2. Hosting and server logs
The website is hosted by ALL-INKL.COM, Neue Medien Münnich, Hauptstraße 68, 02742 Friedersdorf, Germany. When a page is requested, the server processes technically necessary data: IP address, date and time, requested page, amount of data transferred, status code, referrer, and browser and operating system. I need this data to deliver the website securely and reliably. The legal basis is Art. 6(1)(f) GDPR. The logs are stored only for as long as necessary for this purpose. A data processing agreement is in place with the provider.
3. Fonts
The font Inter is stored on my own server. No connection to Google Fonts or other font providers is made when a page is loaded.
4. Storage in the browser
If you switch between light and dark display, your browser remembers this choice in local storage (localStorage). This information does not leave your device. If you select “System”, the entry is deleted. The legal basis is Section 25 (2) No. 2 TDDDG (German Telecommunications Digital Services Data Protection Act).
5. Analytics with Seline
To understand how the website is used, I use Seline (Seline Analytics, ul. Łowicka 60/16, 02-531 Warsaw, Poland). The script is loaded from a Seline server. The data collected includes the pages viewed, the previous website (referrer), campaign parameters in the address (UTM), the country, and the browser, operating system and device type. In addition, there are individual events not linked to you as a person: whether frequently asked questions are expanded, references are opened, the display mode is switched or the appointment booking is used.
Seline sets no cookies. To count visits within a day, Seline creates a hash from the IP address, browser identifier, domain and a random value that changes daily; the IP address itself is not stored, and the random value is deleted after 24 hours. This does not create a profile across several days. The data is stored on servers in the EU. The legal basis is my legitimate interest in privacy-friendly analysis (Art. 6(1)(f) GDPR). You can object by using a tracking blocker or by writing to me. More: seline.com/privacy.
6. Booking an appointment for the intro call
On the “Contact” page you can book an intro call. For this I process your name, email address, optionally your company, your industry, your expectations for the call and the appointment you choose. The purpose is to prepare and hold the call. The legal basis is Art. 6(1)(b) GDPR (steps prior to entering into a contract).
Appointments are managed in the booking tool Fluent Booking on the website busical.ai of busical AI GmbH, which acts on my behalf for this purpose. A data processing agreement is in place with it. Your browser communicates only with my server; my server checks for available times and creates the booking. You receive an invitation by email.
As soon as you submit your details in the first step, that is, before you choose an appointment, I add you as a contact in my customer management system FluentCRM. It also runs on busical.ai at busical AI GmbH, under the same data processing agreement. This lets me get in touch with you if choosing an appointment does not work. You will not receive newsletters or advertising as a result.
The call takes place via Google Meet (Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland). Data is transferred to Google only when you open the link; this may involve a transfer to the USA, which is based on the EU-US Data Privacy Framework. If you do not want to use Google Meet, write to me and we will find another way.
I delete the data when it is no longer needed for the call and any possible collaboration and there are no statutory retention obligations.
7. Spam protection
The form uses ALTCHA: your browser solves a small computing task before it submits the form. This runs entirely on your device and my server, without third-party services and without cookies. The legal basis is my legitimate interest in protection against misuse (Art. 6(1)(f) GDPR).
8. Contact by email
If you write to me, I process your details to answer your inquiry. The legal basis is Art. 6(1)(b) GDPR for questions about working together, otherwise Art. 6(1)(f) GDPR.
9. External links
Links to other websites, such as busical.ai or LinkedIn, open only after you click them. The privacy notices of the respective provider then apply.
10. Your rights
You have the right to access (Art. 15 GDPR), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), data portability (Art. 20) and to object to processing based on legitimate interests (Art. 21). You can withdraw any consent you have given at any time. To do so, write to info@stueckmann.com.
You can also lodge a complaint with a data protection supervisory authority, for example the State Commissioner for Data Protection and Freedom of Information of Baden-Württemberg.
