Warning: Contact information being shared

I didn’t share the contact I sent an email with the other person as a CC. FROM MY DESKTOP COMPUTER. I didn’t expect everything I had under that contacts information to be shared with someone else who just happens to have the same contact in their phone. This included home and work addresses home and work phone numbers

Yes he opened the email on his phone and really accidentally clicked on the other persons name and got all this information. He had the other person as a contact but only had their phone number. But when he clicked on the name he was able to see all this other information which he did not have prior. As I said this needs to be fixed. It could be dangerous in all kind of ways

Also any notes you may have

Because on the computer the information was not accessible. Only when opened on the phone

What I meant was that if you and someone else have the same person as a contact.

I didn’t mean if I chose to send someone a contacts phone number
