However, your account must already be a member of the private channel/group to access and clone it. Q: How fast is the download speed? Does the computer need to stay on? A: Speed depends on your network and settings. Download speeds typically range from 6–15 MB/s, depending on your account permissions (priority is given to stability). The program must remain running to complete the task, but it supports resuming interrupted downloads; you can continue after restarting. Q: Is the data secure? A: It runs entirely locally. All data (chats, messages, media) is stored in a local folder and is not uploaded to any cloud service.
