What is the duration of a DeepL Pro subscription?
The billing period or, in other words, the contract duration of a DeepL Pro subscription depends on the type of plan you select.
The DeepL API Pro subscription only offers monthly payment plans.
The minimum duration of any plan is one month (which is also one billing period), starting on the day you sign up.
The billing period for all annual plans is one year.
You can always check the contract duration of your subscription directly in your DeepL account, under Plan.
