NumBuster
The operator lists Office 33, Building 114, Road 383, Block 316, Manama, Kingdom of Bahrain.
What it is
NumBuster identifies unknown callers and helps users screen phone fraud, spam, and unwanted messages. On Android, it can show caller details on the call screen and lets users check numbers from the call log. The iPhone app offers those tools and phone-number blocking. Its homepage also describes an Android anti-spam SMS client, while web-app help covers number checks and free and paid features.
Users can review and rate numbers, contributing information that may help others assess potential threats. The privacy policy says number information comes from registered users’ activity, not a purchased subscriber directory. A free mobile app is available, with LIGHT, SMART, and PRO+ subscription tiers offering varying features. The privacy policy describes measures including encryption, access controls, monitoring, backups, and vulnerability management. People who are not users can submit privacy and deletion requests through supported website mechanisms without installing the app or creating an account. Feature availability can vary by country, operating system, version, device, provider, platform capability, or legal circumstances. The terms say the service is not intended for residents of the European Union, Bahrain, or the United Arab Emirates.
