Calculator data
Subscriber counts, billing choices, and required-feature selections are processed in your browser. This MVP has no application backend or database that receives those calculator inputs.
Accounts, email, and payments
The site does not offer user accounts, comments, saved comparisons, an email subscription form, or online payments. Do not send sensitive information through the calculator because it is designed only for aggregate subscriber counts and feature preferences.
Hosting and technical logs
The site is intended to be hosted on Cloudflare Workers Static Assets. Cloudflare may process standard network and request information for delivery, reliability, abuse prevention, and security under its own policies. Newsletter Cost Guide does not promise that infrastructure logs contain no personal data.
Cloudflare Web Analytics
The site uses Cloudflare Web Analytics to measure page views and page-load performance. Its browser beacon collects timing metrics through the Performance API. Cloudflare states that Web Analytics does not use cookies or local storage for usage metrics and does not track individual visitors across its customers' websites.
External links
Provider and documentation links take you to third-party websites. Those websites control their own cookies, analytics, forms, and privacy practices. Opening an official pricing page is subject to that provider's policy.
Policy updates
If email collection, accounts, payments, or other data-handling features are added later, this policy and the changelog must be updated before those features launch. Last updated: .
