CodeGuide Chrome Extension - Privacy Policy

Effective date: December 17, 2025

This Privacy Policy describes how the CodeGuide Chrome Extension (the "Extension") collects, uses, and protects your information. The Extension helps you create structured technical documentation for your app ideas, transforming simple prompts into comprehensive AI-ready plans that improve the output quality of AI coding tools like Lovable, v0, Replit, Bolt, and Cursor.

1. Scope

This policy applies to the CodeGuide Chrome Extension. When you use the Extension to generate technical specifications, wireframes, or other documentation, that data is processed by CodeGuide's backend services according to the main CodeGuide Privacy Policy available at codeguide.dev/privacy.

2. What the Extension Does

CodeGuide transforms your plain app briefs into comprehensive, structured plans that AI assistants understand. The Extension generates:

Technical Specifications – Detailed tech stack recommendations, architecture decisions, data models, API endpoints, and implementation guidelines
UI/UX Wireframes – Visual mockups of every screen in your application
App Flow Diagrams – User journey maps and navigation structure
Backend Structure – Database schemas, authentication flows, and server architecture

3. Information We Collect

The Extension is designed to collect only what is necessary to provide its functionality.

Data you provide:

Project ideas and prompts you type into supported AI coding tools
Answers to AI-generated clarifying questions about your project
Your authentication credentials (handled securely via Clerk)

Data stored locally (on your device):

Your selected project ID to maintain context across sessions
Theme preferences (light/dark mode)
Authentication state to keep you logged in

Data we do not collect:

Browsing history outside of supported AI coding platforms
Continuous user activity such as keystrokes or mouse movements
Personal information beyond what you voluntarily provide
Content from websites other than supported platforms

4. Supported Platforms

The Extension only activates on specific AI coding tool websites where its functionality is relevant. Content scripts are injected only on:

Lovable (lovable.dev, lovable.app)
v0 by Vercel (v0.dev, v0.app)
Replit (replit.com)
Bolt (bolt.new)
Cursor (cursor.com)

The Extension follows the principle of least privilege and does not access or monitor any other websites.

5. Permissions and Their Justifications

The Extension requests the following Chrome permissions to deliver its features:

storage

Used to persist user preferences and project data locally. This enables saving your selected project ID, theme preferences, and authentication state so they persist across browser sessions and tabs. No sensitive user data is stored—only project identifiers and preferences.

cookies

Required to authenticate users with the CodeGuide backend service via Clerk. This permission allows reading authentication cookies, maintaining user sessions across browser restarts, and verifying user identity when making API requests.

Host Permission: https://api.codeguide.dev/*

Allows the Extension to communicate with the CodeGuide backend API to send prompts for analysis, create and manage projects, generate technical specifications and documentation, and retrieve saved project data. All API communication is encrypted via HTTPS.

Host Permission: https://app.codeguide.dev/*

Enables seamless authentication flow between the Extension and the CodeGuide web application, including redirecting users to sign in/sign up pages when necessary and accessing account features from within the Extension.

Content Script URL Matches

Content scripts are necessary to detect prompt input fields on supported platforms, display the "Plan" enhancement button near the textarea, show the CodeGuide sidebar for accessing saved projects and documents, and insert enhanced prompts back into the AI tool's input field.

6. How We Use Your Information

User-initiated only: The Extension processes content only when you explicitly click the "Plan" button or interact with the sidebar. It does not monitor pages in the background.
Purpose: Your data is used solely to generate technical knowledge bases for your projects, including specifications, wireframes, flow diagrams, and backend structures.
Network transfers: Project data and prompts are sent to the CodeGuide API endpoint (https://api.codeguide.dev) only when you submit actions such as creating a project or generating documentation.

7. Data Sharing and Transfers

We do not sell or lease your personal information.
Data you submit is shared only with CodeGuide services and essential infrastructure vendors required to operate those services.
We may disclose data if required by law or if necessary to protect our rights, enforce this policy, or respond to legal process.

8. Data Retention and Control

Local data remains in chrome.storage.local until you clear it through browser controls or by removing the Extension.
Project data sent to CodeGuide is retained according to your CodeGuide account settings. You can delete projects in the CodeGuide app or request deletion via support.
After six months of inactivity, older projects may be archived, but you can request reactivation if needed.

9. Security

We use industry-standard practices to protect your data. Authentication is handled securely via Clerk, and all network communication uses HTTPS encryption. Your authentication state is stored locally in chrome.storage and transmitted only to authenticate requests that you initiate.

10. Children's Privacy

The Extension is not directed to anyone under 13. We do not knowingly collect information from children. If you believe a child has provided us personal data, contact us so we can remove it.

11. Your Choices and Rights

You can opt not to use the Extension's features at any time.
You may clear local data or remove the Extension at any time.
You can manage or delete your projects in the CodeGuide app and contact support to exercise additional rights available in your jurisdiction.

12. Changes to This Policy

We may update this Privacy Policy to address evolving legal or business requirements. Changes take effect when posted under the "Effective Date" stated above. Continued use of the Extension after an update indicates acceptance of the revised terms.
