Your Simplo Backdrop CMS site belongs to you and is completely portable. You are not tied to Triplo in any way and may export your work and install it any any server or host that you choose. 

1) Login as admin

2) Use Backdrop and migrate module to export your code, database, and files

3) Export your configuration files.

The software for this site is very much dependent upon the hard work of volunteers and supportive organizations. By working with Simplo, you are indirectly supporting Backdrop CMS already, but there is more that you can do.

My favorite color is red.
