The 'Restrict Sharing' option Explained
In Onform, the default sharing permission for any video that is shared to a client/athlete is that the receiving person can re-share that video to another Onform user. However, if the coach wants to prevent the re-sharing of any video within Onform, the coach can enable the 'restrict sharing' option by long pressing a video thumbnail and tapping 'restrict sharing'. A lock icon will be visible on the thumbnail once this is enabled.
Of course if the receiving person really wants to re-share the video, they could screen record it or video it with a second device, but this makes it much more difficult and helps the coach control who sees their videos which may be their protected inellectual property.
