CiaoSpam

Ciao Spam is an Android app that automatically filters spam calls using the system's CallScreeningService API. Once set up, it evaluates each incoming call against seven blocking strategies and silently decides whether to allow or reject it—without you having to do anything.

🔒 SILENT PROTECTION
The app works in the background. You don't do anything; it filters everything. Each incoming call is evaluated in milliseconds against a series of configurable strategies. If it's spam, it's blocked. If it's legitimate, it goes through. It's that simple.

🛡️ 7 BLOCKING STRATEGIES
1. Blacklist — Block specific numbers you choose
2. Whitelist — Trusted numbers that are never blocked
3. Unknown Numbers — Block numbers not in your contacts
4. Hidden Numbers — Block private and anonymous calls
5. Custom Rules — Block by prefix, country, regular expression, exact match, content, or length
6. Time Zones — Block calls during specific times (e.g., do not disturb at night)
7. Spam Reputation — Block numbers with a spam reputation

📊 DASHBOARD AND STATISTICS
