    1. What is DeepL Translation?

    1-1. Machine translation services became available in Japan from 2020

    DeepL Translation is a machine translation service developed by DeepL, a company based in Germany, in 2017. In 2020, Japanese was added to the supported languages, leading to its widespread use in Japan. The company's predecessor, Linguee, previously offered an online dictionary service. Utilizing high-quality data from the past, DeepL Translation is regarded as providing natural and highly accurate translations compared to other machine translation services.

    1-2. Translatable Languages

    DeepL translation supports 26 languages as of March 2023. It covers languages from major regions around the world, including Western countries, making it sufficient for general business scenarios. Additionally, from 2020 to 2021, 13 new languages, including Greek and Swedish, were added alongside Japanese and Chinese, enhancing convenience with the increase in the number of supported languages.

    2. Benefits and Considerations of Using Machine Translation

    Here, we will introduce the benefits and considerations of using machine translation.

    2-1. Benefits of Using Machine Translation in Business

    ・Cost Reduction
    It is possible to reduce costs because there is no need to outsource translation. Recently, many companies offer machine translation services for free, which leads to a reduction in human costs. Additionally, if you desire higher accuracy translations or more comprehensive services than what is offered in the free version, opting for a paid version may be one of the choices.

    ・Translation can be done immediately as needed
    Machine translation is also noted for its speed compared to human translation. While a human translator can handle approximately 1,500 to 2,500 words a day, machine translation can be completed in a few seconds to a few tens of seconds. The results of the translation can be checked immediately, making it useful for translating urgent documents.

    2-2. Points to Note About Machine Translation

    ・Clarify the subject of the sentence before translating
    When translating from Japanese to a foreign language, it is necessary to clarify the subject of the original sentence before proceeding with the translation. Compared to foreign languages, Japanese often conveys meaning without explicitly stating the subject. On the other hand, translating into a foreign language without clarifying the subject increases the risk of altering the meaning of the sentence. To reduce mistranslations and correction time, let's clarify the subject before translating.

    ・Check if the security is robust
    Depending on the service, free machine translation may not have adequate security. You must be cautious as the data of the translated text may remain on the service provider's server, and there is a risk of data leakage. As a preventive measure, switching to a paid version of the machine translation you are using could be an option. When selecting machine translation for business use, carefully consider which services have high confidentiality.

    3. DeepL Security

    It is important to consider security aspects when implementing.
    There are many automatic translation services available for free on the internet, but most free services do not guarantee confidentiality. DeepL is no exception.

     

    First, there are two types of services offered by DeepL.

    ・DeepL Translation

    ・DeepL Pro

     

    There is the following description about this DeepL translation. (Our company's summary)

     

    "3. Text and Translation – DeepL Translation (Free Version)
    Please enter only the text you wish to transfer to our server when using the translation service. This text submission is necessary for us to provide you with translation and services. We will process your text, documents you upload, and their translations for a limited period for the training and improvement of our neural networks and translation algorithms.

    If you make modifications to the translation proposed by our company, these modifications will also be transferred to our server to verify their accuracy and update the translated text to reflect your changes as necessary.
    Additionally, your modifications will be stored for a certain period for the training and improvement of our translation algorithms.<br/> Please note that our translation services cannot be used for any text containing personal information.

     

    It is stated that the original text and the translated text you entered will be reused by DeepL. It becomes clear that using DeepL translation when translating business documents that contain confidential information poses significant issues.

     

    On the other hand, there is the following description about DeepL Pro. (Our company's summary)

     

    "4. Text and Translation – DeepL Pro
    When using DeepL Pro, the text or documents you submit are not stored permanently and are only temporarily saved to the extent necessary for creating and sending the translation. After you receive the translated text, all submitted text and documents along with their translations will be deleted. If you use DeepL Pro, your text will not be used to improve the quality of our services. For more details, please refer to the terms of use for DeepL Pro.

    Please note that the use of DeepL Pro for texts containing any type of personal data is only permitted if you have entered into a data processing agreement with us (see Section 8.1.3 of the DeepL Pro Terms of Use).

     

    Additionally, there is the following description regarding security. (Our company's summary)

     

    "14. Data Security
    Your connection to our website and our app is protected by encryption technology that complies with the latest standards. The level of protection also depends on the encryption supported by your internet browser or mobile device. You can determine whether individual pages of our website are encrypted and transmitted by looking for a closed lock or key symbol in your browser's status bar. Additionally, we implement appropriate technical and organizational security measures to protect your data from accidental or intentional manipulation, partial or total loss, destruction by third parties, or unauthorized access. Our security measures are continuously improved in line with technological developments."

     

    Communication is encrypted, ensuring confidentiality.
    By using DeepL Pro, as stated in "4. Text and Translation - DeepL Pro" that "after you receive the translated text, all text and documents you sent along with their translations will be deleted," confidentiality is maintained both in the communication path and on the server.

     

    Regarding the privacy policy of DeepL Pro, DeepL has also prepared a separate page on the "EU Data Protection Regulation" (https://www.deepl.com/pro-privacy_info.html).

    "With DeepL Pro, text is stored only in random access memory (RAM) and not in persistent storage. ... Text will not be used for training machine learning models."

     

    As a reiteration of DeepL's privacy policy, it states that by using DeepL Pro, the input text and translated text are not saved or reused.

    In other words, when translating business documents that contain confidential information, the use of DeepL Pro is essential.
