Try it before you decide. Every Pro feature is unlocked for five minutes a day, free, with no account and no card. Audio is the kind of thing you can judge in ten seconds — if you cannot hear the difference, do not buy it.

Fair terms

Nothing that was free becomes paid. Every feature the extension shipped with stays free, permanently. Pro is only ever new capability added on top.

One payment means one payment. No renewal, no expiry, no "your licence has lapsed" a year later. If a future version adds more Pro tools, your licence covers them.

If it does not work, you get your money back. Use "Report a problem" in the extension and say so. No form, no argument.

How activation works

You get a licence key by email after paying. Open the extension's settings, paste the key, press Activate. One key works on up to five browsers.

If our licence server is ever unreachable, the extension keeps Pro working rather than locking you out. It is built to fail in your favour.
