E-mail: DC@Duscons.com

The controller is the natural or legal person who alone or jointly with others decides on the purposes and means of processing personal data.

2. Hosting and server log files

This website is hosted by ALL-INKL.COM – Neue Medien Münnich, Inhaber René Münnich, Hauptstraße 68, 02742 Friedersdorf (All-Inkl). When you visit the website, All-Inkl processes technically necessary data such as IP address, date and time, requested page, referrer and browser information in order to deliver the website and keep it secure. Legal basis: Art. 6(1)(f) GDPR; our legitimate interest is the reliable provision of the website. Log file retention: [to be completed].

We have concluded a data processing agreement with All-Inkl. More information: all-inkl.com/datenschutzinformationen.

3. Storage in your browser (cookies and localStorage)

We do not set cookies for analytics or marketing and do not embed tracking, statistics or social media services. The following entries are stored in your browser:

dc_consent (localStorage) – your privacy choice, time and version. Strictly necessary under § 25(2) no. 2 TDDDG.

dc_theme (sessionStorage) – your display preference (light/dark) for the current session. Strictly necessary; deleted when you close the browser.

dc_theme (localStorage) – your display preference permanently, only if you consented to “Preferences” (§ 25(1) TDDDG, Art. 6(1)(a) GDPR).

You can change or withdraw your consent at any time via “Cookie settings” in the footer. Withdrawal deletes the permanent entry.

4. Fonts and external resources

Fonts, scripts and images are loaded exclusively from our own server. No connection is made to Google Fonts, content delivery networks or other third parties.

5. Contacting us

If you contact us by e-mail, phone or WhatsApp, we process your details to handle your enquiry (Art. 6(1)(b) GDPR for pre-contractual enquiries, otherwise (f)). The forms on this website do not transmit data to our server: they open your e-mail program with a prepared message that is only sent if you send it yourself.

The WhatsApp button is a plain link. Only when you click it does WhatsApp open (provider: WhatsApp Ireland Limited), and its privacy terms apply; no data is sent to WhatsApp before that.

6. AI Business Check

The AI Business Check is calculated entirely in your browser. Your answers are neither stored nor transmitted to us, unless you send the result by e-mail yourself.

7. External links

Links to external services (e.g. LinkedIn or partner websites) are only loaded when you click them. The respective provider is responsible for data processing on those sites.

8. Retention and recipients

Unless a more specific period is stated, your data remains with us until the purpose of processing no longer applies. If you make a legitimate request for erasure or withdraw consent, your data will be deleted unless statutory retention periods (e.g. under tax or commercial law) apply.

We only pass personal data to external parties if this is necessary to perform a contract, if we are legally obliged to do so (e.g. to tax authorities), if we have a legitimate interest under Art. 6(1)(f) GDPR or if another legal basis permits it. Processors are only used on the basis of a data processing agreement.

9. SSL/TLS encryption

For security reasons this website uses SSL/TLS encryption. You can recognise an encrypted connection by “https://” in your browser’s address bar.

10. Your rights

You have the right of access (Art. 15 GDPR), rectification (Art. 16), erasure (Art. 17), restriction (Art. 18) and data portability (Art. 20), and the right to withdraw consent at any time with effect for the future (Art. 7(3)). Processing carried out before withdrawal remains lawful.

Right to object (Art. 21 GDPR): where processing is based on Art. 6(1)(e) or (f) GDPR, you may object at any time on grounds relating to your particular situation. We will then no longer process your data unless we can demonstrate compelling legitimate grounds or the processing serves the establishment, exercise or defence of legal claims.

You may lodge a complaint with a supervisory authority, in particular in the member state of your residence, workplace or the alleged infringement. The authority responsible for us is the State Commissioner for Data Protection and Freedom of Information of North Rhine-Westphalia (www.ldi.nrw.de).
