Privacy

This notice explains how personal data is processed when you visit this website or contact us.

1. Controller

2. Providing this website

When you visit this website, technically necessary connection data is processed. This includes your IP address, the date and time of access, requested files, HTTP status, data volume and browser information about your browser, operating system and, where transmitted, the previous page.

This processing is necessary to deliver the website, maintain stability and prevent abuse. The legal basis is Article 6(1)(f) GDPR. Our legitimate interest is the secure and reliable operation of this website. Access is technically impossible without the necessary connection data.

3. Hosting

Web hosting is provided by united domains GmbH, Gautinger Straße 10, 82319 Starnberg, Germany. The hosting provider processes connection data and server logs for technical operation. Access is limited to recipients where necessary for provision, security or legal obligations. Server logs are retained only as long as necessary for technical operation and security analysis; longer retention may be necessary to investigate specific security incidents. Further information is available in the provider’s privacy notice.

4. Contact form and email

When you contact us, we process your name, email address, selected topic and message. Providing a company name is optional. We use this information to handle your enquiry and related correspondence. The form transmits the information to our web server over an encrypted connection, and the server forwards it to our mailbox by email. Message contents are not additionally stored in a website database. The hosting and email transmission providers necessary for this communication are involved in processing.

If your enquiry concerns entering into or performing a contract with you, Article 6(1)(b) GDPR is the legal basis. For other enquiries and enquiries made on behalf of a company, processing is based on Article 6(1)(f) GDPR. Our legitimate interest is responding appropriately to your enquiry.

We retain your information as long as necessary to handle your enquiry and any subsequent business relationship. It is then deleted unless statutory retention requirements or legitimate reasons to establish, exercise or defend legal claims apply. Required fields are necessary to handle an enquiry through the form. You may also contact us by email.

Providing and using your information

You are not legally or contractually required to submit an enquiry or provide information in the form. The form cannot be submitted without the required fields. We cannot reply by email without a working email address. Please do not submit passwords, payment details or health data.

Retention and deletion

For enquiries that do not lead to a contract, the relevant criteria are whether the enquiry has been fully answered or withdrawn and whether any follow up questions remain. If no other retention ground then exists, the information is to be deleted. If a contract follows, further retention depends on performance of the contract and applicable legal obligations.

Where correspondence qualifies as a business letter or accounting record subject to statutory retention, the statutory periods apply. Under Section 147 AO, these are generally six years for business letters and eight years for accounting records, calculated from the legally defined year end. Retention to comply with legal obligations is based on Article 6(1)(c) GDPR. In a specific dispute, necessary records may be required until proceedings and resulting claims are resolved, based on Article 6(1)(f) GDPR. These potential periods do not justify blanket retention of every enquiry.

5. Contact form protection

To protect against automated bulk messages, a daily pseudonymised network identifier and timestamps are processed when valid form enquiries are submitted. This protection does not store the full IP address or message contents. Entries older than one hour are removed on the next valid form enquiry. Processing is based on Article 6(1)(f) GDPR and our legitimate interest in the security and availability of this contact method. A form field hidden from human visitors also helps identify automated input. No external captcha service is embedded.

6. Cookies, analytics and external content

The website we provide does not set cookies or use local browser storage to recognise visitors. It does not embed advertising trackers, audience analytics or external captcha services. Fonts, graphics and scripts are loaded directly from this website. The language is determined by the page address. These functions therefore do not require a consent banner.

External links only connect to the destination website when clicked. The respective operator is responsible for processing on that website.

7. Your rights

Subject to the applicable legal requirements, you have the following rights:

1. Access to your personal data under Article 15 GDPR.
2. Rectification of inaccurate data under Article 16 GDPR.
3. Erasure under Article 17 GDPR.
4. Restriction of processing under Article 18 GDPR.
5. Data portability under Article 20 GDPR, where applicable.
6. Withdrawal of any consent with effect for the future. This does not affect the lawfulness of processing before withdrawal.

To exercise your rights, contact post@bergal-ki-welt.de.

8. Right to complain

Under Article 77 GDPR, you may lodge a complaint with a data protection supervisory authority, particularly in the country of your habitual residence, place of work or the alleged infringement. In Lower Saxony, you may contact the State Commissioner for Data Protection, Prinzenstraße 5, 30159 Hannover, Germany. Information and the complaint form are available at lfd.niedersachsen.de/beschwerde.

9. No automated decision making

This website does not use an AI model to process form submissions. No automated decisions with legal or similarly significant effects are made. Data processing and responsibilities for individually agreed AI services will be specified separately.

10. Project planner and downloads

The project planner processes your selections only in your browser’s working memory. Selections are transmitted only when you add the summary to a contact enquiry and submit it. No cookies or persistent browser storage entries save your plan. Downloads are generated locally in your browser. Downloaded files remain on your device until you delete them.

This technically necessary processing provides the planning function you request. The legal basis is Article 6(1)(f) GDPR; our legitimate interest is helping users prepare focused project enquiries. A subsequently submitted enquiry is processed as described under “Contact form and email”.

11. Technical presentation

The website uses the browser’s reduced motion preference only locally for presentation. The effects control changes presentation on the current page. This preference is not persistently stored or transmitted to us.

12. Changes

If we change website features or providers, we will update this notice to reflect the actual processing. The version published here applies.
