Anyone may perform the following activities:

Drop-off
Drop-off (upload) a file for a Centennial user (email verification required).
Pick-up
Pick-up (download) a file dropped off for you.
 
Centennial users: you may login with your username and password and send files to anyone, in or out of the school district.
Non-Centennial users: you cannot log in, but can still send files to Centennial users if you know their email address. Start by clicking the "Drop-off" button.
Centennial users who wish someone outside the school district to send them files, can make it a lot easier for them by logging in and clicking "Request a Drop-off". That saves the other person having to prove who they are. The request created will be valid for 7 days.
 
CSD SendSecure is a service to make it easy for you to move files, including large files up to 20.0 GB, in and out of the school district.
 
How secure is CSD SendSecure?

Files are automatically deleted from CSD SendSecure 14 days after you upload them.
