Confidentiality Clause for Your Master's Thesis: When & How

If you are writing your master's thesis in collaboration with a company, you will likely encounter the term "confidentiality clause" (Sperrvermerk). This clause restricts who can access your thesis and for how long, protecting sensitive company data from public disclosure. While the concept is straightforward, getting the wording right and understanding the implications for your academic work requires careful attention. This guide explains what a confidentiality clause is, when you need one, and provides a template you can adapt.

What Is a Confidentiality Clause?

A confidentiality clause — known as Sperrvermerk in German — is a formal statement placed at the beginning of your thesis (typically before the table of contents) that restricts access to the document. It specifies that the thesis contains proprietary information from a named company and that it may not be made available to third parties, published, or reproduced without the company's written consent. The restriction period is usually three to five years, after which the thesis becomes publicly accessible through the university library. The clause protects the company's trade secrets, financial data, or strategic information that you may have used in your research.

Wording and Template

The exact wording of a confidentiality clause may vary depending on the company's requirements and your university's guidelines. However, the core elements remain the same: identification of the thesis, the company involved, the scope of the restriction, and the duration. Below is a widely accepted template that you can adapt to your specific situation. Always have both your company mentor and academic supervisor review the final wording before including it in your thesis.

Confidentiality Clause This master's thesis contains confidential information provided by [Company Name]. It may not be made accessible to the public, published, duplicated, or otherwise disclosed — in whole or in part — without the prior written consent of [Company Name] and the author. The thesis is exclusively intended for review by the examiners at [University Name] and the internal use of [Company Name]. This restriction applies for a period of [3/5] years from the date of submission. [City], [Date] [Signature of the Author]

When Is It Needed?

A confidentiality clause is typically required when your thesis involves proprietary company data that is not publicly available. Not every company thesis requires one — the determining factor is whether your research includes information that the company considers a trade secret or competitive advantage. The following situations commonly require a confidentiality clause.

• Your thesis uses internal company data such as financial reports, customer data, or sales figures
• You describe proprietary processes, algorithms, or technologies
• Your research reveals the company's strategic plans or market position
• The company's contract or NDA explicitly requires a confidentiality clause
• Your thesis includes information about unreleased products or services

Conclusion

A confidentiality clause is a necessary formality for many company theses that protects both the company's interests and your academic integrity. Use the template above as a starting point, adapt it to your specific situation, and ensure it is reviewed by all relevant parties. If you are unsure whether your thesis requires one, discuss it with both your company mentor and academic supervisor early in the process.
