    No catch! It’s simple: you invite friends and, in exchange, you get to experience a few months of premium Octeract Engine for free.
  • How long will my free trial last?
    3 months
  • When will I know if I have qualified for the offer? 
    As soon as your friend(s) join an Octeract subscription plan, we will validate their email address/es and upgrade your tier accordingly, for free!
  • Is the referral program available to Academics?
  • How many friends can I invite?
    For now, you may invite up to 4 friends.
  • Do my friends need to join a premium tier in order for me to qualify for the offer?
    Nope! Your friends can join any tier including Community, which is 100% free for them!
  • I want to invite more friends because I don’t know how many will sign up and validate the subscription with their email. Can I do this by filling in two forms?
    Yes, you are welcome to do this.
  • What happens when my free upgrade ends after 3 months?
    You can choose to either downgrade to your previous subscription plan or continue with your upgraded subscription and be billed accordingly. The choice is completely yours.
