## What is CallNinja?

Stop repeated spam calls that keep the same local or area-code prefix while changing the remaining digits.\n\nCallNinja blocks user-selected number patterns through the iOS CallKit system. Enter a number from a call you personally confirmed as spam. The app shows the resulting pattern and count, and blocks it only after you review and activate it.\n\n[How to use]\n1. Select your country.\n2. Enable the needed extensions from Slot 1 through Slot 10 in Settings.\n3. Enter the number from the confirmed spam call.\n4. Review the displayed pattern and count, then activate blocking.\n\nExample: Enter 323-773-4540\n→ Blocks up to 1,000,000 numbers in the 323-77XX-XXXX pattern\n\n[Blocking criteria]\nCallNinja has no pre-populated or remote spam database and does not automatically classify calls. The user enters only a number from a call they personally confirmed as spam. The final six digits become wildcards, so the selected range may block up to 1,000,000 numbers. Legitimate numbers may exist in that range, so the user must review and choose the range. Any active range can be disabled or deleted at any time. CallNinja blocks phone calls only and does not filter SMS or MMS.\n\n[Key features]\n• Range blocking for repeated spam calls that change their trailing digits\n• Up to 10 ranges and 10 million numbers total\n• Numbers saved in Contacts are not blocked\n• No data collection and no network communication
