What privacy protections apply when using Perplexity AI?

When using Perplexity AI, the privacy protections that apply depend on the product, the account settings, and the data you choose to share. In general, a service like this will process the text you enter, your account details if you sign in, and technical information such as device or usage data to operate the product, improve performance, and maintain security. If you use connected features, such as file uploads, browsing tools, or integrations, the information you provide through those features may also be processed. The most important privacy protection is to understand what you submit. Anything you type into an AI system can potentially be stored, reviewed, or used to improve the service unless the provider states otherwise in its current policy or settings. For that reason, it is wise not to enter sensitive personal data, confidential business material, passwords, or financial information unless you are certain how it is handled. Perplexity AI should also have a privacy policy and terms that explain retention, sharing, and user rights. Those documents usually describe whether data is used for model improvement, whether it is shared with service providers, and how long it is kept. If there are account controls, privacy settings, or options to manage history and data usage, those are the main tools available to users. Because policies can change, the best approach is to review the current privacy policy and any settings shown on the current web page. If contact information is listed there, that is the place to check for questions about specific data handling.
