## DSGVO und Datenschutz
**Gesamteinschätzung:** Yes

**Overall assessment: **

API/SaaS LLM search with a strong privacy promise for the Sonar API, but no on-prem or self-hosting. Perplexity Sonar is provided as an API for web-based answers, research, reasoning, and deep research. Hosting model: SaaS/API; according to the Perplexity FAQ, compute runs on Amazon Web Services in North America. On-prem, local hosting, or private cloud for Sonar are not confirmed as standard offerings in the official sources. Data processing: According to Perplexity, Zero Data Retention applies to the Sonar API; API prompts and responses are not stored and are not used for training. Only billing metadata is collected, without content data. Enterprise: Perplexity states that it does not use Enterprise customer data for training or fine-tuning; according to the Help Center, files uploaded in Enterprise are automatically deleted after seven days, while threads and organizational data remain unless deleted or removal is requested. Integrations/products: Sonar, Sonar Pro, Sonar Reasoning Pro, Sonar Deep Research, Search API, Embeddings, Agent API, and Enterprise features such as SSO, SCIM, audit logs, connector controls, and file retention settings. 


**Conclusion: **

Very well suited for current, source-based LLM answers via API; for strictly regulated EU use, only deploy with contractual and transfer review due to North America hosting.


[Privacy & Security](https://docs.perplexity.ai/docs/resources/privacy-security)

**Overall assessment:** Conditionally to well suited for GDPR compliance for the Sonar API, depending on the contract. 


**Positive** is that Perplexity states a strict Zero Data Retention Policy for the Sonar API: content from API requests is not stored and customer data is not used for model training. According to the API documentation, only necessary billing metrics are collected, such as token count, model used, timestamp, duration, and API key identification; according to Perplexity, this metadata does not contain prompt or response content. In addition, Perplexity mentions SOC 2 Type II, HIPAA Gap Assessment, and CAIQlite in the trust/security context. 


**Negative** is that, according to the FAQ, Perplexity hosts its compute infrastructure via AWS in North America; for EU customers, this means a third-country/transfer assessment is required. No verified information is available in the evaluated sources about a publicly directly reviewed DPA/AVV or SCC document. 



**Server location:** AWS in North America for language models/API according to the Perplexity FAQ. Conclusion: For API-based research and search applications, significantly more attractive from a data protection perspective than many LLM APIs, but for GDPR-compliant EU use, the DPA/AVV, transfer mechanism, subprocessors, and enterprise contract should be reviewed.
