SoundScrub uploads only the extracted audio, never the video, and deletes it right after, so users get a real privacy guarantee that fell out of the technical design rather than a marketing decision. When a property of your architecture happens to answer a fear your users have (privacy, speed, offline use), name it and put it on the page. The most credible selling points are the ones that are simply true because of how the thing is built. Look at your own stack for promises you can already make and are not yet making.
