Privacy policy

Updated: 29 September 2026

1. Data controller

The controller responsible for processing personal data on this website is:

Simeon Krell Immobilien, sole proprietor Simeon Krell

Phone: 0176 70332946
Email: simeon@krellimmobilien.de

2. Hosting and technical operation

This website is hosted as a ChatGPT Site by OpenAI. When it is accessed, the hosting provider processes technical connection data needed to deliver, maintain and secure the website. This may include your IP address, date and time, requested address, browser and operating system details, referrer information and security data.

We use OpenAI as a processor to operate this website. Its runtime and database use Cloudflare services. OpenAI may also use the companies on its current subprocessor list for hosting, infrastructure, delivery and support. Processing is subject to the terms and data processing addendum for ChatGPT Sites.

OpenAI states that regional data residency is not currently provided for ChatGPT Sites. Processing outside the European Economic Area therefore cannot be ruled out. Required international transfers are subject to the transfer mechanisms and safeguards described in the data processing addendum.

Technical connection data is processed to provide the website safely and reliably. The legal basis is Article 6(1)(f) GDPR. Under the hosting service terms, the data is processed for as long as necessary for operation, security and troubleshooting. The hosting provider does not publish a fixed, project-specific retention period for technical logs from this individual website.

3. Saving privacy settings

To remember your choice in the privacy dialog, we save it in your browser's local storage. It records whether you accepted or declined visit statistics and broad interaction statistics. The choice is stored for 180 days and is requested again afterwards. This setting lets us respect your choice without asking on every page view. You can change it at any time using “Privacy settings” at the bottom of the website.

4. Optional visit and interaction statistics

Statistics are enabled only if you expressly agree in the privacy dialog. For visit statistics, the browser creates a random identifier and stores it locally for up to 30 days. This lets us count repeat visits from the same browser during that period. The identifier does not contain your name or contact details and is not used for advertising profiles; it may nevertheless be personal data.

If you separately agree to broad interaction statistics, we also count scroll milestones at 25, 50, 75 and 100 percent, and clicks on selected links to contact, property valuation and listings. We store the page path, event time, type of statistics event and, where relevant, its broad category. The statistics feature does not store IP addresses. We do not capture mouse movements, session recordings, form entries or advertising profiles. Statistics are stored in the website database. Before a new statistics entry is saved, the website deletes entries older than 30 days. If no further statistics entry is made, this cleanup is not triggered.

The legal basis is your consent under Article 6(1)(a) GDPR and, where information is stored on or read from your device, section 25(1) TDDDG. If you decline or later withdraw consent, no further statistics are collected. Existing statistics entries are deleted through the cleanup process described above. You can change your choice at any time using “Privacy settings”; we ask again after 180 days.

5. Local asking price comparison

When you use the comparison feature on the “Property assessment” page, your browser sends selected property details to our website API: property type, postal code, living area, year built and condition. We process these details only to determine a relevant asking price range and return the result to your browser. Your name, email address and phone number are not sent to this API. The comparison feature does not store the entries in the application database. The hosting provider may process technical connection data about this request as part of website operation.

We process the details you enter for the requested comparison to provide this feature and take steps you request (Article 6(1)(b) GDPR); where this basis does not apply, we rely on our legitimate interest in providing a useful, functional website (Article 6(1)(f) GDPR). Displayed figures are based on asking prices and are not a market valuation.

6. Valuation requests and contact

The details you enter in the valuation request or contact form are first processed in your browser. The website does not send these form entries to a server or store them in its application database. If you choose “Open email application”, the details are placed in an email draft in the application you selected. They are sent to us only after you send the message there. The email services you use also process the message under their own privacy policies. You can also call us.

If you send us an enquiry or call us, we process the contact details and property information you provide to reply, handle your request and, where relevant, prepare pre-contractual steps. The legal basis is Article 6(1)(b) GDPR if your enquiry concerns a contract or pre-contractual steps; otherwise, we rely on Article 6(1)(f) GDPR to handle your request. We delete the information once the enquiry is complete and no legal retention duty or other legitimate reason for continued storage applies.

7. Propstack property listings and external content

When you visit the “Properties” page, our server requests only properties from Propstack that have explicitly been marked “Website freigegeben” in Propstack and marked there as publicly marketable. The connection is server-side. Your name, contact details and form entries are not sent to Propstack; the API key remains on the server. We use only approved listing information from Propstack, such as the title, location, price, areas, room count, description and public property photos. Owner details, internal notes and non-public images are not displayed on the website.

We use Propstack as our CRM provider to technically display and maintain property listings that we have been instructed to market. Propstack processes technical connection data generated by server requests. The legal basis is our legitimate interest in marketing properties under an instruction (Article 6(1)(f) GDPR) or performing the brokerage instruction (Article 6(1)(b) GDPR). Property photos are loaded directly by the website from image storage used by Propstack. The image service therefore receives the connection data required from your browser, in particular your IP address, the time and the requested image address. The website does not load external analytics or advertising services.

8. Your data protection rights

Subject to legal requirements, you have the right to access, rectification, erasure, restriction of processing and data portability. Where we process data on the basis of legitimate interests, you may object for reasons relating to your particular situation. You may withdraw consent at any time with effect for the future. Withdrawal does not affect the lawfulness of processing before it.

To exercise your rights, write to simeon@krellimmobilien.de.

You may also lodge a complaint with a data protection supervisory authority. The authority for Rhineland-Palatinate is:
