My child already has Pro. Can I still use the parents plan?

An activation link cannot be used on an account that already has Pro. Check where the existing Pro was bought before you buy the parents plan, so you do not pay twice.

Updated November 13, 2026

An activation link from the parents plan works only on an account that does not have Pro yet.

What your child sees

If your child opens the link while signed in to an account with Pro, the page says You already have Pro. Nothing is activated, and your parents plan stays unused.

Before you buy

Ask your child whether Pro is already active in their app. If it is, find out how it was bought. See Where did I buy my subscription?

If you have already bought

  1. Check whether your child signed in with the right account. If not, they choose Switch account on the activation page and sign in with the account that should get Pro.
  2. If the right account already has Pro from another purchase, write to our parents team. Tell them the email address you used at checkout and what the activation page shows. See How do I contact the Knowunity parents team?

Do not buy a second parents plan to fix this.

Two subscriptions

A Pro subscription bought in the app keeps running until you cancel it in the App Store or Google Play. Buying the parents plan does not cancel it. See How do I cancel my Knowunity Pro subscription?

Good to know

  • On a family plan, an account that is already part of another family plan cannot join either.
  • For other messages on the activation page, see How do I activate Pro for my child?
