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.
Implementing JSON import/export is at the top of my roadmap for persistence: letting users "save" their progress locally without needing a cloud backend.
I’m working on the data schema for this right now. Stay tuned!
As for privacy, everything stays in your browser. There’s no backend database tracking your family history.
The data is stored locally (via LocalStorage), so if you refresh the page or come back later, it’ll still be there—but I never see it.
