Kaspersky Who Calls databases

Kaspersky Who Calls checks phone numbers using four types of databases:

  • Online databases of phone numbers that have been reported by users as spam
  • Local list of spam phone numbers added by you in the app
  • Online databases of organizations' phone numbers
  • Offline databases of phone numbers on your device (available in the Premium version)

The app displays information for the phone numbers found in the databases.

Spam labels are based on community feedback only and should not be considered a verdict provided by Kaspersky.

Even though you grant the app access to your Contacts, the app doesn't store the information about your calls and contacts. We don't download your personal data or make it publicly accessible or searchable.
