Privacy & Cookie Policy

This Privacy & Cookie Policy explains clearly what data stays inside your browser, what network requests occur when you visit Macro Circuit (https://themacrocircuit.com), and how optional newsletter subscriptions are handled.

1. Local Browser Calculator Privacy & Shareable Scenario URLs

• Local Computation: When you type or adjust salaries, home prices, loan APRs, 529 balances, HSA medical estimates, retirement savings, or household budgets inside any of our 12 calculators, calculations run locally in your browser's JavaScript engine. Your calculator numbers are not transmitted to a Macro Circuit database when you use the sliders or number boxes.
• Browser localStorage Preferences: Convenience settings — your selected U.S. state (mc_v5_state), display currency symbol (mc_v5_currency), theme appearance (mc_v46_theme), and anonymous poll ballot token (mc_v5_voter_id) — are stored locally in your own browser and can be cleared anytime through your browser settings.
• Shareable Scenario Links & PDFs: If you choose to click Copy My Scenario Link, your current calculator inputs are encoded into that URL's query parameters (for example, ?v=2026.11&...) so the scenario can be reopened. Anyone with whom you share that link will see those entered numbers, and URLs may remain in your local browser history or standard HTTP logs if opened. 1-page PDF summaries are generated locally in your browser.

2. Optional Weekly Email Briefing (Cloudflare & Brevo Processing)

If you voluntarily subscribe to Free Weekly US Money & Economy Updates:

• What We Store: We record your normalized email address, signup timestamp, page source, subscription status, and a unique cryptographic unsubscribe_token on Cloudflare infrastructure, and synchronize your subscriber address with our authenticated email delivery processor, Brevo (Sendinblue SAS), solely to send your welcome confirmation and Sunday Macro Circuit briefings from [email protected].
• Zero List Selling: Macro Circuit never sells, rents, or brokers subscriber email addresses to third parties.
• One-Click CAN-SPAM Unsubscribe & Deletion: Every email contains a one-click unsubscribe header and direct opt-out link (themacrocircuit.com/unsubscribe/) that suppresses future mailings in both our subscriber registry and Brevo. For complete permanent record deletion, email [email protected].

3. Anonymous Topic Poll (/api/poll)

When you vote on upcoming documentary topics, a random browser-generated identifier is hashed with SHA-256 on the server solely to limit duplicate votes per topic without collecting your name or email address.

4. Infrastructure, Typography & Third-Party Network Requests

• Cloudflare Edge Hosting: themacrocircuit.com is served through Cloudflare's global edge network, which processes standard connection metadata (such as IP address and user-agent) for routing, DDoS protection, and security.
• Google Fonts: Pages load the Inter and JetBrains Mono typefaces from fonts.googleapis.com and fonts.gstatic.com. Your browser sends a standard font request (including IP address) to Google servers to cache and render these fonts.
• Click-Triggered YouTube Privacy-Enhanced Embeds: Video embeds are never auto-loaded with sound; when you choose to play a verified video, embeds use YouTube's privacy-enhanced domain (youtube-nocookie.com, autoplay=0) or open our official channel directly.
• Advertising & Cookie Choices: Where third-party display advertising (such as Google AdSense) is enabled, vendors may use cookies to serve ads based on prior visits. You can manage or opt out of personalized ads at Google My Ad Center and aboutads.info/choices.

5. U.S. State Privacy Rights (CCPA / CPRA / VCDPA / CPA / CTDPA / TDPSA)

Residents across all 50 U.S. states and D.C. may request access to, correction of, or deletion of any personal email record held by Macro Circuit by writing to [email protected].
