Subscription & Free Trial Manager

Build a subscription tracker that alerts you before charges and tracks days remaining on free trials.

Build a subscription and free trial manager (Digital Decay):

Subscription tracking:
- Add subscriptions with name, cost, billing cycle (monthly, yearly), next billing date, and category
- Track free trials with start date and trial length
- Set payment method per subscription
- Group by category: streaming, software, news, fitness, cloud, etc.

Alerts:
- Alert before free trial ends (configurable: 3 days, 1 day before)
- Upcoming billing reminders
- Price increase detection (manually log price changes)
- Days remaining countdown for each trial

Analytics:
- Total monthly and yearly subscription cost
- Cost by category breakdown
- Spending trend over time
- Cost per day calculation

Management:
- Mark subscriptions as active, paused, or cancelled
- Archive cancelled subscriptions with cancellation date
- Add notes (e.g., cancellation instructions, promo codes)
- Quick view: which subscriptions renew this week/month

The app should have user authentication. All data is private per user.

Visual style:
- Color palette: white background with warning red (#EF4444) for expiring trials and calm blue (#6366F1) for tracked subs
- Card list with countdown timers, cost summary cards, and calendar highlights
- Clean, practical sans-serif typography
- Consumer utility aesthetic — clear, alert-driven, like a smart subscription radar
