  Signal actually does optionally offer previews for a handful of services, and they really jump through some hoops to make that safer: https://support.signal.org/hc/en-us/articles/360022474332-Link-Previews https://support.signal.org/hc/en-us/articles/360022474332-Li... The service being previewed doesn't know who you are because Signal acts as a proxy, Signal doesn't know what you previewed on that service because their client deliberately sends overlapping Range requests so that the preview size is rounded.

  Telegram does crawl links sent in non-encrypted messages. Links in secret chats are left alone, though.
