"NOSTR AND PERSONAL INFORMATION"
"One of the differences between nostr and other apps such as tiktok is that personal information such as phone numbers and email address are not asked by nostr whilst apps such as tiktok, twitter and Facebook demand this. Apps such as session don't ask for personal information which is a consequence and phone calls can be done without a phone number being given. This is a result of WhatsApp letting users call other users without sim card charges."
