Telegram for Windows has received an update that includes new privacy features that provide better control over your data. The company is introducing a new feature that allows you to delete groups you created and call history for all sides without leaving a trace. Since the Telegram servers don’t store your deleted chats, call history or groups, the data will disappear completely once you’ve clicked on the delete button. You can now also report fake groups or channels impersonating famous people or organizations. The update is still rolling out and it will become available for download via the Microsoft Store soon.
