## Use Cookie Option

The **Use Cookie** option lets you extract data from private web pages requiring specific access permissions (like login) by utilizing login status or session information stored in your browser during re-extraction, so you can extract data without additional login steps.

Enabling the **\[Use Cookie]** toggle in the Listly extension popup saves the user's temporary information, allowing data re-extraction through Listly without additional login steps during the validity period.

* **Validity Period**: Saved cookies are **valid for about 1 hour** and expire after that time.
* **Usage Timing**: Useful when re-extraction is needed within a short time for pages requiring user permissions like my pages, order history, private forums, etc.
* **When Disabled**: Initial extraction of private pages is possible, but re-extraction may have higher failure probability without saved cookies.

**Important notes when using cookie options**

* Cookie-based login retention status may be limited depending on user's browser environment or site-specific authentication policies.
* Some sites with strict security (e.g., banks, internal systems) may not support cookie authentication or it may expire immediately.
