PrivacyStar for Android is our most feature rich smartphone application, with over 14 robust features that give you ultimate control over your phone and your privacy.

Features include:

Call & Text Blocking

Call Blocking For Your Smart Phone– Block individual numbers, groups of numbers like entire area codes, private, anonymous or unknown numbers. (see call blocking features for more)

SMS Text Message Blocking – Block SMS text messages. (Report spam text messages!)

Smart Block – Employs crowdsourced data from PrivacyStar users to automatically block the most blocked numbers as determined by the entire user population. (see our list of the top 100 telemarketers and top 100 debt collector phone numbers)

Group Blocking– Block groups of numbers to stop calls from specific area codes,  exchanges, or any group of numbers. Group Blocking works by blocking all incoming calls that start with the same digits that are entered into the Group Blocking list.

Reverse Lookup

Complaint Filing

PrivacyStar allows users to create complaints to the Federal Trade Commission for potential telemarketing, debt collection violations, and SPAM text messages.

Upon the user’s request, PrivacyStar captures detailed information about possible violations including date, time, number and identity. PrivacyStar allows users to easily provide this information to regulatory agencies so they may take action. Learn more about our Do Not Call List compliant filing feature.
