Mastering Your Subscriptions: The Ultimate Open Source Management Solution

Why You Need a Subscription Management System

In today’s digital landscape, subscriptions dominate our lives—from streaming services to cloud tools, the average user juggles 12+ recurring payments. Sound familiar?

  • Forgot renewal dates, leading to service disruptions?
  • Unsure of your total monthly subscription spend?
  • Struggling with multi-currency billing?
  • Can’t identify underused services?

This is where a dedicated subscription management system becomes indispensable. The open-source solution we’ll explore solves these pain points with surgical precision.

FAQs: Expert Answers

❓ “Can I use it with non-USD subscriptions?”

Absolutely. The system converts 7 currencies automatically. Even if your Netflix charges in EUR and iCloud in JPY, everything displays in your base currency.

🔒 “Where’s my data stored? Is it secure?”

All data stays locally in your SQLite database. For Docker deployments, use volume mounts (e.g., ./data:/app/data) for persistent storage. Zero third-party access.

💱 “How often are exchange rates updated?”

Rates refresh daily via TianAPI. No API key? Manually update currencies under Settings → Currencies.

📱 “Is there a mobile app?”

Not yet—but the responsive web UI works flawlessly on phones. Add it to your home screen as a PWA for app-like access.

🔄 “How do I migrate from spreadsheets?”

Go to Subscriptions → Import. Use our CSV template:

name,category,price,currency,billing_cycle,next_payment_date  
Netflix,Entertainment,15.99,USD,monthly,2024-08-05
