Smooth Feedback Hunter is made and sold by SFH Digital OÜ, a company registered in Estonia, registry code 17568644, at Abaja küla, Järva vald, Estonia. You can reach us at info@sfhdigital.com.
A perpetual licence to use the Smooth Feedback Hunter audio plug-in. You are buying a licence to use the software, not the software itself. The licence does not expire.
The download is the complete plug-in. Without a licence key it runs in demo mode: everything works, but the audio mutes for about seven seconds every two minutes. Nothing else is held back, so you can evaluate it on your own equipment before paying.
Your licence key is sent by email to the address you pay with, normally within a minute of payment. If it has not arrived within an hour, check your spam folder and then write to us — we will resend it.
If you are a consumer in the European Union, you normally have 14 days to withdraw from a purchase. For digital content that right ends once delivery has begun with your express consent. You give that consent at checkout.
We go further than the law requires. Within 14 days of purchase we will refund you in full if either of the following is true:
You release a licence with DEACTIVATE in the plug-in, or by asking us to release it. We can see from our records whether a licence is active, so there is nothing for you to prove. Write to info@sfhdigital.com and we will process the refund to the original payment method.
A licence that is still active on a computer is in use, and we do not refund it.
Updates within the same major version are included at no extra cost. A future major version may be a paid upgrade; if it is, we will say so clearly before you buy it.
Feedback suppression depends on your room, microphones, speakers and how the system is set up. Any figures we publish come from our own test bench and are described together with the method used. They are not a guarantee of what you will get in your room.
The software is provided as is. To the extent permitted by law, our total liability for any claim relating to the software is limited to what you paid for the licence. Nothing here limits liability that cannot be limited by law, including liability for death, personal injury, or fraud.
If you are a consumer, your statutory rights are not affected by anything in these terms.
If a licence key is shared or resold, we may revoke it. We will contact you first unless the misuse is obvious and ongoing.
We may change these terms for future purchases. The terms that apply to you are the ones published on the day you bought your licence.
These terms are governed by Estonian law. If you are a consumer, you may also rely on the mandatory consumer protection rules of the country where you live. Consumers in the EU can use the European Commission's online dispute resolution platform.
