Our Referral program is available to all users who have set up an OpenDrive account. You can refer others by using your unique referral link. This can be located under Settings > Referral Program (https://www.opendrive.com/settings/referral-program), while you are logged in to your account. When your referred users upgrade their account, you will earn 500 MB of storage space. You can earn up to a total of 20 GB of free space by referring other users!
