Concerns Regarding Student Use of "Ogle" app The Whittier Union High School District would like to share a concern with our families about a mobile application (app) called “Ogle”. This “app”, which is readily available, claims to be designed for students to post messages, photographs and videos relating to their schools. Students and others are able to do this anonymously and without censorship. For more information, click here.
