About this app

"Darekana Block" is a service that can identify nuisance calls, automatically block incoming calls, automatically identify the caller, and filter SMS.

Easy setup prevents unwanted "nuisance calls" and supports safe and secure calls.

[Darekana Block Functions]

■Identification of unknown numbers

The caller information is automatically displayed by checking against a database of incoming numbers from unknown phone numbers. In addition, if the phone number is considered high risk, an alert mark is displayed. This function is useful for distinguishing important calls such as reservation confirmations and calls from hospitals from nuisance calls such as fraud and sales.

Even when there is no incoming call from an unknown number, the caller information is identified and displayed in the call history. This allows you to immediately determine whether or not you need to call back.

■Automatic nuisance call rejection
Based on information reported by many users, we regularly investigate and analyze special fraud and malicious nuisance calls, and reflect the latest data. High-risk phone numbers, such as "one-ring" calls aiming for callbacks, are registered on the automatic call rejection list and updated regularly.

■ Automatic update of data in the phone number database
By regularly updating the phone number database, the accuracy of the ability to identify incoming calls is maintained.

■ SMS Assistant
When you receive an SMS from an unknown person, it will identify it from keywords and URLs in the message and automatically separate necessary messages from unnecessary messages. It also scans all URLs in the message to check whether it is safe to access. You can also send and receive messages within the app.
