How does the referral programme work?

Share your code with a friend who is new to Knowunity. When they enter it during sign-up, or open your link within 24 hours of signing up, you both get three days of Pro.

What you get

When a friend signs up with your referral code, you both receive three days of Knowunity Pro for free.

Share your code

  1. Open your profile.
  2. Tap the referral or invite option to see your code and share link.
  3. Send the link or the six-character code to your friend.

Enter a code

Codes are entered during sign-up, right after creating the account:

  1. Create a new account.
  2. On the Got a referral code? step, enter the code.
  3. Confirm. Pro is activated on both accounts.

Codes are six characters, are not case-sensitive and never contain the characters 0, O, 1, I or L.

Signed up without the code?

Open your friend's invite link on your phone within 24 hours of creating your account, while signed in to the app. The app adds the invite and you both get the reward. After 24 hours the invite can no longer be added.

Rules

  • The code must be used by a new account on a device that has not used a referral code before.
  • You cannot use your own code.
  • An account that already has Pro gets no extra days. The friend still gets theirs.
  • A code cannot be typed in after sign-up. Within 24 hours, use your friend's invite link instead.

In the United States

Depending on the current offer, US users may receive a gift-card reward instead of Pro days. The reward can be cashed out once it reaches the minimum shown in the app.

If the reward did not arrive, see My referral code did not work or the reward is missing.
