2. Website visits and hosting

This website is provided using OpenAI Sites through the technical infrastructure of OpenAI and Cloudflare. Visits involve processing data such as the IP address, time of access, requested page, browser and device information, and technical connection data. This enables content delivery, error analysis and protection against misuse.

The legal basis for providing this information website is Article 6(1)(f) GDPR. The legitimate interest is the reliable and secure operation of the website. Recipients of technical access data are the hosting platform and its relevant technical service providers.

For individuals in the EEA, OpenAI identifies OpenAI Ireland Limited, 1st Floor, The Liffey Trust Centre, 117–126 Sheriff Street Upper, Dublin 1, D01 YC43, Ireland, as the controller for the processing described in its privacy policy. Further information, including retention and privacy contact details: OpenAI EU privacy policy.

Cloudflare, Inc., 101 Townsend St., San Francisco, CA 94107, USA, provides technical infrastructure. Information about processing is available in the Cloudflare privacy policy.

Platform providers may process data outside the EEA, particularly in the USA. Their privacy policies explain the transfer mechanisms used, such as adequacy decisions or EU standard contractual clauses, and how to obtain information about safeguards. The specific retention period for technical platform logs depends on the purposes and retention criteria described there. SchadstoffCheck does not set a separate fixed deletion period for these platform logs.

3. Preparing a project enquiry

The enquiry form initially processes your entries locally in your browser. These may include your name, email address, phone number, building type, year of construction, location, timeframe and project description. Name, email address and phone number are optional; the location and description are required for the summary.

When creating the summary, the website code does not send these details to a server or store them persistently in cookies or browser storage. The copy function places the text on your clipboard. The download function creates a text file on your device. The email enquiry button passes the recipient, subject and content to your email application. The message only reaches SchadstoffCheck when you send it there.

This processing supports your requested enquiry preparation and, where relevant, steps prior to entering into a contract under Article 6(1)(b) GDPR. You control the storage or deletion of downloaded files, email drafts and clipboard content on your device.

4. Contact and assignments

When you contact us by email or phone, the contact details and content you provide are processed to respond and, where applicable, to prepare a quotation and carry out an assignment. The legal basis is Article 6(1)(b) GDPR for contract-related matters and Article 6(1)(f) GDPR for other correspondence. The legitimate interest is handling your enquiry.

Messages to Arghiyani@gmx.de are processed through the GMX mailbox and the email service providers involved. Data is only passed to other recipients where necessary for the assignment, required by law or covered by valid consent. Please provide only necessary information and avoid unnecessary personal data about third parties.

You are not obliged to submit an enquiry. Without the information needed to handle it or a way to contact you, it may not be possible to respond or carry out an assignment.

5. Retention and deletion

Contact and assignment data is processed for as long as necessary for its purpose. After an enquiry or assignment has been completed, it is deleted unless statutory retention obligations or legitimate grounds require further storage.

Business and tax records subject to retention requirements are kept for the applicable statutory periods on the basis of Article 6(1)(c) GDPR. Where retention is necessary to establish, exercise or defend legal claims, it is based on Article 6(1)(f) GDPR and takes account of the relevant limitation periods.

6. Cookies, external content and analytics

The website code provided by SchadstoffCheck does not set its own analytics or advertising cookies, use marketing or analytics services, or persistently store form entries in localStorage or sessionStorage. Typography and graphics are delivered with the website. Maps, videos and social networks are not embedded.

The information in section 2 also applies to technical processing by the hosting platform. Clicking an external link takes you away from this website; the relevant provider is responsible for subsequent processing.

SchadstoffCheck does not use automated decision-making, including profiling, within the meaning of Article 22 GDPR on this website.

7. Your data protection rights

Subject to the statutory requirements, you have rights of access (Article 15 GDPR), rectification (Article 16), erasure (Article 17), restriction of processing (Article 18) and data portability (Article 20). You may withdraw consent at any time with effect for the future; this does not affect the lawfulness of earlier processing.

Right to object

Under Article 21 GDPR, you may object to processing based on Article 6(1)(f) GDPR on grounds relating to your particular situation. Processing will then cease unless there are overriding compelling legitimate grounds or grounds relating to the establishment, exercise or defence of legal claims.

To exercise your rights in relation to SchadstoffCheck, use the contact details in section 1.

Right to complain

Under Article 77 GDPR, you may complain to a data protection supervisory authority. In North Rhine-Westphalia, this includes the State Commissioner for Data Protection and Freedom of Information North Rhine-Westphalia, Postfach 20 04 44, 40102 Düsseldorf: Complain to LDI NRW.
