Editing Telegram (section)

===User Privacy===
Telegram does not sell user data to advertise to its clients, and only stores the data needed to moderate and keep its messaging client "secure and feature-rich" [https://telegram.org/privacy/eu?setln=en Telegram Privacy Policy] .

The messages shared are not end to end encrypted, unless they are Secret Chats (not enabled by default) and these are not stored in their servers. Normal messages are not end to end encrypted, being instead encrypted from the user's device to the servers (client-server encryption). The latter are stored in Telegram's servers and can be shared with authorities, governments and/or accessed by anyone with potential access to the servers. This allows the messaging client to be accessed in multiple platforms on the same account.

This message client is cross-platform, and available in a vast amount of platforms, such as iOS, Android, Windows, macOS and Linux, as well as being available as a web client and other custom clients.
