More info on data privacy

[VictorPuga]

I love this extension. It opens a lot of opportunities for multitasking. The only thing that I noticed is that when I add it to Safari on macOS is that it asks for permission to read website data and search history. I know that the biggest probability is that it is required for the functionality of the extension itself, so maybe a good idea would be to include a privacy policy or something that let us know the users of how our data will be managed/secured.

Keep the good work going!
