Great.
Please:
1. Do away with the browser plugins and come out in the open about your tracking and storing private user data.
2. Develop a backend or service that we can use on other clients as well, not just inside your almost ugly and non-intuitive browser plugin powered website.
3. Finally, set a price. People, who love their services and become dependent on them don't like to see them sink and/or read my private data to sell not to avoid the sinking. If you are free you are doing sth fishy because no-one can believe you receive grants for Greenpeace or PETA.
4. Keep my data exportable and takeout ready at any time, in a format that I can use elsewhere i.e. Have your service conform to some standard standard(preferably "open" open, not Google's open).
