What stays in your browser
A few settings are saved in your browser's local storage so they are still there next time: your light or dark theme choice, and diagram editor preferences such as panel sizes and custom colour palettes. This data stays on your device. It is not sent to us, and it is not shared across devices.
Clearing your browser data, or using a private window, will remove these settings. Edited diagrams are not saved on the site, so download any you want to keep.
Fonts in the diagram editor
The site's own font is served from this site. The diagram editor's font picker loads extra fonts from Google Fonts, which means your browser contacts Google when you use it. Diagrams you download from the editor also reference Google Fonts, so opening an exported SVG in a web browser may contact Google too.
Hosting
Like any website, the hosting provider may keep standard server logs, such as IP address, browser type and the pages requested, for security and reliability. These logs are not used to identify you.
