Terms of Service

Last updated: 20 July 2026

1. Who we are

HYWOS is a product of TROLUT UG (haftungsbeschränkt), Rosa-Luxemburg-Ring 10 B, 34253 Lohfelden, Germany (“we”, “us”). These terms govern your use of the HYWOS website, account system and desktop software (“the Service”). Full company details are in our Impressum.

2. Accounts

You must provide accurate details when registering and keep your login credentials secure. You are responsible for activity under your account and must be at least 18 years old or a business. Notify us promptly if you suspect unauthorised use.

3. Plans and payment

• Free — evaluation use in time-boxed sessions (currently one hour per session), on your own machine.
• Monthly — a recurring subscription billed monthly (currently €39/month) for the full local assistant.
• Custom — company deployments (white-label, multiple seats, onboarding) arranged individually.

Current prices and features are shown on the pricing page and may change with reasonable notice; changes never affect a period already paid for. Subscriptions renew automatically at the then-current price until cancelled. Payments are handled by Stripe.

4. Licence and single computer

While your plan is active, we grant you a non-exclusive, non-transferable licence to use HYWOS for your own engineering work. Unless your plan says otherwise, each licence is for a single user and is bound to a single computer; to move it to another machine, contact {email}. You may not resell, sublicense, redistribute, or reverse-engineer the software except where the law or an open-source component licence expressly permits it.

5. The software runs locally

HYWOS runs on your machine and processes your documents locally; the AI model also runs locally. You are responsible for your data and for keeping your own backups. Activation and periodic licence checks (for example monthly) require an internet connection; between checks the app can keep working offline until your plan expires.

6. Acceptable use

You agree not to use the Service unlawfully, to infringe others' rights, or to disrupt or circumvent its technical protections or licensing. You remain responsible for reviewing any output before relying on it for engineering, safety or compliance decisions.

7. Cancellation and right of withdrawal

You may cancel a subscription at any time; access then continues until the end of the current paid period, and it is not renewed. Consumers in the EU additionally have a statutory 14-day right of withdrawal for the initial purchase. Where you ask us to begin providing a paid digital service during the withdrawal period, you acknowledge that the right of withdrawal lapses once the service has been fully provided. To cancel or withdraw, use your account or email {email}.

8. Availability and changes

We aim for a reliable service but do not guarantee uninterrupted availability; maintenance and updates may cause temporary interruptions. We may modify or discontinue features, giving reasonable notice of material changes that affect you.

9. Warranty and liability

The Service is provided with reasonable care but otherwise “as is”. We are liable without limitation for damages arising from injury to life, body or health, and where liability is mandatory (e.g. under the Product Liability Act) or caused by intent or gross negligence. For slight negligence we are liable only for breach of an essential contractual obligation (a duty whose fulfilment makes proper performance possible and on which you may rely), and then limited to the foreseeable, contract-typical damage. Any further liability is excluded.

10. Governing law and jurisdiction

These terms are governed by the laws of Germany, excluding the UN Convention on Contracts for the International Sale of Goods, and subject to the mandatory consumer-protection rules of your country of residence. Where you are a merchant, the place of jurisdiction is Kassel, Germany.
