Legal

Terms of use

The agreement between you and the provider of KaufWach. Read section 6 in particular: it sets out what AI-generated output is, and what it is not.

Last updated: August 9, 2026

Scope

These terms govern your use of the KaufWach web application and everything it produces. By creating an account or using the service you accept them. Deviating terms of your own apply only where we have agreed to them in writing.

The service is aimed at businesses and at consumers buying property in Germany. Where you act as a consumer, mandatory statutory rights apply in addition to these terms and are not restricted by them.

Access and accounts

Access is currently by invitation.

  • You must give accurate registration details and keep them current.
  • Credentials are personal. Keep them secret and tell us at once if you suspect misuse.
  • You are responsible for everything done under your account, including by members you invite into your workspace.
  • You must be at least 18 years old and have legal capacity to enter into contracts.

Acceptable use

You may use KaufWach to analyse property listings and documents you are entitled to process. You may not:

  • Upload content you have no right to use, or personal data of third parties without a legal basis.
  • Circumvent access controls, rate limits or tenant isolation, or probe the service for vulnerabilities without our written permission.
  • Scrape the service by automated means, resell access, or use the output to build a competing product.
  • Upload malware, or content that is unlawful, defamatory or infringing.

Portal links and third-party documents

When you paste a listing URL we retrieve that page in order to read it. You are responsible for having the right to import that content and for observing the terms of the portal it comes from. Portals may block automated retrieval, and we cannot guarantee that any given link can be imported.

Documents supplied by an agent or a seller usually carry third-party copyright. Uploading them to evaluate the property yourself is normally covered by the purpose for which you received them; passing the resulting reports on to others is not automatically covered.

Your content

Your documents, answers and the analyses derived from them remain yours. You grant us only the rights needed to run the service: to store, process, display and transmit that content to the processors described in the privacy notice, for as long as your account exists.

We do not use your content to train AI models and we do not disclose it to other customers. You can delete a property or your entire account, which removes the associated content as set out in the privacy notice.

AI-generated output — no warranty of correctness

This section restates, in contractual terms, the warning at the top of this page.

The service extracts, calculates and summarises using AI models. Its output is a machine-generated estimate, not a verified statement of fact, and it may be incomplete, outdated or simply wrong.

  • We give no guarantee and no warranty, express or implied, as to the accuracy, completeness, currency or fitness for a particular purpose of any extracted value, score, cost estimate, risk or generated text.
  • Confidence scores are the model's own estimate of its reliability. A high score is not a confirmation, and a low score is not a defect.
  • Cost and renovation figures are ranges derived from general reference data. They are not quotations, valuations or appraisals.
  • Before relying on any figure, verify it against the linked source document. Where the analysis and the document disagree, the document governs.
  • To the extent legally permissible we exclude liability for decisions taken on the basis of the output; section 11 sets out the limits that apply in every case.

No professional advice

KaufWach is a software tool, not a Rechtsanwalt, Steuerberater, Sachverständiger, Energieberater or Immobiliengutachter. Nothing the service produces constitutes legal, tax, financial, energy or structural advice, and no such professional relationship arises from using it. References to statutory duties, for instance under the GEG, are informational and can be out of date or inapplicable to your case.

Availability and changes

The service is under active development and is provided without guaranteed availability. Features may change or be withdrawn, and maintenance windows or third-party outages can interrupt access. We give reasonable notice of changes that materially reduce functionality you rely on.

Fees

Access during the invite-only phase is free of charge unless we have agreed otherwise with you in writing. If paid plans are introduced, prices and payment terms will be presented before you accept them. No charge is ever made without that separate agreement.

Term and termination

You can close your account at any time. We may suspend or terminate access with reasonable notice, or immediately where there is a serious breach of these terms, a legal obligation, or a risk to the service or to other users. On termination your content is deleted as described in the privacy notice, so export what you need beforehand.

Liability

We are liable without limitation for intent and gross negligence, for injury to life, body or health, under the Produkthaftungsgesetz, and wherever we have given a guarantee.

  • For slight negligence we are liable only for breach of a material contractual obligation — a duty whose fulfilment makes proper performance possible and on whose observance you may regularly rely — and then only for foreseeable damage typical of this kind of contract.
  • Any further liability for slight negligence is excluded, in particular for lost profit, missed opportunities, and losses arising from a purchase decision taken on the basis of an analysis.
  • Because the output is generated and unverified, damage caused by relying on it without checking the source document is not foreseeable damage typical of this contract.
  • You are responsible for keeping your own copies of the documents you upload. We are not a document archive.

Changes to these terms

We may amend these terms where the product, the law or the technical landscape changes. You will be notified at least 30 days before an amendment takes effect, and continued use after that date counts as acceptance. If you do not accept, you may close your account before that date at no cost.

Governing law and venue

German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. If you are a consumer resident in the EU, this does not deprive you of the protection of mandatory provisions of the law of your country of residence.

Where you are a merchant, a legal entity under public law or a special fund under public law, the exclusive place of jurisdiction is the registered seat of the provider.
