CallApp Software Ltd.

CallApp is a mobile application that provides caller ID, call blocking, and call recording services to a global user base. Its primary function is to identify unknown callers, with a database reportedly containing over eight billion phone numbers. The application gathers information from public sources and its users' contact lists, enriching this data with details from social media platforms to create more comprehensive caller profiles. While its main users are individuals seeking to block spam and identify unknown numbers, CallApp also offers services for businesses to brand their outgoing calls. The collection and publication of personal phone numbers and associated names, often without the direct consent of the individuals listed, poses significant privacy risks, including potential harassment, stalking, and doxxing. Bad actors could misuse this readily available contact information to target individuals for scams or other malicious activities. To protect their information, individuals should be mindful of the permissions granted to applications and can request to have their number removed from the service's searchable database through an unlisting process on the CallApp website.
