It is not possible to directly change the language of your monthly subscription.
However, if you'd like to change the language of your subscription, you can do as follows: first, please cancel your current subscription: How can I cancel my WordDive subscription?
After that, please start a new subscription to another language on our website or through the mobile app.
If you have a fixed-term licence and you have already completed all the courses, please contact our customer support to change the language of your licence. Please, note that there has to be at least one month left in your licence in order to change the language.
