## Description

**MarsConnect** enables temporary, real-time data sharing between browser clients, devices, and profiles without accounts or cloud syncing. Use its lightweight popup to send or receive clipboard content, session states, application data, links, and custom messages through user-controlled browser connections.

Designed for developers, testers, remote teams, and power users, MarsConnect offers broad webpage compatibility, granular permissions, event-based data coordination, and built-in logging for troubleshooting. Transfers are transient, locally managed, and cleared when the session ends, supporting a privacy-focused browsing workflow with no personal data collection or unnecessary tracking.
