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

Set custom filters, allow only trusted contacts, and create an allow list to avoid blocking important calls like those from delivery drivers or family members.

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

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