So I wanted to ask if I can restore for example 1 month old deleted whatsapp conversation? I didn't have my backup on and I don't have icloud backup as well. Please help me!
I don't use the app so I don't know. Having said that, you can try the developer's support site for answers while awaiting a response here from someone who may know the answer to your inquiry.
unfortunately you cant do that
Unless you've back up on Icloud or at least check an option for monthly on whats app setting
otherwise only the most recent backup will be restored by whats app
