PrivacyStar, available for BlackBerry and Android, is an app that gives you complete control of your phone by providing the ability to stop unwanted or unknown calls, and a Caller ID feature that is traditionally found only on landlines. From your call log you can add any number to your PrivacyList, which will stop that caller from calling you again. Users have the ability to block a single number or entire area codes. PrivacyStar also counts the number of blocked calls so users can see the benefit of the service. The Do Not Disturb feature has the ability to block groups of people, anonymous or restricted callers.

PrivacyStar has over 1 million unique blocked number - blocking 5 million total. Its unique set of features allows people to live a more productive lifestyle by eliminating unwanted calls and identifying the name of a caller even if they are not in the address book. In a world where people are abandoning landlines and living solely on smartphones, PrivacyStar provides the ultimate control of mobile devices.

Over 200 million people have registered on the national Do Not Call Registry, but many still receive calls from telemarketers. An increasing issue revolves around debt collection practices with debt collectors violating federal and state laws attempting to collect debts from consumers. PrivacyStar provides the ability to report Do Not Call Registry and Fair Debt Collection Practices Act violations directly to the FTC - users have reported over 130,000 complaints.

The SmartBlock feature is a database of the most blocked numbers by PrivacyStar users. This unique function automatically blocks these numbers from calling all its users.

For Android, PrivacyStar offers text blocking to eliminate mass SMS marketing campaigns or just senders that users never want to hear from again.

PrivacyStar also offers a Caller ID feature that until now has only been found on landlines - number and name associated. This unique feature allows users to screen their cell phone calls without having to wait for the voice message.
