Some of the features in this extension use tools that I created and are hosted on SEOpen.com. I maintain stats and user logs like everyone else, but I don't mine the data for how the tools are used and I don't share any of the site information with anyone.
Some of the features in this extension use tools that I have no control over and are not hosted by me. I'm confident these web apps also maintain stats and user logs, but I cannot speak to how they use their data. I have tried to ensure SEOpen only utilizes legitimate, secure web apps.
