Can I use PitPat without providing any data to you?

Unfortunately not.

As we outlined above, we do need a certain minimum amount of information about you and your pet to be able to safely and securely identify you and them when we communicate with you, to understand your context (because we serve a lot of people with a lot of different needs) and to meet our legal obligations. But we do try to keep that to a minimum, and we let you skip over questions where we can by tapping NEXT without answering or by accepting the default answer that we provide whenever that's possible. We don't mandate things we don't have a real need for just because we're being nosy or curious!
