What Who Called is
Who Called filters unwanted calls using an official telemarketer prefix list and community reports. Its apps are available for Android and iOS, and the website lets people check an unknown number’s reputation and report it. On Android, risky numbers can be blocked before the phone rings, while uncertain numbers can ring with a warning. Reports can be submitted anonymously without an account. An optional SMS shield hides notifications from unwanted messages without storing or transmitting their content. The maker says the apps have no account, ads, or third-party trackers, and that user data is not sold or shared. Blocking rules, settings, and the local call-filter log stay on the device and are removed when the app is uninstalled. Lookups and voluntary reports send information to the service; lookup requests are not stored, and reports are retained for at most 365 days. The maker says its API is hosted in the European Union and traffic is encrypted using HTTPS/TLS. The app is described as open source, with a public source-code repository, and is free.
