Is there a service (program) for a simple exchange of files, text, clipboard between devices, incl. mobile?

Question

Data exchange

To make it easy to drop the text / file / clipboard in one place and automatically receive it on another device. And then, after receiving, copy / save with simple manipulations.
End-to-end encryption is a must, and a good transfer rate.
In principle, Telegram is very convenient in this (but there is no e2e encryption). Other messengers, clouds and services for downloading files with link exchange are not suitable.

Answer 1

Everything is in the telegram
In general, the Apple ecosystem. In 1 click, you can transfer everything and the shared clipboard
