No. Rendering happens entirely in your browser and the scene is saved to localStorage — nothing is uploaded. You can export a file any time for backup.
PNG, SVG and the .excalidraw source file, plus copy-PNG-to-clipboard. PNG suits pasting into docs, SVG scales as vector, and .excalidraw lets you continue editing later.
No. It lives in this browser’s local storage, so switching device, browser or clearing site data loses it — export a file from the menu to be safe. Make a habit of exporting important sketches.
Yes. Rectangles, diamonds, ellipses, arrows, text and freehand are all built in, and snapping makes flowcharts and architecture diagrams straightforward; for collaboration, export the file and share it.
The board and its sketch fonts are a few megabytes; the first visit downloads them and the browser caches them afterwards. On a slow network, wait for the fonts to finish loading.
The board is built on the open-source Excalidraw project (MIT licence). We self-host its font assets and adapt it to this site’s style; the underlying rendering remains the open-source code, with no changes to encryption or privacy logic.
Standard Excalidraw supports embedding images as elements; if the current build does not expose it, convert the image to a link or screenshot and annotate its reference with arrows.
Local auto-save overwrites in place and cannot auto-recover deletions. The reliable way: at key points, manually "Save to file" export .excalidraw, and confirm a backup before closing the page.
