Unfortunately, Miro is a hosted solution as it is primarily intended as a collaboration tool. There is an existing wish list idea which you could upvote here regarding offline access: https://community.miro.com/ideas/offline-mode-925

It’s  unfortunatly  one  of biggest problem with miro

no offline, no interoperability

As tool  to work with a lot of  people , It’s normal to don’t have an offline version.

But when you want to work alone before or after this collective time, you also have to be connected because it is not possible to do it with a different tool, and then import/export the data.

There is just a way to import "a photo" and export an image.
And each time start again
