# Privacy

No account, no server, no telemetry. Your models, profiles and projects are files on your own disk, and the author never sees any of them.

## What the app connects to

This is the full list of network connections the app can make, and when.

| What                  | Where it goes                                         | When                                                        |
| --------------------- | ----------------------------------------------------- | ----------------------------------------------------------- |
| Sending a sliced file | Your printer, on your own network (SDCP or PrusaLink) | Only when you press Send                                    |
| Finding printers      | A UDP broadcast on your local network                 | Only when you ask it to look                                |
| Checking for updates  | github.com, over HTTPS                                | Off by default. Once on: daily, or when you press Check now |
| Downloading an update | github.com, the archive for your system               | Only when you press Install and restart                     |

An update check sends nothing but the request itself, and an update is only installed if it carries the project’s own signature.

## This website

This site sets no cookies, runs no analytics and loads nothing from other servers. Two small scripts read your browser’s preferred languages and your operating system, only to show you the right language and the right download; neither leaves your device. If you pick a language from the menu, your browser’s local storage keeps that choice (the language code and the date, nothing that could identify you) so the site doesn’t override it next time. The details, in German as the law requires, are in the [Datenschutzerklärung](https://encrust.app/datenschutz/).

Encrust prepares files for machines that cure resin with UV light. It can’t know whether your settings suit your resin, printer or model, so check what it produces before a long print. Provided without warranty, as the licence says.
