Is it normal for Brazilians to turn off notifications on their phones?

Is it normal for Brazilians to turn off notifications on their phones? My bf is from Rio and he has his WhatsApp and instagram notifications off. He says so many ppl leave their notifications off for privacy. In the US this is considered a little shady like you’re trying to hide something. I told him that and he said it’s cultural. What do you guys think? lol this is so childish I know
