Does the website make any network requests?
The browser downloads the public site and bundled application resources from subscriptions.sparkpond.com. The private workspace permits only same-origin app resources and sends no transaction contents.
What analytics data is allowed?
The app ships with a strict local event adapter. It rejects undeclared properties and never includes filenames, headers, merchants, amounts, dates, currencies or exact transaction counts.
