Geeks for your information

Quote:Telegram for Windows has received an update that includes new privacy features that provide better control over your data.
 
As part of the latest update, Telegram is introducing a new feature that now allows you to delete groups you created and call history for all sides without leaving a trace.
 
On mobile devices, you can also delete a secret group for both sides. 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.
 
Last year, Telegram was updated with support for group calls and the company is now adding a new feature that will improve the voice chat experience. This update introduces a new feature that will allow you to adjust the volume for individual participants of a voice chat.
 
While in an active voice chat, you can now click on the top menu and adjust the volume  (microphone levels) of individual participants. Administrators can change the microphone levels for everyone.
