We do give credit in the licenses file. The reason we don't mention it on the site yet is because Relica currently ships with rclone but we do not use it, yet. We will be using it once we flip the switch to activate some new features soon!

We've also made a few contributions to rclone and restic so all the work we do on open source projects is available upstream to the main project's users.

It's built on top of restic, not rclone.
