Support for Backups and Open Data Formats

It would be awesome to have a backup option for pomodoro data. If the app could export using an open format (JSON, XML, CSV), users could easily move their data into other tools or workflows with just a bit of conversion.

I'm interested in this. Is there a standard format for exporting data from timer apps? If there isn't, maybe I'll just export it using a JSON schema derived from scratch (or maybe I'll export the SQL database tables as CSV files)
