Perplexity Privacy Review
Category: Search Engine | Privacy Score: 45/100 (Below Average) | Open Source: Yes | Independently Audited: No/Unknown
Perplexity is a search engine tool that we have evaluated across multiple privacy dimensions including data collection practices, encryption implementation, transparency, business model alignment with user privacy, jurisdiction and legal framework, third-party dependencies, and historical track record. This comprehensive review provides the information you need to make an informed decision about whether Perplexity meets your privacy requirements.
Privacy Score Breakdown
Our overall privacy score of 45/100 for Perplexity is derived from several weighted factors. Data collection practices account for 25% of the score — Perplexity collects extensive data that goes well beyond what is necessary for the service to function, raising significant privacy concerns.
Encryption and security account for 20% of the score — encryption coverage is incomplete or uses weak protocols that do not adequately protect user data.
Transparency accounts for 15% — being open source allows independent verification of privacy claims and security practices, which significantly strengthens trust. We are not aware of independent security audits for this tool, which limits our ability to verify its security claims.
Business model alignment accounts for 15% — the business model relies heavily on advertising or data monetization, creating fundamental conflicts with user privacy interests.
Jurisdiction and legal framework account for 10% — the legal environment in which Perplexity operates affects the level of government access to user data and the strength of legal protections for user privacy. Third-party dependencies account for 10% — the use of external services for analytics, crash reporting, or infrastructure can introduce additional data collection points. Historical track record accounts for 5% — past incidents, breaches, and responses to privacy challenges inform our assessment of the developer's commitment to privacy.
Features and Functionality
As a search engine tool, Perplexity provides functionality that serves its functional purpose but comes with significant privacy costs that users should carefully weigh against the convenience provided. When evaluating Perplexity for your needs, consider not just its features but how those features are implemented from a privacy perspective. A feature that requires sending data to external servers, for example, has different privacy implications than one that processes data locally.
Comparison With Alternatives
In the search engine category, Perplexity is not recommended for privacy-conscious users. Multiple alternatives in this category offer significantly better privacy protection with comparable functionality.
Configuration Recommendations
To maximize your privacy when using Perplexity, we recommend the following configuration steps. Review and adjust all privacy-related settings, opting out of optional data collection, telemetry, and analytics wherever possible. Disable features you do not need that may collect additional data. Review and minimize permissions granted to the application. Check for and configure any encryption options available. Disable automatic update checking if you prefer to update manually (though keep the tool updated for security). Review third-party integrations and disable any you do not actively use. Consider network-level protections such as DNS filtering and VPN usage to complement the tool's privacy features.
Who Should Use Perplexity
We do not recommend Perplexity for privacy-conscious users. If you must use it due to specific requirements, take all available steps to minimize data exposure and supplement with other privacy tools.
Verdict
With a privacy score of 45/100, Perplexity earns a Below Average rating in our search engine category assessment. This tool has significant privacy concerns that users should carefully consider before adopting it. As always, no single tool provides complete privacy protection — we recommend a layered approach combining multiple privacy-enhancing technologies to build a comprehensive defense against surveillance and data collection.
