Default GPT Extension

Privacy Policy

Single Purpose Description

This extension ensures that every time you click the New Chat button on ChatGPT, it automatically opens with your chosen default model. It intercepts page loads and button clicks to append a model query parameter based on your saved preference.

Storage Use Justification

The storage.sync permission is required to save and retrieve the user’s selected default model (e.g., gpt-4o, o4-mini). Using Chrome’s sync storage allows:

  • Persistence: Preferences persist across browser sessions.
  • Sync: If the user is signed in with the same Google account, the choice propagates across devices.

Scripting Justification

The scripting permission enables the extension to programmatically:

  1. Inject and run content.js on ChatGPT pages.
  2. Modify the New Chat button’s href attribute to include the default model.

Host Permission Justification

The extension declares host permissions for https://chatgpt.com/* so it can:

  • Detect when the user is on a ChatGPT page.
  • Redirect or rewrite URLs on ChatGPT domains.

Privacy Policy Details

  • Data Collection: This extension does not collect or transmit any personal or usage data. The only data saved is the user’s chosen model name, stored locally and synced via Chrome’s storage.sync.
  • Third-Party Services: No third-party analytics, advertising, or tracking services are used.
  • Data Sharing: No data is shared with external parties.
  • Security: All operations occur within the browser. No outbound network requests are made by the extension.
  • Contact: For questions, please visit the project repository or contact the developer directly via the extension’s support link.
