Heygram is an unofficial version of the telegram messenger that uses the API of telegram and works with internal MTProto Proxies. It allows you to hide chat, group, or any chat of the person you want to use secretly, and only visible it when needed.

Heygram allows you to forward messages without quoting, with editing, or adding a caption to media by using the ""advanced forward"".

If any of your contacts change their profile picture, username, name, or phone number, you will be notified of the change and will be able to see the changes in a special section.
