KleenMicThe product
KleenMic is a downloadable Mac app that reduces microphone background noise and provides speaker echo control. Compatibility requirements are shown on the product page. Results depend on your microphone, environment, and calling app.
Trial and pricing
KleenMic offers a 72-hour trial, with no payment card or account required. An internet connection is needed to start or reopen the trial. The trial period does not restart when the app is reinstalled.
The advertised lifetime activation costs $20 USD as a one-time purchase. Applicable taxes and the final total are shown at checkout before payment. There is no recurring subscription for this lifetime purchase.
Activation and offline access
A purchase key activates one Mac at a time. Activation and license transfers require an internet connection. Keep your purchase receipt and activation key available for support.
Lifetime describes the one-time activation purchase. Periodic online verification is required: a current activated license can work offline for up to 30 days before reconnecting. If access expires, audio processing is disabled while microphone passthrough remains available.
Payment, delivery, and support
The checkout identifies your payment provider and purchase conditions before you confirm payment. Keep the receipt from that provider. If a purchase key is missing or activation fails, contact support@kleenmic.app with your order reference.
For a purchase problem or refund request, see Refunds and purchase support. The conditions shown with your order and applicable consumer rights govern refund eligibility.
