Privacy policy

Changent is a Chrome extension that runs an AI agent in your browser side panel to help automate repetitive web workflows. This policy describes how we handle information when you use the extension, our website at getchangent.com, and related services.

Questions or requests: [email protected]

• Chat history is stored locally in your browser unless you delete it.
• We do not write full conversation content to Changent databases for normal agent use, but messages and page context pass through our backend in transit to AI providers.
• When you run the agent, your messages and relevant page context are sent through our backend to third-party AI providers to generate responses.
• We store account information, usage metadata (tokens, cost, model), and billing records on our servers.
• If you submit product feedback, we store your message. A full agent trace is included only when you opt in.

Information you provide

• Account: When you sign in with Google, we receive your email address and display name through our authentication provider (Supabase). The waitlist on our website uses the same sign-in flow.
• Chat and instructions: Messages you send to the agent, including workflow instructions and answers to agent questions.
• Feedback: Text you submit when reporting an issue with an assistant message. You may optionally include a full agent trace for that conversation.

Information collected automatically

• Usage metadata: Conversation ID, model ID, token counts, estimated cost, turn and message indices, and related billing events. We do not include conversation text in routine usage telemetry.
• Local extension data: Conversations, settings, your authentication session token, tab-group mappings, and optional per-site customization scripts are stored in your browser (IndexedDB and Chrome storage).

Information from websites you use

When you direct the agent to work on a page, the extension may read and process information from those pages to complete your request. Depending on the tools used, this can include:

• Page URLs and tab titles
• Page structure (accessibility tree)
• Visible text and form field values
• Screenshots
• Results of JavaScript run in the page context
• Console messages

This data is used to operate the agent and is transmitted to our backend and to AI model providers as part of inference. We access only pages and tabs you interact with through the extension.

Avoid using the agent on pages with passwords, payment details, medical records, or other highly sensitive information unless you accept that such data may be sent to AI providers to fulfill your request.

Our marketing site at getchangent.com does not use analytics cookies or tracking pixels.

• Waitlist: Joining the waitlist signs you in with Google through Supabase. We store your email address and display name even if you never install the extension.
• Sign-in session: After OAuth, Supabase stores a session in your browser so you stay signed in on return visits.
• Fonts: The site loads display fonts from Google Fonts. Your browser sends a request to Google that may include your IP address. Google privacy policy

Changent requests permissions required to automate browser work:

• Host access (<all_urls>): Interact with websites you ask the agent to work on.
• Debugger: Automate pages via the Chrome DevTools Protocol (clicks, typing, scrolling, screenshots).
• Tabs and tab groups: Manage tabs in the agent's tab group and provide tab context to the agent.
• Scripting: Run scripts for agent tools and optional per-site customizations.
• Storage: Save conversations and settings locally.
• Identity: Sign in with Google.
• Notifications: Send OS notifications when the agent needs input or reports a blocker.

• Run the agent and browser automation tools
• Authenticate you and manage usage credits and billing
• Record usage metadata for operations and account limits
• Review feedback you submit, including optional traces when provided
• Maintain and improve the product
• Respond to support requests

We share data with service providers that help us operate Changent:

• Fireworks AI — processes model inference requests. Prompts may include your messages, system context, tool outputs, and page content. Fireworks privacy policy
• Exa — processes web search queries when the agent uses the web search tool. Exa privacy policy
• Supabase — hosts authentication and our application database (profiles, usage telemetry, billing, and feedback). Supabase privacy policy
• Google — provides OAuth sign-in and hosts fonts loaded by our website. Google privacy policy

During agent inference, messages and page context are processed in transit through our backend and forwarded to model providers. We do not write that content to Changent databases as part of normal operation, but providers may retain it under their own policies.

We do not sell your personal information. We may disclose information if required by law or to protect rights, safety, and security.

• Conversations: Stored locally in your browser until you delete them or uninstall the extension.
• Agent requests: Message and page context are transmitted through our backend to generate responses. We do not write full conversation content to Changent databases as part of normal agent operation, but content is processed in transit and may be retained by AI providers.
• Usage metadata: Retained for billing and operations while your account is active and for a reasonable period afterward.
• Account data: Retained while your account exists. You may request deletion (see below).
• Feedback: Retained until resolved or no longer needed for product improvement, unless you request earlier deletion.

Third-party providers may retain data according to their own policies. We select providers with data-handling practices appropriate for this product, but their retention is governed by their terms.

• Delete conversations in the extension at any time.
• Uninstall the extension to remove locally stored data from your browser. This does not delete your account, usage metadata, billing records, or feedback stored on our servers.
• Sign out to end your authenticated session.
• Submit feedback without including an agent trace unless you opt in.
• Email [email protected] to request access to or deletion of account data we hold on our servers.

We use HTTPS for data in transit and industry-standard authentication for accounts. No method of transmission or storage is completely secure; we work to protect your information but cannot guarantee absolute security.

Changent is not directed at children under 13, and we do not knowingly collect personal information from children under 13.

We may update this policy from time to time. We will post the revised version on this page and update the “Last updated” date. Continued use after changes means you accept the updated policy.
