## Smart Call Blocker Description
Block unwanted calls with surgical precision using pattern matching.

Unlike crowd-sourced blockers, Smart Call Blocker lets YOU define exactly which numbers to block using wildcard patterns. Block entire number ranges with a single rule.

FEATURES:
• Pattern matching — Use * as wildcard for any digit (up to 6 wildcards per pattern)
• Block number ranges — e.g., 1900****** blocks 1 million 1900xxxxxx numbers in one rule
• 213 countries — Full E.164 international format support
• Caller ID labels — Identify blocked callers by name
• System-level blocking — Powered by Apple CallKit

PREMIUM:
• Unlimited blocking rules
• Block up to 10 million numbers
• Access to all 213 countries
• 176 pre-built spam templates across 25 countries
• iCloud Sync across all your devices
• Siri Shortcuts and automation
• Priority support

FREE:
• 5 blocking rules
• Block up to 6 million numbers
• Single-country lock (your first rule's country)
• Full pattern matching with wildcards
• Allow list and import/export
• Weekly blocking report

HOW IT WORKS:
1. Create a pattern using digits and * wildcards
2. Preview matching numbers before blocking
3. Enable the extension in Settings > Phone
4. All matching calls are automatically blocked — no app needed

PRIVACY FIRST:
• 100% offline — no data ever leaves your device
• No phone number collection
• No tracking or analytics
• Your rules stay on your device (or your iCloud)
• No account required

PATTERN EXAMPLES:
• 1900****** — blocks 1 million 1900xxxxxx premium-rate numbers in Vietnam
• 02839***** — blocks 100,000 numbers in a Ho Chi Minh City landline range
• 1900555*** — blocks 1000 numbers in a specific US 900 prefix

Smart Call Blocker works at the system level using Apple's CallKit framework, so calls are blocked before your phone ever rings.
