We support OPML and XML formats. If
TickTick does not support
exporting in these formats, you can send to
sup...@mylifeorganized.net your file (or a part of it) in the format they support. We will check if it can be
imported properly to MLO. We treat all the data files provided by users very carefully, respecting your privacy. The file is deleted immediately after resolving the problem and is not saved anywhere.
