📝 About this app

Private Callr allows you to take back your privacy.

Dealing with person-to-person online selling sites involves trusting the other party a bit too much. Ensure your safety by not giving out your real phone number.

Calling toll free numbers can be risky, as they will see your real phone number. They can then call you back over and over, with no regard to Do Not Call lists. Save yourself the hassle, and just make a private phone call with Private Callr.… View full description on the official store →
