We know that artificial intelligence can create, translate and edit all kinds of content. It is also fast, available at any time, and ever friendly.
And it is common knowledge that there should always be a “human in the loop.” But many companies are concerned about something else when it comes to AI, namely: What happens to my data?
Especially in areas such as law, finance or medicine, which deal in highly sensitive information, it is important when using translation or language services that: Confidential information remains confidential.
At Leinhäuser Language Services GmbH we make no bones about it: AI and data protection are not mutually exclusive – on the contrary, in fact. When used correctly, they actually complement each other perfectly.
Choose the right AI tool
AI can translate at lightning speed and often delivers impressive results. But it is worth remembering: Not every AI-powered translation platform is designed to ensure data security and data protection in accordance with European standards (i.e., GDPR).
Uploading content to a public online tool means that it is likely to end up on servers outside the EU, where it will be stored, processed and used to train the model with no prior warning.
This is simply not an option for companies with high security requirements. And it not an option for us at Leinhäuser either.

Data security at Leinhäuser Language Services
Our clear guidelines, trained account managers and secure systems enable us to use AI responsibly. We have an AI policy that governs the use of AI tools and AI models and makes employees aware of the associated risks. It also specifies which content is off-limits for AI tools and AI models: Personal data and confidential information have no place in AI applications. And, of course, we respect customers who prefer to eschew the use of AI altogether.
We use a separate process to ensure that only tested and approved AI tools that guarantee the highest possible level of data security are used. Wherever possible, we prefer systems that comply with GDPR and are hosted in the EU. The central administration of our systems gives us effective control over all relevant files and databases. Data backup is an integral part of our internal processes to prevent data loss and security incidents.
Our employees are given specialized training to use these tools with confidence. We also exceed the mandatory training requirements set out in Article 4 of the EU Artificial Intelligence Act, and are developing specialist AI skills in areas such as copywriting and audio/video localization.
This creates an ecosystem in which technology and data protection work together rather than against each other.
The human-in-command approach
There’s one thing we know for sure: If AI is to be an asset rather than an incalculable risk, it requires comprehensive knowledge of the tool landscape and its possibilities, a sense of responsibility among all those who use AI, and an acknowledgment that a human being must always, always have the final say.
At Leinhäuser, we remain vigilant and are happy to advise on the tools and processes that would be best suited to your content. Our customers can rest assured that every project is handled in an appropriate and well thought-out manner.
The best part: The tools we use offer the option of integrating translation memories, terminology, style guides and other reference documents into the automated workflow, under the watchful eye of trained account managers and linguists who know exactly what their customers need. The outcome therefore complies not only with data security and data protection requirements, but also adheres to customer-specific terminology and tonality.
Discerning use of artificial intelligence
AI technologies are developing rapidly. New systems are emerging, regulations such as the EU AI Act are taking shape, and the market is becoming increasingly diverse.
Our approach, however, remains the same: We use innovation responsibly – and make the most of it.
