Many users want to know if using NumberProxy allows you to use your phone anonymously, and the answer is no. NumberProxy was created to provide user-to-user privacy, meaning that if you call or text someone your primary number is not visible to the person you are communicating with and is not easily traceable. Full details can be found in our Terms of Service and Privacy policy, but these are the basics: Once a number expires or you manually toss it, it’s not easy for us to figure out much about you or your conversations, your associated phone number is removed from our active servers. We do keep backups of our data for 24 hours and should these records be subpoenaed, we will cooperate with law enforcement. NumberProxy is great if you are trying to protect your phone number from other people. If you are trying to protect your phone number or conversations from the police or equivalent, it’s probably best to seek another solution.

I'm assuming that "our data" includes records of who communicated with who?

In other words, once "[y]our data" is deleted (after 24 hours), you have no other record of who (e.g. "a phone number") communicated with who (e.g. "another phone number")?
