Yes — install the FlowLock extension free from the Edge Store (or Chrome Web Store). The free version highlights when sensitive data is being typed into websites so users are aware, but it does not block anything. There is no local logging; instead, key events are surfaced via desktop notifications. Upgrade to a paid plan to unlock blocking, the cloud admin console, team policies, and historical dashboards.
Only content matching your policies is evaluated, and matches are processed on-device. Nothing is sent to FlowLock servers unless a policy explicitly logs the incident.
Yes. Plans are billed monthly or annually and you can upgrade, downgrade, or cancel at any time from billing settings.
