A free, static, browser-based subscription tracker and recurring-cost calculator.

This is the best idea I can build and deploy without needing payment-platform, marketplace, email-service, Stripe, Gumroad, Payhip, Etsy, or ad-network credentials from the user.

It can be deployed as a static GitHub Pages site and can start collecting search traffic. It is not fully monetized yet because payment/affiliate/ad accounts require the user's credentials and tax/payment setup.

• tracks subscriptions and recurring payments
• calculates monthly equivalent cost
• calculates annual recurring cost
• estimates potential cancellation savings
• ranks cancellation candidates
• stores data locally in the browser
• exports CSV
• prints a cleanup report

4. Email capture
