User reviews

I am the weird one always reading T&C and tick off all the box to NO DON'T SAVE ANYTHING but it always annoys me they can collect and use if they want. Thank you so much and I strongly support your research!

Very good idea, looking forward to what they discover.

I'm giving you a review to ask a question, since I can't find another way of doing it within the store. Of course, the amount of stars reflect how I feel at the moment about the extension. So here's the question: Will it work if I have Ublock Origin installed? Will you still see what you'd like to see?
