Can I change my subscription plan from annual to monthly?
No. If you wish to change to a monthly billing period, you need to terminate your annual subscription first.
You can do so from your DeepL Pro Account, under Plan by clicking on Cancel subscription.
Please note that after requesting the termination of an annual contract, your subscription will remain active until the end of the current annual billing period. You can keep on using your subscription until then. Afterwards, you will be able to sign up for a new subscription with a monthly billing period.
