The record

Purpose: Charles is a web proxy and HTTP monitor that runs on your computer and records and displays data sent and received by browsers or other internet applications configured to use it.
Traffic inspection: Charles lets developers view HTTP and SSL/HTTPS requests, responses, headers, cookies, and caching information.
HTTPS debugging: SSL Proxying lets Charles act as a man-in-the-middle for HTTP/SSL communication so users can debug HTTPS session contents.
Network simulation: Bandwidth throttling and added latency simulate slower internet connections.
Formats and protocols: Charles natively supports JSON, JSON-RPC, and SOAP in a simplified tree format, and supports Flash Remoting AMF0 and AMF3.
Request controls: Users can repeat and edit requests and set breakpoints to intercept and edit requests or responses.
Platforms: The desktop application is offered for Windows, macOS, and Linux, and Charles also has an iOS app for capturing traffic on the device.
iOS capabilities: The iOS app captures HTTP and HTTPS traffic, supports SSL Proxying, and can share individual requests or sessions with desktop Charles.
Privacy and data handling: Charles captures traffic only while recording is enabled and stores captured data on the user's computer; the developers say they do not have access to it.
Update telemetry: Charles periodically contacts a developer-controlled server to check for updates, sending operating system and Charles version information that is kept in aggregate without personally identifying information.
Support: The maker directs users to the documentation and invites them to contact support if documentation does not resolve their issue.
License scope: A user license allows use on one computer at a time, with a second computer allowed when the same person uses both installations; site licenses cover a site and multi-site licenses cover multiple sites.
Organization: Charles is developed by XK72, and its EULA identifies XK72 Limited at an Auckland, New Zealand address.
Headquarters: Auckland, New Zealand
