That window is about Sprwt's own platform terms, not your website's. When Sprwt publishes a new terms revision (currently dated 2026-08), every business admin user who hasn't yet acknowledged it is shown the Security update – Updated Terms & Conditions dialog with a link to read the updated terms at sprwt.io/terms. It cannot be dismissed with ESC or by clicking outside; click OK to acknowledge — the click is recorded on the server before the window closes. Your acknowledgement is recorded per user and the dialog will not appear again until the next revision. It is not shown to Sprwt super-admin (staff) accounts or to onboarding accounts, since those aren't the account holder being asked to accept.
