Browser-based logseq should persist data locally when transitioned to DB version

I am currently using logseq on browser, using the https://demo.logseq.com/#/. I am able to ensure that the data are always saved on my device, I read that logseq is going to have a DB version, and I tried the web-based version https://logseq-db-demo.pages.dev/, while I can import my current files and edit without any issues, I am concerned that it no longer write the changes back to my device. I know that it is stored somewhere in the indexed-db or something of the likes.

Is it possible to save the sqlite or the file (or both) locally similar to what the current web app allow, rather than me having to do export/import repeatedly? Not sure if it’s being planned or if the feature is to be dropped.
