I took another approach when dealing with sharing my contact with others, particularly my phone number.

My contact page contains a QR code for a vCard, but the phone number is end-to-end encrypted and not rendered if the correct key isn't provided. It's only available on my phone for friends to scan in person.

then why even put it on a website?

I like using my personal website as a platform for experiments, this was one of them. Also I can choose to selectively share my phone number with others (using a normal or private tab), which the Android contact app doesn't do.
