License Activation

Get a license key

Paid plans are bought on the website: open the pricing page, choose a plan, and pay through the Paddle checkout. Payment is register-first — the checkout asks you to sign in with your email (a one-time code or your password), so the subscription attaches to your account. The license key and receipt are emailed to you automatically.

The Free plan needs no key; it starts on first launch. Activation is for moving to a paid plan.

Enter the key in the app

Open Settings → License, paste your license key (for example OZ-PRO-ABCD-EFGH), and activate. The key is verified against the license server and a signed subscription is stored on the device.

Machine binding

Activation binds the license to the device hardware. The same key can be activated on as many registers as your plan allows, and a tenant admin can revoke a machine remotely.

Your account on the website

Sign in on the website login page with your email and a one-time code or your password. The account page shows your license key, tier, and expiry, and is where you manage your machines.

Offline and grace

Once activated, the signed payload keeps the app working offline through the expiry date plus a grace period, then degrades to the free tier. See Licensing & Plans.
