Over this past year, the Technology department has been
  monitoring the performance of school-issued Chromebooks. We have
  noticed that many apps and extensions downloaded by students are
  slowing down the Chromebooks due to high memory use and tracking.
  Due to this, on June 1, the school will be limiting the types of
  apps and extensions available to download on the school-issued
  Chromebooks to only those that are approved by the school.
