Four clear steps

How DenyCalls Works

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. No account, registration, email address, login, activation code, or app PIN is required.

1. 1. Install DenyCalls

   Get the app from Google Play. No account, registration, email address, login, activation code, or app PIN is required.

2. 2. Check saved contacts

   Keep expected callers in your phone’s contacts. Free can block up to 5 saved contacts.

3. 3. Turn protection on

   Grant the required Android permissions and call-screening role. Check that protection is active.

4. 4. Choose your controls

   Turn protection on or off in Free. Choose Pro through Google Play for groups, timed rules, and local history.
