TikTok being "back" in the United States after facing possible bans in the past due to security and data privacy concerns. If there has been a recent announcement regarding the app's return or its status, I recommend checking the latest news from reliable sources to get the most accurate and updated information.

TikTok had been under scrutiny by previous U.S. administrations, and discussions around its future in the U.S. have been ongoing, including potential bans or forced sales to U.S.-based companies. If TikTok has officially returned or been cleared for use, the details would likely be covered in major news outlets.
