Call Guardian
Call Blocker

Call Guardian is an advanced call-blocking tool that protects your privacy and gives you peace of mind. It automatically silences, rejects or diverts unwanted calls, including spam, unknown numbers and unauthorised contacts.

Set up custom filters, allow only trusted contacts and create a whitelist to avoid blocking important calls, such as those from delivery drivers or family members.

It includes STIR/SHAKEN verification to identify legitimate calls and prevent impersonation. All processing takes place on your device, without collecting or sending your data.

Enjoy statistics, optional notifications, a history of blocked calls and a simple, effective interface. You can also support the project with small donations.
