### External Services

service processes PDF files and provides solutions such as compressing, merging,
flattening PDFs, generating QR codes, and more.

### What data is sent and when:

 * The PDF file or other input data (e.g., user-uploaded content) is sent to the
   external service whenever the user submits a request for processing.
 * Metadata, such as API key and basic request details, may also be sent to verify
   access and ensure proper functionality.

### Why this data is sent:

The data is required to perform the requested operations (e.g., compress a PDF, 
merge files) and return the processed result to the user.

### Where this data is sent:

The data is sent securely to the **Cross Service Solutions API** hosted by XSS (
Cross Service Solutions) Pte Ltd.
