My Klangio Subscription is not Active

If you’ve just upgraded to our Pro Subscription for any of the Klangio apps and realize that you still can’t access your premium features, then you’ve come to the right place. In this guide, I will show you how to fix this.

Confirm your Purchase #

First check if the purchase was successful, by checking your Mail Inbox. Here you should find a receipt that your payment was received, and your subscription is now active.

Log out and Log in #

Occasionally, the Klangio Account struggles to register the changes. To fix this, simply log out and log back into your account.

Check your Account status #

You can check if the subscription is activated with the Klangio account you are logged into by:

  1. Navigate to your songbook.
  2. Open up the menu in the top right corner.
  3. Click on “Account Info”
  4. See if your subscription is mentioned in this section.

If your subscription is not mentioned, it might also be that you are not logged into the account for which you have purchased the subscription. Please check the receipt you have received via mail to make sure that your purchase was successful, and you are using the correct Account and email address.

Make sure you are using the right Klangio App #

It can happen that you accidentally navigated to a Klangio App for which is different from the Klangio Subscription that you bought. In this case, try this:

  1. Confirm which Klangio Subscription you have bought (i.e. Piano2Notes Pro, Scan2Notes Pro, Klangio Universe) with the receipt you received via mail after your purchase. Also make sure that there are no typos in the email for which you have purchased the subscription.
  2. Navigate to klang.io and click on the “Products” section at the top of your screen. Select the app for which you have purchased a subscription.
  3. Click on the “Login” button in the top right corner or open up the menu in the top right corner and click on “Login” if you are using your smartphone.
  4. Make sure you are using the email address of the Klangio Account, which you have also used when purchasing your subscription.

Contact Us! #

In case, you still don’t have access to your premium features or your account, then please wait for one hour and try it again. If even this doesn’t help, please reach out to us via our contact form and let our chatbot know that you have already tried all these steps and would like to talk to one of our support team members.

I hope that explains how to activate your Klangio Subscription, if it doesn’t do so automatically.

Frequently Asked Questions #

I have an issue with my subscription purchased via MuseHub. What can I do?

Where do I enter my license key from Paddle?

To use your subscription after purchasing it via our website, no license key needs to be entered. Simply go back to the website of the product you purchased (for example, https://klang.io/piano2notes ) and log into your account. (Please be sure to use the same login method (for example, Google Login) as when first signing up to access the correct account). Your subscription will be up and running, and you can start transcribing your music.

For a single transcription, please look for an email from Klangio with the link to your full transcription. You can also find the link to your full transcription in the confirmation email from our reseller Paddle. The link should look like this: https://studio.klang.io/file?id=(followed by some numbers and letters) (this example is for our Transcription Studio)

How to restore in-app purchases/ My subscription on my mobile app is gone?

If your subscription was purchased with the same Play Store/App Store account that you are currently using, then purchases can be restored. Simply log into your Klangio account in our app and click on the little ticket symbol in the top right corner. You can then scroll all the way down to find the option “restore purchases.” Follow the instructions on your screen to add your subscription to your account.
