export sounds like an awesome feature to add .. I guess the format of the exported data is something I'd have to think about

[charbz]

any format in particular ? .. JSON would be the most natural , XML is possible .. plain text probably the most useful

Whatever would be simple and stable. So yaeh, JSON seems to be the obvious choice. I guess Firebase or your web-framework is already using it internally?

Export is the natural downfall of every cloud-solution. Because if people have no way to get their data, many will not bother to bound with a closed up tool.
