Terms
Last updated October 2026
What you buy
KnockKnock costs $5, paid once, including sales tax. The price shown at checkout is the one that applies.
Your purchase gives you one license code. You can use it on up to 3 Macs, and it includes all future updates.
Who sells it
Dodo Payments is the merchant of record for KnockKnock. It sells you the license, takes your payment, handles sales tax and emails you your license code.
System requirements
Works on MacBooks with M2 or later, or M1 Pro. Check your Mac before you buy: we don't refund purchases made for an unsupported Mac.
Refunds
All sales are final and we don't offer refunds. If Dodo Payments refunds a payment under its buyer terms, or your bank reverses it, your license code is switched off. See the refund policy for details.
Your data
See the privacy page for what we store, who processes it and what the Mac app sends.
Trademarks
KnockKnock is not affiliated with Apple. Mac, MacBook, MacBook Air, MacBook Pro and macOS are trademarks of Apple Inc.
