I paid for Pro but it is not active

Restart the app, sign in with the account you bought with and use Restore Subscription in Settings. If that fails, send us your receipt.

If you bought Knowunity Pro but the app still shows the free plan, try these checks.

1. Restart the app

Close Knowunity completely, wait a few seconds and open it again.

2. Check you are on the right account

Pro belongs to the Knowunity account that was signed in when you bought it. Open your profile and check the username. If you have more than one account, sign out and sign in with the account you used at checkout.

3. Restore your subscription

  1. Open your profile and tap the gear icon to open Settings.
  2. In the Subscription section, tap Restore Subscription.
  3. Wait for the confirmation.

This asks the App Store or Google Play to link your purchase to your current account again.

If you bought on the website

For a purchase made while signed in on the website, use that same Knowunity account in the app.

A purchase from the parents page needs to be connected to the child's account through its activation link or QR code. The parent's checkout email does not identify the child's account. See How do I activate Pro for my child?.

Still not working?

If you see The subscription is already in use on another account, the store purchase is linked to a different Knowunity account. Contact support and include:

  • your username or the email address of your account,
  • where you bought Pro (App Store, Google Play or website),
  • a screenshot of the receipt, including the date and amount.

Support can check which account is linked to the purchase.
