Android custom rom

Hi, I'm new to this subreddit so please be kind. Recently I downloaded a custom rom for my phone thought xda and i was reading the post and saw some people being treated with some images of em having some "hot moments" and sharing them online. I honestly have some things I wish will stay in private and not be shared and I'm a bit afraid that this custom rom has some spyware seeing that when it booted it had some apps that idk where they came from. The name of the rom is ELITE ui culto and basically it gives you galaxy ai features (it actually worked). If someone wants the link to analyze it ask me
