Privacy by design

We built Comet because a browser is the best way to build a personal and proactive AI assistant that moves at the speed of thought. This raises new questions about data and information sharing.

FAQ’s

These are the most common questions about Comet and your data. Please refer to Comet Privacy Notice and Terms of Service for full context.

How does Comet handle my data?

Comet collects data locally to provide a better browsing experience. Data stored locally includes:

• Browsing Data: URLs, search queries, cookies, open tabs, and site permissions, stored locally on your device and are used to recommend navigational links and power AI features when relevant.

• Technical Data: Device OS, crash logs, and IP, used for security and troubleshooting.

• Add-ons & Extensions: With your permission, passwords, payment methods, profile info, and settings may be saved to your Comet profile. These are stored locally unless synced to the cloud.

Comet is designed with privacy and user control at its core. Our settings give access to clear, granular privacy controls, including the ability to delete browsing/search history, cookies, and cached data at any time. 

You can find out more about how to fine-tune your settings in the Privacy settings available at comet://settings/privacy.

What is a personal search? How does Comet Assistant use my personal data?

Comet Assistant does not personalize searches unless the user asks a question that requires personal context. Personal context is required to perform actions on the user’s behalf, such as “book a restaurant” or “organize my emails”. These capabilities are best used with Comet Assistant, which is the side panel that opens on the right to help you work on the current page. Comet Assistant allows you to ask questions about currently open tabs, search the web, and interact intelligently with websites on your behalf.

What data is transferred between Comet and Perplexity?

Perplexity is the search engine that powers Comet by default. By default, all Comet data is stored on your device only. Comet does not send personal data to Perplexity until a personal search is asked to Comet. When a personal search is asked, Perplexity will use some Comet data, such as the currently open tab and relevant browsing history, to inform how it completes your requested task.

In future versions of Comet, a cloud sync feature will be built-in to Comet to securely sync local data, such as bookmarks and history, with your Perplexity profile. Cloud sync of browsing data will be an opt-in feature, and users will be able to opt out at any time.

Does Comet store my email content or account credentials on specific websites?

Comet may process some local data using Perplexity’s servers to fulfill your queries. This means Comet reads context on the requested page (such as text and email) in order to accomplish the task requested.

Account credentials (like passwords and credit cards) are stored locally on your device’s secure vault, which varies depending on the OS, and never on Perplexity’s servers.

What does Comet do with integration permissions (like accessing Gmail or scheduling)?

For Perplexity searches that relate to your email or schedule, Comet may ask whether you want to grant “Perplexity Connector” elevated integration access, such as integrations to third-party services. Integration access granted to Perplexity is strictly opt-in and users can opt-out at any time. You retain full control over these permissions and may revoke or modify them at any time within Perplexity settings. Data is also only used when relevant and requested by the user.

Does Comet collect my browsing data? What is it used for?

Browsing data may be used when needed to fulfill searches and agentic actions, as well as to provide and improve your Comet experience, but you have the option to delete this data at any time via the privacy settings at comet://settings/privacy.

Your browsing and search data is managed according to the Comet Privacy Notice. Comet does not and will not sell your data.
