Export options were my first thought too. The bottom of their website [1] says, "Your data is yours and you have full conrol over it, so you can export or delete it at any time." I'm curious what that actually means though... how can I export it, and to what formats?
JSON, through the web interface. I'm a journaling geek, so I signed up to try Narrato. After you confirm your email address, it takes you to their online account manager, which has an export button. The export looks like a JSON file, plus a directory all of the images that you've uploaded to the app.
Can you describe a good export experience for the average person? Google takeout service is pretty similar (I think, I have not actually in-archived my files to inspect them).
I am genuinely curious because I use my wife as the average person when it comes to technology and she has absoluy no interest in exporting her stuff from Google. I do it because I have grand ideas of a personalized data store with search tha I can just dump stuff into so my grand children's grandchildren can search for stuff and discover their history through our data.
