Admob policy needed

hi guys, my app is just a basic one as does not collect any information regarding the users etc… the only thing i have on is admob. do i need to get a privacy policy on the app or just leave it without ?

thank you ive sorted it now :slight_smile: the only thing im having problem with is showing the ads lol ive put the app id in the property section and used events to load the advert and show once loaded and added my ad id, but yet the ad wont show on my android device, and my admob account is activated with ads showing
