AI Transparency Notice

1. Overview

We use artificial intelligence (AI) in two features: property valuation and reading loan documents. Both run only when you initiate them. Their results are for your information; neither feature makes a decision about you. We do not use AI to assess people, build profiles, monitor your content, or decide on your access to the platform, your contracts or your price.

The AI providers are OpenAI and Google. They process the data as our processors and, under their contractual terms, do not use it to train their models. The processing entity, the place of processing and the safeguard for transfers to third countries are set out in the Recipients and Subprocessors register. The legal bases and your rights under the GDPR are described in our Privacy Policy.

2. Property Valuation

What the feature does. When you request it, the AI researches published market data and current comparable listings, determines for let residential property an indicative value for the rent permitted on a new letting, and from this estimates the value of your property. The indicative rent is a guide drawn from published sources; we carry out no legal review of the rent permitted in the individual case. If you complete the assistant up to the result when you register, we produce a shortened valuation once; it relies only on the property details you enter in the assistant.

Provider. OpenAI performs every step.

Data transmitted. The valuation receives your property record: address and coordinates, property, building and energy characteristics, purchase, rent, cost and service-charge data, earlier valuations by persons or institutions, listing data, your free-text entries on the property, and photos from the gallery, reduced in size and without embedded metadata. Rent data is transmitted without the names or contact details of tenants. Data about your contacts, loan data, your name, your contact details, your organisation and uploaded documents are not transmitted.

Web search. For the research, OpenAI uses a web search; the search queries reach a search provider through OpenAI, which processes them under its own responsibility (Recipients and Subprocessors register). They describe the property only in general market terms such as town, district, property type and size. Only for the indicative rent does the search also receive street, house number and postcode, because the rent index assigns the residential location class by address.

Result. The AI returns an estimated value with a value range, a confidence score, its reasoning and the comparables it relied on. The valuation is stored with your property and, like any other valuation, can feed in as the current value into your portfolio, your equity and the ratio of loan balance to property value.

3. Reading Loan Documents

What the feature does. You select uploaded PDF documents relating to a loan and have their values, such as the loan amount, interest rate, instalment and repayment schedule, read into the loan form.

Provider. Google (Gemini API) reads the documents. OpenAI receives the same documents if the reading by Google fails or if a second reading is to resolve contradictory values.

Data transmitted. The selected documents are transmitted in full and unaltered, with everything printed in them: including names, addresses and bank details of borrowers, guarantors or other persons and, where present, special categories of personal data such as a health declaration. Please therefore select only documents that concern the loan. You are responsible for the transmission of other persons' data contained in these documents. No document is transmitted unless you select it and start the reading.

Result. The values read appear in the loan form. You check and confirm each value; only the loan you save is stored. We do not store the result of the reading itself. The reading is an input aid. It assesses neither the loan nor anyone's creditworthiness; we do not broker loans and do not advise on them.

4. Storage and Your Control

We store a valuation with your property together with its data basis and the sources of the researched figures, so that you can trace the result; it is deleted with the property. For reuse in later valuations we also keep an indicative rent separately for up to 90 days and the description of a photo at most until the photo is deleted; as part of a valuation's data basis, both remain stored with that valuation. If you request a valuation again within 90 days with unchanged data, we refer you to the existing valuation; you can expressly request a new run.

You decide whether to request a valuation and whether to rely on it. An AI valuation cannot be edited, but you can record your own valuations. If the property data is incorrect, correct it and request a new valuation. If you consider a valuation wrong, write to us at support@dein-eigentum.de; we will review it and reject it where appropriate. A rejected valuation no longer feeds into the property value, your equity or the ratio of loan balance to property value. On request we delete a rejected valuation and explain the methodology used.

5. Storage by the Providers

At our instruction, OpenAI does not store requests and responses for later retrieval, but keeps logs for up to 30 days to detect abuse, unless the law requires longer retention. Google logs requests and responses for a limited period, solely to detect violations of its usage policies and for disclosures required by law.

6. What Does Not Belong in Free Text

The free-text fields of a property and the documents you select reach the provider without our checking them first. Please do not enter health data or other special categories of personal data (Art. 9 GDPR) or data relating to criminal convictions (Art. 10 GDPR) in free-text fields; a valuation does not need them.

7. Limits of the Results

An AI valuation is an estimate based on your data and published market information. It is not an expert opinion, in particular not a market value determination under Section 194 of the German Building Code (BauGB) or under the German Property Valuation Ordinance (ImmoWertV), not a determination of the mortgage lending value, not a valuation for tax purposes under the German Valuation Act (Bewertungsgesetz) and not evidence before courts, authorities, notaries or banks; nor is it advice on buying, selling, letting, financing, investment, law or tax. Circumstances not recorded in the platform, such as the interior condition, defects, encumbrances and the circumstances of the individual transaction, are not taken into account. It can differ considerably from the price actually achievable. AI results can be wrong even when they are phrased convincingly, and values read from documents can be misread. Check every result before you rely on it, and obtain a valuation by a qualified expert for important decisions. Providing an AI result does not create an advisory or information contract, and we give no guarantee of its accuracy or completeness. Our liability is governed by our Terms of Service.

8. AI Act

We integrate AI models from OpenAI and Google into our own features. None of the features is a prohibited practice or a high-risk AI system within the meaning of Regulation (EU) 2024/1689. In your account we label AI valuations as AI generated.

9. Changes

The effective date shows the version of this notice. If the AI features, their providers, the model family behind a feature or the data transmitted change, we update this notice and inform you as described in the Privacy Policy. Earlier versions are available on request.
