A voucher can provide different types of offers, such as:
An invitation from a friend to try training for free
A campaign code offering a discount or special deal
A corporate discount code provided by your employer
You can enter your voucher code in the menu at the top right of the home screen in the app under "Redeem Voucher." Once you've entered the code, the offer or discount will be directly applied to your account.
If you have a campaign code, you can also enter it during the payment process when completing your purchase in the app or on the web. The discount will then be automatically deducted from the total amount.
