For more information, see our Privacy Policy.

Third-Party Services

This plugin connects to external AI services when users interact with chat features. No data is sent automatically – transmission only occurs when users explicitly take action.

Data Transmitted

• Chat Messages: User-entered text is sent to the selected AI provider when the user submits a message
• Uploaded Files: File contents are sent to OpenAI when users upload to a project with Vector Store enabled
• System Instructions: Project-configured system prompts are included with chat requests

When Data Is Sent

• On chat message submission (user clicks send or presses Enter)
• On file upload to a project (OpenAI only)
• On file search/retrieval operations (OpenAI only)

API Keys

• Site owners supply their own API keys – this plugin does not provide access to any AI service
• Keys are encrypted using AES-256-CBC and stored locally in the WordPress database
• Keys are never transmitted to chatprojects.com or any third party

Technical Notes

Streaming via WordPress HTTP API:
This plugin uses the WordPress HTTP API (wp_remote_post) for AI provider streaming. For real-time SSE chunk handling, it leverages the http_api_curl action hook to attach a CURLOPT_WRITEFUNCTION callback only when the WordPress HTTP API selects the cURL transport. This preserves WordPress compatibility (proxy settings, transport fallback, and security hooks) while still enabling low-latency streaming.

If cURL is not available, the HTTP API will fall back to other transports and the request will still complete (though streaming callbacks are only available when cURL is the active transport).

PHP Configuration:
SSE streaming requires specific PHP settings (disabled output buffering, compression off) which are set only within the streaming endpoint functions, not globally.
