    11. 9.9.2

      In case DeepL is not able to debit the due payment for payments made by credit card or SEPA direct debit, DeepL will ask the Customer to update the agreed payment method or to provide a new payment method and will inform the Customer of the impending blocking. In case the debit continues to fail after the notification, DeepL is entitled to block access to the Products. After the blocking, DeepL will send another request to the Customer to provide a new payment method in order to restore access.

    12. 9.9.3

      In case and to the extent that the Customer, in accordance with the applicable law, is obliged to withhold a certain amount related to taxes, duties, levies or similar (hereinafter referred to as the "Withholding Tax") from payment to DeepL and remit to the respective tax authorities, the amount payable by the Customer to DeepL will be increased by the amount due for the said Withholding Tax. Consequently, in each case, DeepL shall obtain from the Customer an amount corresponding to the amount the Customer would have had to pay in case such Withholding Tax is not applied. The Customer is obliged to withhold the Withholding Tax in the appropriate amount and in accordance with the requirements of the applicable law and to pay the said amount to the competent tax authorities. The Customer is obliged to provide DeepL with proof related to the proper withholding and corresponding payment of the due Withholding Tax. DeepL will reasonably cooperate with the Customer in order to determine whether the said deduction or withholding of Withholding Tax from the service provided by DeepL is or was required. If this is the case, to the extent permitted by law, DeepL will cooperate with the Customer in order to reduce the applicable Withholding Taxes and to assign to the Customer any claim for repayment of the Withholding Tax (if applicable).

    The translated text.

    The DeepL API is designed to translate at least 600 characters per minute and per Customer; exceeding use may be limited, and Customers may encounter a 429 “Too Many Requests” error message, as described in the documentation.

    For document translations, a minimum of 50,000 characters per document is charged at each time.

    Applications using the API should implement a mechanism to handle such responses accordingly and, if appropriate, to try again later. A mechanism increasing the delay for another request exponentially is recommended.

  2. 2DeepL Pro Translator

    The DeepL Pro Translator offers a service accessible by Customer using their DeepL Pro access credentials. Access can be via a website or Microsoft Windows or MacOS application. The service allows to input texts and receive their machine translations. As the DeepL Pro Translator uses the DeepL API for translating, it supports the set of source and target languages as described in Section 1.

    Within DeepL Pro Translator, Customer's texts and their translations are stored only as long as necessary to create the translation and return it to Customer (as described in Section 3.1.2 and 3.1.3 of the Terms and Conditions.

    DeepL Pro Translator can process translation requests more slowly or temporarily suspend the access to the Products on a case-by-case basis if the length of the entered texts significantly exceeds the normal and reasonable use (starter: 2 million characters per month, Advanced: 5 million characters per month, Ultimate: 10 million characters per month) and therefore the availability of the services to all Customers of DeepL is affected.

    In addition, browsers, their Javascript execution environment, and the HTTP transmission techniques used impose technical limits. The DeepL Pro Translator will try to notify the user about exceeding these limits and warn about possible performance issues.

    The DeepL Pro Translator allows Customer to translate whole documents. Ability to translate documents is subject to the ability of DeepL Pro to correctly read and translate the documents, which can't be guaranteed.
