Block Unknown Callers

To block a few calls, would you really want to upload your contact list to a server? We didn't think so.
To use the majority of caller ID and spam blocking apps, you must share your entire address book. The Privacy Call Blocker is unique. We believe that quiet shouldn't come at the expense of your privacy. 🔒 100% Offline, 0% Data Collection Check our permissions:

We require NO Internet access. This means it is technically impossible for us to send your contacts or call history to any third party. Your private life is kept completely private. Safety Features: 1. No Cloud, No Risk: All blocking logic happens locally on your smartphone. There is no central database and no tracking of your communication habits.
