I don’t know what the official situation regarding data collection is in India but at the very least most websites will collect data of some kind. The best way to protect your privacy is using a VPN. Some are even free, but the only free one I would recommend is proton VPN ,otherwise Mullvad is very good and they let you pay for one month at a time. Also install uBlock Origin and ghostery in your browser. Firefox browser is better than chrome or edge. There are other things you can do, but this is fine for most people.
