Hello Felix,
we have many ideas on how to keep Clipperz data usable on a mobile
platform, but for the near future we can not afford to work on them
(even if we are always trying to find new ways to finance .
If you look into this group messages, one user once posted a script he
was using to export his data in a CSV format. It could handle only
cards whose structure had some limitations (that I can not remember
right now), but may help in case you want to move your data out of
Clipperz.
Best regards,
Giulio Cesare
