Stellar AI Editor Chrome Extension - Privacy Policy

Last Updated: 2025-12-28

Your privacy is important to us. At Stellar App LLC ("Stellar," "we," "our," or "us"), we are committed to respecting your privacy and protecting any information we may collect through the Stellar AI Editor Chrome Extension.

1. Overview

The Stellar AI Editor Chrome Extension is a tool that allows you to edit and modify web pages for A/B testing purposes. This Privacy Policy explains what data the extension collects, how we use it, and how we protect it.

2. Data Collection and Use

The extension collects the following types of data to provide its functionality:

2.1 Authentication Information

  • Authentication Tokens: The extension stores your authentication token locally in Chrome's storage to maintain your login session. This token is used to authenticate API requests to our servers.
  • User ID: Your user ID is stored locally to associate your editing sessions with your account.
  • API Keys: The extension detects and stores your Stellar project API key from pages where the Stellar snippet is installed. This is used to identify which project you're working on.

2.2 Location Data

  • Page URLs: The extension stores the URL of pages where you activate the editor. This is necessary to reopen the editor on the correct page and to associate modifications with specific pages.
  • IP Address: When you make API requests to our servers, your IP address is automatically included in the request headers. We use this for security, fraud prevention, and service improvement purposes.

2.3 Web History and Page Content

  • Page HTML: When you use the AI Editor, the extension reads the HTML structure of the page you're editing. This is sent to our AI service to understand the page structure and generate appropriate modifications.
  • Page Text: Visible text content from the page is collected to help the AI understand context and generate relevant changes.
  • Screenshots: When you use the "draw mode" feature, the extension captures screenshots of the visible page area. These screenshots are sent to our AI service to understand what areas you want to modify.
  • Uploaded Images: If you upload images as design references, these images are sent to our servers for processing by the AI service.

2.4 User Activity

  • Element Selection: When you select elements on a page using the extension's selection mode, information about those elements (selectors, tag names, text content) is collected to understand what you want to modify.
  • Drawing Activity: When you draw on the page to highlight areas, the extension tracks the coordinates of your drawing to identify relevant page elements.
  • Editor Interactions: Your interactions with the editor interface (chat messages, modifications applied, save actions) are logged to improve the service and provide support.

2.5 Experiment and Variant Data

  • Experiment IDs and Variant IDs: The extension stores which experiment and variant you're currently editing. This is necessary to save your modifications to the correct variant.
  • Modifications: When you save changes, the modifications you've made (HTML changes, CSS styles, JavaScript code) are sent to our servers and stored as part of your variant configuration.

3. How We Use Your Data

We use the collected data for the following purposes:

  • Providing the Service: To enable the AI Editor functionality, process your editing requests, and save your modifications.
  • AI Processing: To generate code modifications based on your natural language descriptions, selected elements, or drawn annotations.
  • Service Improvement: To improve the accuracy and functionality of the AI Editor through analysis of usage patterns.
  • Security and Fraud Prevention: To detect and prevent unauthorized access, abuse, or fraudulent activity.
  • Support: To provide customer support and respond to your inquiries.

4. Data Storage and Security

Local Storage: Authentication tokens, user IDs, API keys, and session data are stored locally in Chrome's extension storage. This data remains on your device and is not accessible to other websites.

Server Storage: Page content, screenshots, uploaded images, modifications, and chat history are sent to and stored on our secure servers hosted by Amazon Web Services (AWS), located in the United States. AWS is ISO 27001, SOC 2, and GDPR compliant.

Data Encryption: All data transmitted between the extension and our servers is encrypted using TLS 1.2+. Data at rest is encrypted using AES-256.

5. Data Sharing and Disclosure

We do not sell your personal data or share it with third parties for marketing purposes. We may share data only in the following circumstances:

  • AI Service Providers: We use third-party AI services to process your editing requests. Page content, screenshots, and your instructions are shared with these providers under strict data protection agreements.
  • Legal Requirements: When required by law enforcement, legal requests, or regulatory obligations.
  • Security: To prevent fraud or security threats.

6. Data Retention

  • Local Storage: Data stored locally in the extension remains on your device until you uninstall the extension or clear Chrome's extension storage.
  • Server Data: Modifications and experiment data are retained according to your account settings and our main Privacy Policy. Screenshots and uploaded images used for AI processing may be retained for up to 30 days for service improvement purposes.

7. Your Rights and Choices

You have the following rights regarding your data:

  • Access: You can view your stored data through the extension's interface or by requesting it from us.
  • Deletion: You can clear local storage by uninstalling the extension. You can request deletion of server-stored data by contacting us.
  • Control: You control when the extension is active and what data is sent to our servers through your use of the extension.
  • Opt-out: You can stop using the extension at any time by disabling or uninstalling it.

8. Permissions Explanation

The extension requires the following Chrome permissions to function:

  • activeTab: Allows the extension to access the currently active tab when you explicitly activate the editor. This is necessary to read page content and apply modifications.
  • storage: Allows the extension to store your authentication token, user preferences, and session data locally on your device.
  • tabs: Allows the extension to identify the active tab and capture screenshots when you use the draw mode feature.
  • Host Permissions: The extension can access any website you visit because A/B testing can be performed on any website. The extension only activates when you explicitly trigger it or when you navigate to a page with specific URL parameters from our dashboard.

9. Children's Privacy

Our extension is not intended for users under the age of 13. We do not knowingly collect personal information from children under 13. If you believe we have collected information from a child under 13, please contact us immediately.

10. Changes to This Privacy Policy

We may update this Privacy Policy periodically to reflect changes in our practices or legal requirements. We will notify users of significant updates via email or through the extension interface.

Your continued use of the extension after any changes indicates your acceptance of the updated policy.
