are a consumer in the EU, you have a statutory right of withdrawal of 14 days from the start of your subscription. Where you request that we begin providing the Service before the withdrawal period ends, you acknowledge that you may lose that right once the Service has been fully performed, or must pay for the part already provided, in accordance with applicable law. To withdraw, contact us at info@harnesshive.com.

5.7 Non-payment. If a payment fails or is overdue, we may suspend or terminate access after reasonable notice.

6. Your content and intellectual property

6.1 Your content. "Customer Content" means the designs, projects, files, and data you create, upload, or store in the Service, including your inputs to and output from AI features. As between you and us, you own all rights in your Customer Content. We claim no ownership of it.

6.2 License to us. You grant us a limited, worldwide, non-exclusive license to host, store, process, transmit, display, and back up your Customer Content solely to provide, secure, and support the Service for you, and as instructed by you, including sending it to AI providers when you use AI features and to third parties when you use integrations. This license ends when you delete the content or your account, subject to reasonable backup retention and legal requirements. Our handling of any personal data within Customer Content is governed by our Privacy Policy and, where applicable, a data processing agreement.

6.3 Aggregated/anonymized data. We may generate and use aggregated and/or anonymized data derived from use of the Service — data that does not identify you, your users, or any individual, and does not reveal your confidential designs — to operate, analyze, and improve the Service, including current and planned features. We do not use your Customer Content to train AI models without your consent (see Section 6.6). Under their terms, our AI providers do not train their own models on your Customer Content.

6.4 Our IP. The Service, including its software, design, and trademarks, is owned by us or our licensors and protected by law. We grant you a limited, non-exclusive, non-transferable, revocable right to use the Service during your subscription or free access, subject to these Terms. You get no rights except those expressly granted.

6.5 Feedback. If you give us feedback or suggestions, we may use them without restriction or obligation to you.

6.6 AI improvement. We may in future offer a setting that lets workspace admins allow us to use AI inputs and outputs from their workspace, such as prompts, conversations, and accepted or rejected suggestions, to train and improve our AI features. This is not active today. When available, it will be off unless an admin turns it on, and an admin can turn it off at any time. Data used this way will not be used to train our AI providers' models, and we will take measures so that our AI features do not reveal one customer's designs to another.

7. AI features

7.1 What they do. The Service includes features that use artificial intelligence, for example to answer questions about your designs, propose changes, or generate parts of a design ("AI features"). They are powered by third party AI providers, which are listed in our Privacy Policy and on our subprocessors page.

7.2 You stay in control. Where an AI feature proposes changes in the editor, nothing is applied to your design until a user approves it, and applied changes are recorded and can be undone like any other edit. Changes made through API access with write permission may apply immediately (see Section 3).

7.3 Check the output. AI output can be incomplete or wrong, even when it looks plausible. You are responsible for reviewing and verifying any output before you rely on it or use it in a design. You remain the engineer of record, and Section 10 applies to AI output in full.

7.4 Acceptable use. You must also follow the usage policies of our AI providers when using AI features, and you may not use it to try to extract data you are not allowed to access or to work around usage limits.

8. Acceptable use

You agree not to: (a) use the Service unlawfully or in violation of third-party rights; (b) upload content you lack the rights to, or that is unlawful, infringing, or malicious; (c) attempt to gain unauthorized access to, disrupt, or reverse engineer the Service (except as permitted by law); (d) resell, sublicense, or provide the Service to third parties except your authorized users; (e) exceed your plan's seats or limits, or circumvent usage controls; (f) use the Service to build a competing product; or (g) store or process in the Service any technical data controlled under export control rules, such as ITAR, the EAR or the EU dual use regulation, unless we have agreed to this in writing, or use the Service in breach of applicable export control or sanctions laws, including from a sanctioned country or as a sanctioned person. You are responsible for classifying your own designs under these rules. We may suspend accounts that breach this section.

9. Third-party services

The Service relies on third-party providers as described in our Privacy Policy and listed on our subprocessors page. We are not responsible for third-party services, and their terms may also apply to you.

Integrations. The Service may let you connect accounts, tools, or data from third parties, such as CAD, PLM, or AI tools ("Integrations"). When you enable an Integration, you authorize us to access, import, and exchange data with that third party on your behalf as needed for the Integration. Your use of the third party is governed by your agreement with it, and we are not responsible for its service or how it handles your data. Integrations depend on the third party and may change or stop working if it changes its service.

10. Availability, warranties, and disclaimers

We aim to keep the Service available and reliable but do not currently commit to a specific uptime service level unless separately agreed in writing. The Service (including beta features and AI output) is provided "as is" and "as available." To the maximum extent permitted by law, we disclaim all implied warranties, including merchantability, fitness for a particular purpose, and non-infringement. You are responsible for verifying that any design output meets your engineering, safety, and regulatory requirements — the Service is a tool and does not replace professional review. You are also responsible for keeping your own copies of designs that are important to you.

11. Limitation of liability

To the maximum extent permitted by law: (a) we are not liable for indirect, incidental, special, consequential, or punitive damages, or for lost profits, revenue, data, or goodwill; and (b) our total aggregate liability arising out of or relating to the Service and these Terms will not exceed the greater of EUR 100 and the amounts you paid to us for the Service in the twelve (12) months before the event giving rise to the claim. Nothing in these Terms limits liability that cannot be limited under applicable law (such as for gross negligence, willful misconduct, or death/personal injury), or your rights as a consumer under mandatory law.

12. Indemnification

If you use the Service as a business, you will defend and indemnify us against third-party claims arising from your Customer Content, your use of the Service in breach of these Terms, or your violation of law or third-party rights, to the extent permitted by applicable law.

13. Term, suspension, and termination

These Terms apply while you use the Service. You may stop using and cancel at any time (Section 5.4), and you can delete your account at any time. Deleting your account permanently deletes your Customer Content and cannot be undone. We may suspend or terminate your access if you materially breach these Terms, fail to pay, or if required by law, generally with reasonable notice where practicable. On termination or when your subscription or trial ends, your right to use the Service ends. We will make your Customer Content available for export for 90 days after that, after which we will delete it, subject to our Privacy Policy and legal obligations.

14. Changes to these Terms

We may update these Terms from time to time. For material changes we will provide reasonable notice (for example, by email or in-product notice, at least 30 days before they take effect) and update the "last updated" date. Continued use after changes take effect constitutes acceptance. If you do not agree, you should stop using the Service and may cancel before the changes take effect.

15. Governing law and disputes

These Terms are governed by the laws of Denmark, without regard to conflict-of-laws rules, and the courts of Denmark will have jurisdiction, unless mandatory consumer-protection law in your country of residence provides otherwise. Consumers can also complain to the Danish Consumer Complaints Board (Forbrugerklagenævnet).

16. General

These Terms, together with our Privacy Policy, Cookie Policy and any order or plan details, form the entire agreement between you and us regarding the Service. Some features may come with additional terms that we show when you enable or buy them. Those terms apply in addition to these Terms and prevail for that feature where they conflict. If you have signed a separate written agreement with us for the Service, that agreement prevails over these Terms where they conflict. If any provision is held unenforceable, the rest remains in effect. Our failure to enforce a provision is not a waiver. You may not assign these Terms without our consent; we may assign them in connection with a merger, acquisition, or sale of assets.
