S3Drive can be used in a self-hosted mode, being fully offline.

The challenge is that paid users (Ultimate, Business) might need 100% offline solution, where they connect only to their internal network. In such case verifying a license wouldn't work, as currently user needs to login to their S3Drive account.

This task is to implement offline licensing.

As an example, app could generate a code which could then be "signed" on the app/website with the internet connection. This signed verification code could be then re-imported back to the app for an offline use.

The exact implementation details might change, as long as we get to this.
