Unknown Call Blocker

■ Call Filter with Customizable Blocking Conditions "Unknown Call Blocker" is a customizable call filter that allows you to choose exactly which types of incoming calls you want to block. ━━━━━━━━━━━━━━━━━━━━ ■ Block Conditions You Can Choose ━━━━━━━━━━━━━━━━━━━━ ● Block Blacklisted Numbers Block specific numbers you have registered and never want to receive calls from again. ● Block Non-Contacts Block calls from any number not saved in your contacts list. (Contacts permission is only used when this specific option is enabled.) ● Block International Calls Block overseas calls that include a country code (starting with +). ● Block Hidden / Private Numbers Block calls where the caller ID is hidden (Private, Public Phones, etc.). ● Block 050 IP Phones Block IP phone numbers starting with "050". ● Block 0800 Toll-Free Numbers Block numbers starting with "0800". ● Allow Known Caller Names (Toggle ON/OFF) Choose whether to allow calls that display a carrier-provided caller ID name (e.g., "City Hall"). ━━━━━━━━━━━━━━━━━━━━ ■ Guaranteed Call Delivery ━━━━━━━━━━━━━━━━━━━━ ● Emergency Numbers Always Allowed Emergency numbers detected by the network will always be allowed through, regardless of your blocking settings. ━━━━━━━━━━━━━━━━━━━━ ■ Additional Features ━━━━━━━━━━━━━━━━━━━━ ● Block History View a list of when and which numbers were blocked. Supports deleting individual entries or the entire history. ● Block Notifications (Toggle ON/OFF) Choose whether or not to display a notification when a call is blocked. ━━━━━━━━━━━━━━━━━━━━ ■ Privacy ━━━━━━━━━━━━━━━━━━━━ All processing is handled entirely on your device. Your contacts and call history are never sent to external servers. Access to your contacts is requested only when the "Block Non-Contacts" feature is enabled. ━━━━━━━━━━━━━━━━━━━━ ■ Important Notes ━━━━━━━━━━━━━━━━━━━━ • Blocked calls are processed silently without ringing. From the caller's perspective, it will behave the same as a "busy" signal. • This app will only function when it is set as your device's default "Call Screening App".
