Should I tell my sister?

So I have recently began being active on dating apps. I’m not good at dating and thought the apps would help. They’ve been pretty useless thus far and people are only looking for quicker ways to hook up. So sucks for me. Anyway, I am kind of ashamed that I had to resort to the apps anyway so I don’t want anyone to know. I’m back home and it changed the vicinity of people around so I went and looked and saw my sisters baby dad on there. I don’t know the status of their relationship right now but I screenshotted his profile anyway. I don’t want her to know I’m on dating apps but I don’t know if I should show her that anyway? If they’re not together it shouldn’t matter he hasn’t been the best guy to her anyway but should I show her?
