Thanks ❤️ for asking this question. Yes, exactly the search engine does not share any data except the search query and IP address and nothing else making it really private though we will be adding tor and I2P feature which will also remove the concern of sharing the IP address to the upstream search engine as well. 🙂
Thanks ❤ for trying out our project. Yes, that is something that is being worked on currently. Though some pages do support mobile layout, but others are a work in progress. So they will be worked on soon, probably in the next few releases. 🙂
