A family tree that stays on your machine
View, edit and print your family tree without uploading it anywhere. The app runs in your browser; the data is one file on your own disk. Free, no account, and it prints a full-circle fan chart.
The sample is an invented family of 75, opened in memory. It never touches an archive you already have here.
In a JSON file you pick, on your own disk, or in this browser's private storage until you pick one. Nothing is sent to a server; there is no server holding a copy.
Open the browser's developer tools, watch the network tab, and use the app. After the page loads, nothing leaves. Pull the network cable and it keeps working.
A full-circle descendant fan built to be printed and handed to somebody, and a navigable tree for walking a line in both directions on screen.
The Archive page downloads a lossless JSON copy or a GEDCOM for other genealogy software, and keeps undo points before anything that replaces the archive.
Chart links only work in the browser that holds the archive. To share a chart, send a picture or a printed sheet. Why this exists.
