## DSGVO und Datenschutz
**Gesamteinschätzung:** Conditional

**On-prem / local hosting: indirect / not available**

On-premises, local, or self-hosted deployment is not specified on the website.

**Private Cloud / Data Center: Partially**

The website describes a secure cloud platform with a private network and lists customer-provided encryption keys as an option for enterprise customers. However, a dedicated EU/EEA private cloud or a separate EU data center is not specified.

**EU SaaS / Managed: unclear**

A managed SaaS service is clearly documented, but the website specifies US-based AWS data centers, specifically US East. The website does not specify EU data residency or EU/EEA SaaS operations.

**Hybrid: unclear**

A true hybrid architecture with partly internal/local processing and partly external operation is not specified on the website.

**T&Cs / DPA: Covered**

A Data Privacy Addendum is available on the website and governs the processing of customer data, as well as Standard Contractual Clauses and data protection roles.

**No training: partially**

There is a documented opt-out for product improvement and training. According to the website, this feature is disabled by default for Enterprise, Education, and Team plans purchased through sales. However, for individual users and some multi-user plans purchased directly, training is enabled by default until it is disabled.

**Open Source / Transparency Path: Indirect / Not Available**

Open-source components, open models, or self-hostable open building blocks are not listed on the website. A transparency path exists only indirectly through documentation, privacy, and security materials.

**Data Processing**

The website describes Grammarly as a cloud service on AWS. According to the website, data is stored in the US East region or in US-based AWS data centers. Content may be processed for the purpose of providing the service; for generative AI, information is transmitted to a small number of vetted service providers who, according to the website, are prohibited from training their LLMs on user content. Additionally, there are product improvement and training controls with plan-based default settings.

**Conclusion**

For the EU/EEA, Grammarly cannot be clearly classified as an EU-resident SaaS service based on the website documentation. Positive aspects include the DPA, DPF notices, certifications, and training controls. However, because hosting and storage are specified as being in the U.S. and no EU data residency or on-premises alternative is apparent on the website, its compliance with the GDPR is only **partially** reliable from a European perspective.

From the perspective of users in the EU/EEA, GDPR-compliant use is documented only under certain conditions. Positive aspects include a privacy policy, a DPA/AVV-style agreement, references to GDPR compliance, the EU-U.S. Data Privacy Framework, and opt-out or default-off rules for product training in certain plans. At the same time, the website lists U.S.-based AWS data centers—specifically the U.S. East region—as the hosting location; an EU data residency or EU/EEA server option is not specified on the website. As a result, its use in Europe is viable only with additional contractual and organizational due diligence, rather than as a standard SaaS solution that is clearly and fully EU-resident.

**Positive**

The website includes a privacy policy, a Data Privacy Addendum, information on the GDPR and the EU-US Data Privacy Framework, several security certifications, and a documented option to disable the use of content for product improvement and training. According to the website, product training is disabled by default for Enterprise plans, Business/Pro plans purchased through sales, and Education plans.

**Negative**

The website lists US-based AWS data centers—specifically the US East region—as the storage location. The website does not specify EU data residency, EU/EEA data centers, an on-premises option, or a self-hosting variant. The subprocessor notices also link to a Superhuman subpage rather than to a clearly embedded Grammarly details overview within the Grammarly content being reviewed.

**Server Location**

According to the website, data is hosted in Amazon Web Services data centers in the US East Region or in US-based data centers. EU/EEA server locations or EU data residency are not specified on the website.
