Landlord entering my rented flat without permission in Hyderabad, what can I do?

I’m renting a flat in Hyderabad, and my landlord keeps entering without any notice or permission. Twice this month, I came back to find him inside, claiming he was checking on things. I feel unsafe and my privacy is being violated. I haven’t broken any terms of the lease agreement. I've told him to stop but he doesn’t listen. What legal action can I take to protect my privacy and ensure he respects our agreement?
