Whatever you put on a board — the org chart, the plan, the venting — stays in your browser's storage on your machine. There is no server-side application to receive it.
Every stroke auto-saves to local storage under this site's origin. Nothing syncs, nothing uploads. The .board and PNG exports are files written straight to your downloads by your own browser. Delete boards by wiping them here or clearing site data; I hold no copies to delete.
No analytics, no ads, no cookies of mine. One font family loads from Google Fonts on first visit (their standard request logging applies; cached afterwards). Cloudflare hands me anonymous page-view counts. That is the complete surveillance apparatus: a number.
Local storage is tied to this browser on this device — a shared computer means shared boards. On a library machine, wipe your board and clear site data when you leave, same as you'd erase a physical whiteboard in a shared room.
