- No user-generated geometry, previews, or parameter settings are stored.

3. Local Processing by Design
- Parsing, previewing, and converting 3MF files happen locally in your browser.
- Files are never uploaded to our servers for processing or storage.
- Converted STL files remain on your device.

4. Limited Technical Data
- We may record anonymous, aggregated metrics (page views, feature usage, error rates, device/browser type).
- IP addresses may appear in transient server logs for security and performance; logs are routinely rotated and not linked to individuals.

5. Cookies and Local Storage

- You can clear cookies/local storage in your browser at any time.

6. Third-Party Services

- Minimal data collection; no customer databases for uploads.
- Regular dependency and infrastructure updates.

8. Your Choices and Rights
- Block or clear cookies/local storage via browser settings.
