Pro adds visitor save-and-resume, encrypted incomplete applications, retained draft attachments and private links. Free retains administrator draft recovery, ordinary multistep forms, completed-submission private uploads, simple estimates and print summaries, inbox, CSV and queued email.

The feature split has no parallel legacy edition. Existing source history and stored data are preserved. Install Free first, then matching Pro. Deactivation does not delete data.

Free needs no commercial activation. From Pro 0.12.2, the separate Pro companion requires an initial site licence activation for its editing and tools. Install matching Free before updating Pro; see the Pro readme for its activation and update policy.
