Love the simplicity. Most family tree tools are so bloated that it feels like a chore just to add a cousin. One quick question: Since it runs entirely in the browser, are the family names and data stored locally, or do you have a backend keeping track of the trees? Privacy is always a big concern for people when it's about family history.

I always wanted to make such a tool for myself but never sat to actually build it. User experience was a breeze.

I see that there is no import button. Adding Import will help many of us to keep editing the same tree instead of building it from scratch everytime. You can add a JSON export of the tree and then users can import this JSON to make edits. I can also share this JSON with other family members.
