FAQ
Common questions
Does it work on YouTube and Spotify?
Yes — it works on any site that plays audio through HTML5 media. YouTube, Spotify Web, Netflix, Twitch, SoundCloud and more.
How does the Saweria Pro unlock work?
Donate any amount on Saweria and type your email in the message/note field. The server receives the donation via webhook, generates a lifetime key, and emails it to you within seconds. Paste it in the extension to unlock Pro.
Is there a free trial?
Yes — open the extension, scroll to Support & Unlock Pro, expand it and enter your email under the free trial section. You get a 3-day full Pro trial with no payment needed.
Will it keep working after I close the popup?
Yes. The audio processing runs inside the page via an injected Web Audio context. Closing the popup doesn't stop it — it continues until you close or navigate the tab.
I donated but didn't receive my key. What do I do?
Make sure you typed your email in the Saweria message/note field when donating. If you forgot, contact dzulfanDev on Saweria with your email and donation ID — your key will be sent manually.
