Learn how we handle your personal information and ensure your privacy and data security on our platform.

Last updated: 20 October 2026.

1) Introduction and Contact

Information of the Data Controller

1.1 Thank you for visiting our website. Below, we inform you about how we handle your personal data when you use our website. Personal data refers to all data that can be used to identify you personally.

1.2 The controller responsible for data processing on this website, in accordance with the General Data Protection Regulation (GDPR), is Layer One GmbH, Warmbüchenstraße 30, 30159 Hannover, Germany, Tel.: +49 511 12290323, Email: hello@mail.layer-one.io. The controller decides alone or jointly with others on the purposes and means of processing personal data.

2) Data Collection When Visiting Our Website

2.1 When you use our website purely for informational purposes, we collect only the data that your browser automatically transmits to our server (so-called "server log files"). This includes: - Pages visited - Date and time of access - Amount of data sent (in bytes) - Source or reference from which you accessed the page - Browser used - Operating system used - IP address (possibly anonymized) The processing is carried out in accordance with Art. 6 (1)(f) GDPR based on our legitimate interest in ensuring the stability and functionality of the website. 2.2 This website uses SSL or TLS encryption for security reasons and to protect the transmission of personal data and other confidential content (e.g., orders or inquiries to the controller). You can recognize an encrypted connection by the "https://" prefix and the lock symbol in your browser's address bar.

3) Hosting

This website is hosted on Google Cloud Platform in Germany. Its static pages, fonts, images, scripts and 3D scene are delivered from our website address. To deliver a page, the hosting server processes technical request information such as the IP address, requested URL, request time and browser information. IONOS provides our email services. The booking calendar is provided separately by Cal.com, as described in section 14.

4) Analytics and advertising

No analytics or advertising pixels are configured on these website pages. The separately provided booking calendar is loaded only when you open it; information about that service is provided in section 14.

5) Cookies and browser storage

These public website pages do not require an account or analytics cookies. The Cal.com calendar is not loaded while you only browse the website. If you choose to open it, Cal.com may use its own cookies or browser storage. Its privacy information is available at https://cal.com/privacy. You can contact us by email instead of using the calendar.

6) Contact

If you contact us via email or contact form, we process your personal data solely for the purpose of handling your request. Legal basis: Art. 6 (1)(b) GDPR (contract) or Art. 6 (1)(f) GDPR (legitimate interest).

7) Use of Customer Data for Direct Advertising

We use your data for sending newsletters and other marketing measures, provided you have explicitly given your consent (double opt-in procedure). You can withdraw your consent at any time.

8) Web Analytics Services

This website uses no web analytics service. Google Analytics 4 is not loaded on any page. See section 4 for how this was measured.

9) Website Functionalities

This website embeds no map service and no customer review service. Our contact page carries a link to a map service so that you can find our address there. A link transfers nothing on its own; data reaches that provider only if you click it and thereby leave this website. While you are on our pages, nothing is loaded from Google.

10) Rights of Data Subjects

You have the following rights: - Right to access your data - Right to rectification and deletion - Right to restrict processing - Right to data portability - Right to object to the processing of your data - Right to lodge a complaint with a supervisory authority

11) Duration of Storage

Personal data is stored only as long as necessary for the respective purpose or as required by statutory retention periods.

12) Changes to the Privacy Policy

We reserve the right to update this privacy policy to reflect changes in legal requirements or our services. The current version is always available on our website.

13) 3D Graphic in the Page Header (Spline)

The header of our start page shows an interactive 3D graphic. It is displayed by the Spline viewer. Both the viewer program and the scene file are stored on this website and are delivered from our own address. Your browser does not contact Spline, unpkg or any other outside provider in order to show the graphic.

This was measured on 3 August 2026 against the delivered website, including the four preview pages on which the 3D scene runs: no request went to unpkg.com, none to prod.spline.design, and none to any other outside address. An earlier version of this website loaded both files from those two addresses, which meant that your IP address reached them. That is no longer the case.

The 3D graphic starts loading as soon as the page structure is ready, and it is loaded on every visit to a page that shows it. There is no fallback still image: if your browser cannot display the scene, the header keeps its plain background. Loading it contacts no address other than this website.

14) Booking appointments with Cal.com

We use the existing Layer One account on Cal.com for appointment bookings. The calendar connects to Cal.com only after you open it. Cal.com then receives technical information such as your IP address and browser information. If you book an appointment, the details you enter, such as your name, email address and message, are sent to Cal.com for that booking. This is the Cal.com cloud service, not a server operated by Layer One. Information from the provider is available at https://cal.com/privacy. You can instead contact us using the contact form or hello@mail.layer-one.io.
