Honest fine print
- Alerts come from the same automated page checks plus a human review, so “same day” means within about a day of detection, not real-time.
- We don’t invent data: exports contain exactly what the site shows, plus history.
- The site, API and weekly email stay free. Pro pays for the time to keep them accurate.
