I am sorry you feel this way. I prefer going this route, as I would never sell user data or chose other means of monetizing my extension which may put user privacy or user thrust in jeopardy. At least now you can continue to enjoy Cookie-Editor knowing that your privacy is safe and that I will be able to justify putting more effort in this product that so many people enjoy and use to boost their productivity. I am always considering my options and ads might come and go with time depending on my needs.

Yes, Cookie-Editor does contain small non intrusive ads at the top. You can dismiss them and the same ad won't show up anymore.
Rest assured that Cookie-Editor still remains completely offline and no data is shared anywhere. I've put a lot of effort making sure Cookie-Editor could provide the best experience possible.

This is now part of the new update! In the options page, you can configure to show a secondary value in the interface.
