Hi there,
I have reviewed your site, and can confirm that it is for non-commercial use only and therefore qualifies for our Free Stats plan.
I have made some changes on our end to reflect this. To continue using Jetpack Stats on your non-commercial site, you can now follow the flow on this page to certify that your site is non-commercial. You will be given the opportunity to make a contribution toward the service if you would like, or you can continue using the service without paying anything.
Let us know if you have other questions or if there’s anything else we can do to help!
