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

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


No on-premise, local, or self-hostable deployment of Perplexity Sonar was found on the website.


**Private Cloud / data center: unclear**


Not specified on the website. No statements were found regarding dedicated customer environments, private cloud, or segregated EU/EEA data centers.


**EU SaaS / Managed: partial**


There is a clearly documented SaaS/API service. However, EU data residency or EU/EEA operation of the service was not specified on the website.


**Hybrid: unclear**


Not specified on the website. No hybrid operating models were described.


**DPA / Data Processing Agreement: unclear**


No DPA or corresponding contractual documentation was found on the website.


**No training: covered**


The website states for the Sonar API a strict zero-data-retention policy and that no customer data is used to train the models.


**Open source / transparency path: partial**


A transparent path is only partially recognizable. The website shows integrations and, for the Agent API, refers to third-party models; however, no open, self-hostable model or openly documented core components of Sonar were found.


**Data processing**


According to the website, the Sonar API processes requests without storing content data and collects only billing-related metadata such as token count, model used, timestamps, duration, and API key identification. External components are also apparent for the platform, such as Stripe for payments and, in the Agent API, third-party models from other providers. No information on EU data residency, subprocessors, or data center locations was found on the website.


**Conclusion**


From an EU/EEA perspective, Perplexity Sonar is primarily interesting because of the documented zero-data-retention policy and the exclusion of training on customer data. However, several key pieces of evidence for a robust GDPR assessment are missing from the website, particularly regarding a DPA, EU data residency, server locations, and subprocessors. Therefore only 'conditionally'.

For Perplexity Sonar, GDPR-compliant use in the EU/EEA is only *conditionally* plausible. Positively documented for the Sonar API are a strict zero-data-retention policy and the exclusion of training with customer data. At the same time, no reliable information can be found on the stated website regarding EU/EEA server locations, EU data residency, data center locations, subprocessors, or a DPA/AVV. In addition, the documentation refers to third-party models and external payment processing for parts of the platform, which creates additional review effort from an EU/EEA perspective.


**Positive**


The website explicitly states that the Sonar API does not store transmitted content data and does not use customer data to train the models. In addition, security attestations such as SOC 2 Type II are mentioned.


**Negative**


The website does not specify an EU/EEA server location, EU data residency, a DPA/AVV, a list of subprocessors, specific data centers, or on-premise/self-hosting options. For the Agent API, the documentation also mentions the use of third-party providers such as OpenAI, Anthropic, Google, and xAI, which can create additional data protection complexity.


**Server location**


Not specified on the website. No specific locations of servers or data centers in the EU/EEA were found on the stated domain.
