Licensing & Activation
KestrelSign uses a simple one-time purchase model. No subscriptions, no recurring fees. Buy once, use forever.
Free Trial
KestrelSign includes a 14-day free trial with full functionality. The trial starts automatically when you first launch the application -- no account creation or email address required.
During the trial, you have access to all features with a limited number of signing operations. This gives you enough to test your workflow and confirm KestrelSign works for your use case before purchasing.

Purchasing
You can purchase KestrelSign directly from within the application or from the product page. Payment is processed securely through Stripe. We accept all major credit cards.
After purchase, you will receive a license key by email. Enter this key in KestrelSign's licensing panel to activate your copy.
Activation
Each license key can be activated on up to three machines. This lets you use KestrelSign on your development machines across platforms -- for example, one Windows desktop and one Mac laptop.
Activation requires an internet connection to validate your license key with our server. After activation, KestrelSign periodically validates the license in the background. If the server is unreachable, the application continues to work normally with a grace period.
Managing Activations
If you need to move KestrelSign to a new machine, you can deactivate it from the licensing panel. This frees up the activation slot for use on another device. If you are unable to deactivate (for example, if the machine is no longer accessible), contact support and we can reset your activations.
Updates
Your license includes one year of free updates from the date of purchase. During this period, KestrelSign checks for updates automatically and can download and install them in-app.
After the first year, you can continue using your current version indefinitely. If you want to receive newer updates, you can purchase an update extension.
Refunds
We offer a 30-day money-back guarantee. If KestrelSign does not meet your needs, contact service@robottworks.com within 30 days of purchase for a full refund.
