Short answer
You can delete past conversations from the History screen using the three-dot menu next to a chat or by selecting multiple chats and clicking the Delete button.
Full explanation
AskTuring allows you to permanently delete any conversation from your history. Once deleted, the conversation cannot be recovered. To delete:
Go to the History screen from the left-hand menu.
Find the conversation you want to delete.
Choose one of these methods:
Delete a single conversation: Click the three-dot menu next to the conversation and select Delete, then confirm when prompted.
Delete multiple conversations: Check the box next to each conversation, then click Delete at the bottom of the screen and confirm.
The conversation(s) will be permanently removed from your history.
Tips
Be certain before you confirm, as deletion cannot be undone.
If you just want to review a conversation without keeping it permanently, consider downloading it first.
