'Read' notifications tend to be sent client-side, so it's possible on pretty much every platform. If the official client doesn't support disabling 'read' notifications, look for an open source client. If the official client is open-source, find a trusted fork.
i see thank you
In what context?
I’ve never seen any read notifications on HN.
when you receive a message on communication apps like whatsapp or messenger
One of the reasons I strongly prefer SMS and email is the lack of things like read notifications, typing indicators, etc.
