Sorry the extension is no longer a fit for you. More info on why "browsing activity" and "website content" are necessary is covered here: https://knockoff.co/privacy

Any decision I make will be a positive for some a negative for others. Such is the nature of creating things. The code for the earlier versions *is* very much open source and you're more than welcome to download, use, fork, etc: https://github.com/Shpigford/knockoff
