Terms of Service

SightZero provides a website for product information, legal documents, pricing, payments, license delivery, and Windows desktop downloads.

The Windows app installs a free shell first. Premium features unlock only after the app verifies a valid license code, receives a signed entitlement, and downloads the signed premium payload.

License codes are issued after successful payment. Codes must be redeemed inside the official SightZero Windows app Premium section, not in the browser.

A redeemed desktop entitlement may be bound to a specific device or installation profile. Attempts to bypass that binding, replay tokens, tamper with manifests, or clone premium access are prohibited.

The installer may require you to review these terms and the Privacy Policy before installation completes.

The app may check SightZero.Website for signed release metadata, installer updates, and premium payload assets. Premium downloads may be blocked if signature, hash, entitlement, or device checks fail.

Premium eye-tracking features may use the device camera after you explicitly enable them in the app. Camera permission is controlled by your operating system and can be revoked at any time.

SightZero is designed so eye-tracking analysis runs locally on the device. Enabling the feature does not authorize us to upload raw camera video as part of normal operation.

You may not attack the infrastructure, abuse checkout or redeem endpoints, evade rate limits, tamper with desktop security checks, reverse engineer premium delivery controls for redistribution, or use the service unlawfully.

We may suspend or revoke access, block traffic, or invalidate entitlements when abuse, fraud, chargebacks, or security risks are detected.

Paid plans, renewal behavior, and pricing are shown on the website at the time of purchase. Subscription access may end when the paid term ends or when a charge is refunded or revoked.

Support, legal notices, and license-move requests should be sent to the contact address listed on the website.
