Telguarder AS

Telguarder is a global, community-supported service and mobile application designed to identify and block spam, telemarketing, and fraudulent phone calls. Operating in 44 countries, it utilizes a crowdsourced database of millions of phone numbers to alert users to potentially unwanted calls. Users can search for unknown numbers, view reports and comments from others, and contribute by reporting nuisance numbers themselves. While the service aims to protect users from scams and harassment, its reliance on user-submitted data and access to call logs and contacts raises privacy considerations. The collection of phone numbers, including those from a user's contact list, could potentially be misused if the database is breached. To protect their privacy, individuals should be cautious about the permissions they grant to mobile applications and can opt-out of data collection where possible.
