Privacy policy

The key points first

Your 3D scans are opened and processed exclusively in your browser on your device. They are not uploaded, not stored on a server and not passed on to third parties. This website sets no cookies, uses no analytics or tracking tools and loads no content from third-party servers.

2. Hosting and server logs

This website is hosted by ALL-INKL.COM – Neue Medien Münnich, owner René Münnich, Hauptstraße 68, 02742 Friedersdorf, Germany. When you open the page, the web server processes technically necessary access data: IP address, date and time, requested file, amount of data transferred, status code, and browser type and operating system. This data is used solely to operate the website securely and reliably and is deleted or anonymised after a short time. It is not combined with other data.

The legal basis is Art. 6(1)(f) GDPR (legitimate interest in secure operation). A data processing agreement pursuant to Art. 28 GDPR is in place with the host.

3. Processing of your scans

Files you load into the viewer (e.g. .dcm, .stl, .ply, .obj) are processed only in your browser’s memory. Exports and patient files are also created directly on your device. I never have access to this data. The respective practice is responsible for sending patient files to patients.

4. Storage in your browser

The viewer stores a few settings in your browser’s local storage (localStorage): whether you have read the intended-use notice, your preferred orientation and language, the details for patient files (practice name, message, logo) and, if applicable, your Pro license key. This data remains on your device and is not transmitted. You can delete it at any time via your browser settings.

This storage is strictly necessary for the functions you request (§ 25(2) no. 2 TDDDG).

5. Pro licenses

A Pro license key contains the licensee’s name and the expiry date. The key is checked exclusively in your browser. If you request a license, I process your name and email address to send it to you (Art. 6(1)(b) GDPR).

6. Contact

If you contact me by email or phone, I process your details to answer your request (Art. 6(1)(b) or (f) GDPR). The data is deleted once it is no longer needed for this purpose and no statutory retention obligations apply.

7. PayPal (“Buy me a coffee”)

The coffee button is a simple link to PayPal. You are only redirected to PayPal when you click it; no data is transmitted to PayPal beforehand. PayPal (Europe) S.à r.l. et Cie, S.C.A., 22–24 Boulevard Royal, L-2449 Luxembourg, is independently responsible for the payment. For details, see PayPal’s privacy statement.

8. Your rights

You have the right to access, rectification, erasure and restriction of processing of your data, to data portability and to object to processing based on Art. 6(1)(f) GDPR. Simply contact kontakt@multimedic.de.

You can also lodge a complaint with a data protection supervisory authority, for example the Independent Centre for Privacy Protection Schleswig-Holstein (ULD), Holstenstraße 98, 24103 Kiel, Germany.
