Great for keeping you pure. Only issue I'm having is that the browser extension seems to be messing with my Gmail. Any time I use the search bar on the Gmail site, it bugs out and messes up the browser. I feel like it has something to do with the forced safe search, considering I'm on the browser Brave and that isn't a native feature to the browser, but it is still a fairly annoying issue that I hope can be looked into. Thank you for protecting our purity!

Great app, in conjunction with a few others can be very good - the only password protected image+video blocking app out there that I can find. Would be great to be able to allow permissions for image and video separately with password and maybe for a limited time-frame, certain times of a day and on certain websites only (this type of whitelist would help a lot!). Please keep improving the app and we'll be here for many years to come :)
