Entries are processed only in the browser. No client invoices, names, email addresses, dates or amounts are sent to our server. This version collects only aggregate anonymous daily usage-event counts (page visits, completed calculations, relevant link clicks and coarse acquisition categories) through Cloudflare D1, without account identifiers, cookies, personal invoice data or the full referrer URL. Cloudflare hosting itself may handle IP addresses and technical request data for hosting and security. Outbound email links open your own email application and are not sent by us.
