todo syncing with replicant

Does anyone have recommendations for a TODO application that I can use on both Replicant and Trisquel? I'd rather it not be hosted by a third party and I don't mind manually making the sync when I connect my phone (moving files or whatever).

I already use Tasque and I installed Mirakel, but I haven't done any digging to see if the two can export or do any sort of sync.

Thanks!
