HOW IT WORKS
Purchase. Receive. Activate.
The checkout provider handles payment and issues the license. Vantage validates the key directly with the provider.
Receive your key
After successful payment, LemonSqueezy provides the receipt and Vantage license key using the checkout email address.
Activate in Vantage
Open Vantage, choose Activate license, paste the key, and name the device. Vantage validates it through the LemonSqueezy License API.
PURCHASE BOUNDARY
Payment stays with the payment provider.
That1Dev’s website does not host a payment form, record full card details, or place your license key into website storage. The desktop app keeps required activation state in operating-system-protected local storage where available.
- No Vantage website account required
- No license key sent to Marketplace or Vantage AI
- No separate activation backend to configure
- Receipts and payment support remain with the checkout provider
ALREADY PURCHASED?
Activate the key inside Vantage.
Install Vantage Office, open the activation screen, and paste the exact key from your receipt. Never post a license key publicly or send it through Marketplace packages.
LICENSE FAQ
Before purchasing.
Can I try Vantage first?
Yes. A new installation includes a three-day trial. When the trial ends, Vantage preserves reasonable viewing and export access while editing requires activation.
Where is my payment information processed?
Checkout and payment information are processed by LemonSqueezy under its own terms and privacy policy. The Vantage website does not receive full payment-card details.
Where do I find the license key?
The key is provided after successful payment and is normally included with the LemonSqueezy order information. Keep the receipt and key private.
What are the device and update limits?
The exact device allowance, update term, support term, renewal status, price, taxes, and refund conditions are displayed at checkout and govern the purchase.
What should I do if activation fails?
Confirm that the key was copied exactly and that the device is online, then contact license support with the order identifier. Do not send full payment-card information.
