## Cross-Platform Peripheral Integration

Gecit enables users to share a single keyboard and mouse between Windows PCs and Apple silicon Macs. By pushing the pointer off the screen edge, users transition control seamlessly between operating systems. The software supports copying, pasting, and dragging files across devices, provided both machines reside on the same local network.

## Technical Requirements and Compatibility

The software requires Windows 10 version 2004 or later, or Windows 11, alongside macOS 13 or newer. Both systems must be 64-bit architectures. Users can acquire the Windows version via the Microsoft Store for automatic updates, while a standalone executable is available for those who prefer manual installation without store integration.

## Addressing Input Leap Limitations

The developer created Gecit as a direct replacement for Input Leap, which suffered from frequent connection drops. Analysis revealed that macOS memory pressure and unhandled crashes in the Mac client caused these failures. Additionally, specific clipboard image data often triggered crashes on the Windows side, prompting the development of this native alternative.

## QUIC Protocol Architecture

Gecit utilizes the QUIC protocol to manage the connection between the Windows and Mac endpoints. This choice aims to provide a more stable communication channel compared to previous solutions. As a native application on both sides, it maintains a persistent link, ensuring that peripheral input remains responsive throughout the daily workflow.

## Pro Version and Licensing

Gecit Pro is available as a one-time purchase for $9.99, featuring no subscription model. A single license key covers two Macs and can be transferred via the application menu. The Pro version unlocks advanced functionality, specifically the ability to drag and drop files between the connected Windows and Mac devices.

## Launch Pricing and Payments

A launch promotion offers a 50% discount, reducing the price to $4.99 until November 17, 2026. The checkout process automatically applies the LAUNCH50 code. Payment processing and tax compliance, including VAT and sales tax, are managed through the Lemon Squeezy platform to ensure a streamlined transaction experience for all global users.

## Refund and Support Policy

The developer provides a 14-day refund window for Gecit Pro if the software fails to meet user expectations. No justification is required for refund requests. Support inquiries, including bug reports or lost license keys, are handled via email, with a typical response time of two working days for all customer communications.

## Security and Privacy Standards

Gecit provides a comprehensive privacy policy available in both English and Turkish. This document details exactly what data remains on each computer and outlines the procedures for complete software removal. Since the Windows executable is not yet code-signed, users may need to bypass SmartScreen prompts during the initial installation process.
