Privacy
Nothing is uploaded. The file is read by JavaScript in the browser tab; conversion and rendering happen on the device. Closing the tab removes it.
What the site stores
The viewer keeps your theme choice and, if you open a file from a guide page, the file is handed to the viewer page through the browser's own IndexedDB storage on this device and removed as soon as it is opened. No file content is sent to any server.
Analytics
Page views are counted with privacy-respecting analytics without cookies. Error reports contain the file name, size and the error text, never the drawing itself.
