At Eyou Acoustics, we stand behind the quality of our professional DSP software, FIR Generator Pro.
Because FIR Generator Pro is a downloadable digital product and the license key is delivered instantly and automatically upon purchase, all sales are considered final once the license key has been activated.
We offer a 14-day refund policy ONLY under the following strict conditions:
a. You have not activated the license key.
b. The software has a critical technical failure that prevents it from functioning on supported operating systems, and our technical support team is unable to resolve the issue within a reasonable timeframe.
If your situation meets the conditions above, please contact our support team at [email protected] with your order number and a detailed description of the issue.
Please note that our payment processor, Paddle.com, handles the actual transaction, and any approved refunds will be credited back to your original payment method within 3-5 business days.
