No Wikipedia account, no software. You will get a baseline confirmation email first — not a false alarm — then real alerts only when something actually changes.
Billed annually. Renews automatically; cancel any time to stop the next renewal. Payments are non-refundable, except where required by applicable law. After checkout you will verify your email, and monitoring activates immediately after.
