When the windows version will be launching as I use windows system mainly. Any approx TAT?

windows version for Blurscreen app is live for months now, check videos on homepage https://www.blurscreen.app

So hiding the URL is only possible on the https://www.blurscreen.app/ but not on https://blurmypage.web.app/? Do you have to go for the bigger deal for that feature?

blurweb.app cannot hide url since its browser extension i recommend to try blurscreen.app for that, https://appsumo.com/products/blurscreen-app
