Start with the contacts saved on your phone
Calls are evaluated locally on the Android device. No crowd-sourced or global caller database is used, and no network request is required to decide whether an incoming call rings. If Android cannot confidently identify a contact, DenyCalls allows the call rather than risking a false block.
Choose who can reach you
Free can block up to 5 saved contacts. Pro adds unlimited saved contacts, individuals, groups, and timed rules.
