The key is emailed automatically the moment a purchase completes. If it isn’t in your inbox, check spam first — then email support@kott.io with the address you paid with and we’ll re-send it. Nothing is lost; the key exists whether or not the mail reached you.

A desktop license covers up to 5 Macs that you personally use. Enter the same key on each. If you hit the limit because of a machine you no longer own, email us and we’ll clear the old activation.

Only once. The app verifies your key the first time you activate it, then stores a signed license locally and re-checks it on your own Mac from then on. After that it runs fully offline — no account, and your frames never leave the machine.

Connect the controller before launching kott, and make sure no other application has it open — most MIDI devices allow only one connected app at a time. kott is built around the Korg nanoKONTROL2 class of controller; other class-compliant devices generally work but may need mapping by hand. Still stuck? Email us the exact device model.

macOS asks for permission the first time each is used. If you declined the prompt, re-enable kott under System Settings › Privacy & Security › Camera (or Microphone), then restart the app. Both are optional — you can load a video file or still image instead, and audio-reactive modulation simply stays idle without a mic.

The desktop app is sold through Paddle, which acts as the merchant of record and handles invoices and tax — so charges appear from Paddle rather than kott. For refund eligibility, EU/UK withdrawal rights and how to request one, see the refund policy. For anything a policy doesn’t answer, email support@kott.io.

Please don’t use this address for vulnerabilities — send those to security@kott.io and see our responsible-disclosure policy.
