We will make this clear to you before the interview or focus group begins, and you will have the opportunity to tell us if you are not happy for the discussion to be recorded.
Byddwn yn egluro hyn ichi cyn i'r grŵp ffocws ddechrau, a chewch y cyfle i ddweud wrthym os nad ydych yn fodlon i ni recordio'r drafodaeth.
