A logger for the work that providers you pay push onto you: codes that fail, apps you didn't ask for, forms asking for things they already know, and unsubscribe links that go nowhere.
Households use it through a private link. This is a small trial; there's no public sign-up. If you've been given a link, open it and add it to your home screen.
Households can choose to pool their counts. Pooled results are published only when at least 3 households logged the same provider, so no one household can be picked out.
