## What is CallDam?

CallDam is built for mass call blocking by phone-number prefix.

Instead of blocking one unwanted number at a time, CallDam lets you create prefix rules that can protect thousands of related numbers at once. The app is designed for large blocking lists, with support for up to 1.8 million active protected numbers.

A key feature is direct blocking from the iPhone share flow. When you see an unwanted number or contact, share it to CallDam and create a prefix blocking rule without manually opening the app and rebuilding the rule step by step.

Main features:
• Block unwanted calls by phone-number prefix
• Protect large ranges of related numbers
• Support for up to 1.8 million active protected numbers
• Add exact-number exceptions for numbers you still want to allow
• Pause, resume, edit, or delete rules
• Batch-edit multiple rules before applying changes
• Add rules directly from the iPhone share sheet
• Import and export local JSON backups
• Apply your active block list through iOS Call Blocking & Identification

Private by design:
• No account required
• No ads
• No subscriptions
• No in-app purchases
• No tracking
• No contact access required
• No blocked-number uploads
• Your blocking rules stay on your device

CallDam prepares your active blocking list locally and applies it through Apple’s iOS Call Blocking & Identification system.

Supported prefix-blocking countries and regions:
Russia / Kazakhstan (+7), USA / Canada (+1), Armenia (+374), Belarus (+375), Ukraine (+380), Tajikistan (+992), Azerbaijan (+994), Georgia (+995), Kyrgyzstan (+996), Uzbekistan (+998), France (+33), Spain (+34), Poland (+48), Denmark (+45), Norway (+47), Netherlands (+31), Switzerland (+41), India (+91), Iran (+98), Australia (+61), Singapore (+65), Turkey (+90), South Africa (+27), UAE (+971), Saudi Arabia (+966), and Egypt (+20).

Important:
To block calls, you must enable CallDam manually in iOS Settings:
Settings > Apps > Phone > Call Blocking & Identification.

CallDam does not collect, upload, sell, or share your blocked numbers.
