2. Processing of your STL files
STL files that you open in the viewer are processed exclusively locally in your web browser. No upload to a server takes place. The files never leave your device. Consequently, no storage, analysis, or disclosure by us takes place.
3. Server Logfiles
When you access this website, the following data is captured by the hosting provider by default in so-called server log files:
- anonymized or truncated IP address
- date and time of the request
- accessed page / file
- HTTP status code and amount of data transferred
- browser type and operating system (User-Agent)
- referrer (previously visited page)
The legal basis is Art. 6 para. 1 lit. f GDPR (legitimate interest in the secure and stable operation of the website). This data is not merged with other data sources and is deleted or anonymized after a maximum of 14 days.
4. Cookies
This website uses no cookies and uses no local storage for non-essential purposes. Therefore, there is no need for consent management (cookie banner).
5. Tracking, Analytics, Advertising
This website uses no web analysis tool, no tracking pixels, and no advertising scripts.
6. External Resources
To display 3D models, the three.js library is loaded via the public CDN unpkg.com. When this JavaScript file is loaded, your IP address is technically transmitted to the CDN provider. We have no influence on this. Legal basis: Art. 6 para. 1 lit. f GDPR (secure and lean delivery of the application). If you want to avoid this, you can, for example, block the scripts with a browser add-on.
7. Contact by E-mail
If you contact us by e-mail, the data transmitted with the e-mail (e-mail address, possibly your name and your message) will be stored to process your request. Legal basis: Art. 6 para. 1 lit. b or f GDPR. The data will be deleted as soon as it is no longer required for processing and no statutory retention periods conflict with this.
8. Your Rights
You have the right at any time to:
- Information about your stored data (Art. 15 GDPR)
- Rectification of incorrect data (Art. 16 GDPR)
- Erasure (Art. 17 GDPR)
- Restriction of processing (Art. 18 GDPR)
- Data portability (Art. 20 GDPR)
- Object to processing (Art. 21 GDPR)
- Lodge a complaint with a supervisory authority (Art. 77 GDPR)
9. Changes to this Privacy Policy
We reserve the right to adapt this privacy policy so that it always complies with current legal requirements or reflects changes in our services.
