 ## Privacy Consideration
 
-Please consider, that this extension has access to all the images you browse and stores compressed copies of them on my Amazon S3 bucket for up to 3 days.
-If you don't want your images to be stored on some stranger's server, you can run your own proxy server.
-
-You will need a free Heroku account and an Amazon AWS account, 
-which is also available for free for up to one year, 
-and after that it costs just pennies per gigabyte of traffic.
+Please note that proxy server does not store the images anywhere, it compresses them on the fly.
+However if you want to be 100% sure you can run your own proxy server instance.
