Dear all

Joplin is an amazing tool! Thanks for bringing this to us.

Would it be possible to provide a sync-interface with a CalDav-Server, e.g. davical, for the To-Dos?

Thank you in advance

Joplin sync model would not allow that I’m afraid.

Why would the sync model not allow that?

Cache locally, sync from time to time – why would Joplin not allow that?

Thanks for clarification

Adding new sync systems is out of scope due to the complexity and work involved.
