External Services
SilverStream Invoicing connects to the SilverStream Digital licence server solely to validate Pro and Business licence keys. This only occurs when a user manually enters a licence key on the Licence page in Settings. No client data, invoice data or personal information is ever transmitted. Only the licence key and the site domain name are sent for validation purposes.
