To which public free service can I export data from my site?

Question

API

Good afternoon. Not sure which section to label.
Bewildered since morning.
Are there public services (a la keep, evernote) to which I could export data from my site?
Notes, banal todo, etc. To be able to work with them.

Answer 1

There is such a thing: https://backendless.com
There is a database, an API editor, and Auth 2.0.
The free plan for personal use is fine.
