Can Session Activity Helper prevent every Training portals timeout?
No. It can help supported Chrome tabs stay visibly active, but it cannot override website, workplace, school, browser, device-management, or administrator-controlled session rules.
Does it move the real mouse cursor or keep the computer awake?
No. Session Activity Helper is browser-only. It sends visible browser activity on supported pages; it does not move the operating-system cursor or prevent device sleep.
What should I test before relying on it?
Open the exact web app tab you care about, run Test this page, start a visible session, and confirm the last pulse, active recipe, and support state in local diagnostics.
When is Pro worth it?
Pro is for repeat workflows: saved site profiles, longer run windows, advanced recipes, optional auto-start on saved domains, and exportable support diagnostics.
