If you actually value your anonymity, you will not be able to use most popular communication platforms in the coming months. It’s a perfect storm for the outright invasion of privacy in the USA right now.
Learning to code allows you to build and use your own (as well as other less known) tools.

Learn. To. Coed. Code.
Shouldn’t you just, you know, meet your friend as much as possible physically instead of creating app that no one will bother to use thus making communication hard?
