I like that it makes the process of asking for permission to use your data easy - we've found it much easier than other tools! It's not really clear what happens when you cancel consent (I'm assuming this is because there isn't one). If users don't understand why they need to give us access to their data then how can we expect them to trust our service? We're solving an important problem by helping people make more informed decisions about sharing their personal data while also giving them control over who has access to it.
