STL Segmenter is a browser-based tool. Your STL files are processed entirely in your browser and are never uploaded to our servers. We do not see, store, or transmit your 3D models.
If you choose to leave a tip, you are redirected to Stripe. We do not see your payment card details. Stripe processes the payment under its own privacy policy. The information we receive from Stripe is limited to: the tip amount, an anonymized transaction ID, and (if you provide it) your email so we can send a receipt or thank-you note.
The app is hosted by Cloudflare. Cloudflare may log standard request metadata (IP address, user agent, request time) for abuse prevention and operational purposes under Cloudflare's privacy policy. We do not access these logs except to investigate abuse.
Because we do not collect personal data directly, there is typically nothing for us to delete. If you have left a tip and want your email record removed, contact us (see below).
This service is not directed at children under 13.
If we change this policy, we will update the date above.
