Common Questions
How do I receive the app, and what is your refund policy?
Immediately after purchase, Lemon Squeezy emails you a direct download link for the Windows installer and your unique license key. If the app does not run properly on your Windows machine, contact our support within 14 days for a full refund.
How does the Gemini AI integration work?
The desktop app calls the Google Gemini API for translation nuance and tutor replies. Your beta pass includes a prepaid key, so there is nothing to configure — install it and start typing.
Do I need a continuous internet connection?
A continuous internet connection is required to communicate with the Gemini API for natural translation and conversational practice.
What Windows versions are currently supported?
Windows 10 (64-bit) and Windows 11 are officially supported. Each license key can be bound to one Windows device.
Are there any recurring usage fees?
No. The $5 beta pass is a one-time payment for lifetime core access during and after the beta period.
