License & Early Access
Early Access
During the Early Access period, all Pro features are available for free.
No credit card required. Early Access is completely free, billed via Lemon Squeezy. For standard Pro pricing after Early Access ends, see Pricing (opens in a new tab) on the website.
How to Activate
Open the License dialog
In Zentro, open License from the app menu.
Click "Join Pro Early Access"
Zentro opens a secure checkout page in your browser (no charge — it's the $0 Early Access plan). Enter your email there to complete it.
Come back to Zentro
Once the checkout completes, Zentro emails you a confirmation link. Click it, then reopen the License dialog in the app — your status updates to Pro Early Access.
There's no license key to type in — activation is tied to your install automatically once the checkout/confirmation completes.
How Licensing Works
Your license is tied to your email and this machine's installation ID. On activation, Zentro checks your subscription status with the license server and caches a signed entitlement locally, so the app keeps working offline for a while (see Offline Grace Period in Free vs Pro) between refreshes.
The License dialog shows your current status (Free plan / Pro Early Access — with days remaining / Pro unlocked / Needs attention), project limit, masked license key, next refresh date, paid-plan expiry (if any), and offline grace expiry.
Moving to a new device or reinstalling? Go to Settings → License and click Restore license. Since the email already has an active Pro plan, Zentro sends a confirmation link to that email first — click it, and the license activates on the new device.
Managing Your Subscription
The License dialog (opened from the app menu) links to the website for feature comparisons and pricing — there's no in-app "manage subscription" button yet. To cancel or change your plan, use the billing management link from your Lemon Squeezy purchase/receipt email. Cancelling reverts Zentro to the Free tier at the end of the current billing period.
