Terms of Service

Last updated: 5 October 2026

These terms govern the use of Lyxter, the AI diagnostic assistant at app.lyxter.ai, provided by Lyxter ApS (CVR 46627571), Bjergegade 58, 6870 Ølgod, Denmark ("we", "us"). By creating a company account or using the service, you agree to these terms on behalf of your company.

1. The service

Lyxter provides AI-generated diagnostic and repair guidance for vehicles and machinery of every kind (heavy vehicles, agricultural and construction machinery, cars and vans) and for workshop equipment, based on fault codes, symptoms, screenshots, and questions you submit. The service works alongside your existing diagnostic tools; it does not replace them.

2. Professional judgment and safety

Never rely on Lyxter alone for safety-critical decisions (brakes, steering, load handling, or any situation where failure could cause injury).

3. Accounts and seats

• A company account is created by its owner, who can invite team members up to the number of seats on the account. A company that has bought no seats of its own - a free or invoiced account - can invite up to the limit that applies to it instead. Either way the limit is shown under Settings, Team before it refuses an invitation.
• You are responsible for keeping login credentials confidential and for all activity under your company's accounts.
• Accounts are for your company's internal use; do not resell or share access outside your company.

4. Payment

• Unless your company is on an arrangement agreed with us (below), Lyxter is a paid subscription, billed per seat through Stripe: per month or, where the billing page offers yearly billing, per year in advance. Where it is offered, a plan's yearly price is at least 15% lower than twelve months at its monthly price. Prices are shown at checkout; VAT is applied according to EU rules.
• Subscriptions renew automatically until cancelled. You can change seats or cancel any time in the billing portal; cancellation takes effect at the end of the paid period.
• Enterprise and other agreed accounts are arranged separately: the price, the number of seats and the monthly allowance - of diagnostics or of messages, as your offer states - are the ones agreed with you and set by Lyxter. The written offer we send you is accepted from the link on it (or by writing to us), by a person with authority to accept it on behalf of your company, and is paid in the way chosen when it is accepted: by card, which starts a subscription charged automatically at the agreed rate; by invoice, which starts a subscription invoiced at the agreed rate each period and due within the payment terms stated on the offer; or, for a public institution, by e-invoice to its EAN number. A card or invoiced subscription renews automatically at the agreed rate until it is ended. Seats, the allowance and the end of the agreement are changed by agreement with us - write to hello@lyxter.ai - as is anything the billing portal does not offer your account.
• Diagnostics: a plan can include a monthly allowance of diagnostics. It is a number per seat, pooled across your company, so the allowance is the company's as a whole and anyone in it can use it. The billing page shows whether your company has one and, if so, how much of it has been used and the date it resets. It resets every month: on your subscription's billing day, also when you pay yearly, or with the calendar month where your company has no subscription of its own. Unused diagnostics do not carry over.
• What counts as a diagnostic: a chat in which Lyxter answers a fault on a vehicle or machine (explaining a fault code included), or in which it searches your company's manuals or the web. A chat is counted once, at that point, however long it runs: follow-up questions in the same chat are free. A chat that only records finished work, asks about the app, or looks something up without such a search is not counted. A new chat about the same fault is a new diagnostic. Deleting a chat does not give a diagnostic back. Where the billing page lists the chats that were counted, your company's owner can mark one that was counted wrongly, a limited number of times in each period (the page states how many), and it is given back at once.
• When the allowance is used: once your company has used its allowance for the period, Lyxter may decline to start a new diagnostic until the allowance resets, or until it is raised by adding seats or moving to a larger plan. A chat in which Lyxter has already answered a fault is not cut off, and recording work, questions about the app and other use that is not a new fault stay available. To tell a new fault from the rest, a message that would start one may be checked automatically (see the Privacy Policy, section 2); if that check cannot be made, the message is answered. Because a diagnostic is counted when it is answered, a period's count can end slightly above the allowance; nothing extra is charged for that.
• Vehicles: Fleet and Service are part of every plan. A plan can limit how many vehicles your company's Fleet holds. Where it does, every machine in Fleet counts - your company's own and your customers' alike - and the app states the limit when it is reached. The limit only stops more vehicles from being added: the ones already there stay, with everything recorded on them, and are never hidden, locked or deleted because of it.
• Fair use: separately from any diagnostics allowance, your company has a monthly message allowance, shown on the billing page as Messages included; on a subscription bought in the app it is a per-seat quota.

5. Your content and the shared knowledge base

• Your chats stay private to your company. Lyxter staff can view them when needed for support, quality assurance, and safety review; staff access is read-only and every access is logged (see the Privacy Policy).
• To improve the service for all customers, Lyxter learns structured knowledge only from chats: fault codes, AI-written fix summaries and technical lessons, and anonymous counts of whether a fix worked - never your own text, your images, or anything identifying your company. Each fix summary and technical lesson learned from a chat is automatically scrubbed by our software for identifying details (emails, phone numbers, number plates, and identification numbers) before it is stored. What Lyxter learns from your chat is used in your own company's diagnoses at once, but reaches other companies only after Lyxter staff review and approve it, or when it restates knowledge Lyxter had already approved. The AI model itself is never trained on your data. See the Privacy Policy.
• Your company's owner can switch this sharing off in Settings, under Company, and Lyxter staff can set it for you. From then on nothing learned from your company's chats, and none of its reports on whether a fix worked, reaches other companies; your own company's AI keeps learning from them. What was shared before stays shared, and manuals you upload are not covered by this setting.
• To test the AI before changes go live, we may derive an internal test scenario from a real case after removing all identifying details (names, companies, contact details, number plates); the cleaned version is reviewed by staff first, and images are never included.
• Company owners and the admins they appoint may upload manuals to the company's Manuals, and any team member may upload a manual to a vehicle's own page. Team members may also save manual-like content shared in a chat (pasted manual text, photographed manual pages, or an attached PDF file) to the company's Manuals, but only by confirming the save prompt the app shows - nothing is saved from chat without that explicit confirmation, and a saved item follows the same rules as an uploaded manual. Uploaded manuals stay private to your company: once its pages have been read, the AI uses a manual in your company's own chats, before Lyxter has reviewed it. Only your company's owner can share a document with other companies, and only after saying who wrote it. By sharing a document, the owner confirms that your company may lawfully share it - because it is your company's own work, because its maker publishes it for anyone to share, or under a licence that allows it - and that it holds no personal data about your customers, your staff or anyone else. A document whose author you do not know cannot be shared. A shared document reaches other companies only after Lyxter has reviewed and approved it; the AI in other companies' chats then reads its text, no other company can open or search the file, and your owner can stop sharing it at any time. When a shared document reaches other companies, Lyxter may add a small number of short, AI-written technical lessons distilled from it to the shared knowledge base; each lesson is reviewed first, is written in the AI's own words rather than copied from the document, is automatically scrubbed by our software for identifying details before it is stored, and contains nothing identifying your company. Lessons already written stay if the document stops being shared. Lyxter staff never share a document for your company. We may reject or remove any upload, or take a shared document back out of the shared knowledge base, and you may delete your company's uploads at any time.
• If you enter personal data about someone else - for example a customer's name and contact details, whether under Customers or when documenting a service for one of them - your company remains responsible for that data and for having the right to enter it. Lyxter only stores and processes it on your instructions (see the Privacy Policy).

6. Acceptable use

Do not misuse the service: no attempts to breach security, access other companies' data, overload the systems, extract the underlying models or prompts, or use the service for anything unlawful. We may suspend accounts that do.

7. Availability and changes

We aim for high availability but do not guarantee uninterrupted service. We may improve or change features over time. If we discontinue the service, we will give reasonable notice and you can export your data.

8. Liability

To the maximum extent permitted by law, our total liability for any claims arising out of the service is limited to the amount your company paid to us in the 12 months before the claim. We are not liable for indirect damages, lost profits, vehicle downtime, or the outcome of repairs (see section 2). Nothing in these terms limits liability that cannot be limited under Danish law.

9. Termination and data deletion

You can stop using the service and cancel at any time. Any user can delete their own account from inside the app (Settings, You, Delete account) or on the public account deletion page, which works without the app installed: their sign-in and personal data are deleted, while the records they wrote for their company stay with the company, without their name. The company owner can delete the whole company account the same way - every user account in it, chats, vehicles, service history, uploaded manuals, customer records, documents and the Stripe customer - except billing records we must keep under bookkeeping law, knowledge-base entries that no longer identify anyone, and a minimal record that the deletion took place, kept so it can be accounted for afterwards (Privacy Policy, sections 4 and 7). Because there is one owner per company and ownership cannot be transferred, the owner deleting their own account deletes the company account, and the app says so before they confirm.

A deletion is confirmed by typing the name of what is being deleted, scheduled for 7 days later and carried out automatically on that day; it can be withdrawn until then and cannot be undone afterwards. In every case it is completed within 30 days. Nobody has to contact us to complete it. If you can no longer log in, write to hello@lyxter.ai from the address on your account.

10. Governing law

These terms are governed by Danish law. Disputes are settled by the Danish courts, with the City Court of Copenhagen as first instance, unless mandatory law provides otherwise.

11. Changes to these terms

We may update these terms as the service evolves. Significant changes will be announced to company owners by email at least 30 days before they take effect.
