Official piSun Desktop Distribution

Five desktops. The piSun suite in every package.

Student, University, School Admin, Business, and Patron Desktop packages are distributed directly through piSun-controlled sites. Each installer contains piSun Scribe, piSun Grid, piSun Horizon, and piSun SafeSurf.

piSun Technologies

Biometric authentication is the sign-in

The installed desktops do not use a conventional username/password login. PSOP biometric authorization activates the Patron session. Protected actions remain capability-controlled, and the desktop never becomes a second identity authority.

piSun Device Access · software download

Windows, macOS, and Linux Access Point software

Download and use the piSun Device Access app for website, application, and Access Point authorization without a $20 Device Protection charge. A University, School, or Business can grant DEVICE LOGIN access to multiple enrolled students or employees for the same computer. The Patron approves from their piSun phone; the desktop receives a short-lived authorization, not the Patron biometric or stored legacy password.

Additional piSun device provisioning remains a separate $2.99 one-time entitlement after the first device. Device Protection is optional and costs $20.00 per protected device; that fee activates the stronger device-control / protected-login layer and is not the price of this app download.

School surfing policy acceptance

For Student Desktop and School Admin Desktop users, the school surfing policy follows the Patron, not the ownership of the computer. Horizon and SafeSurf remain inactive until that Patron accepts the applicable school policy. This applies on a personal desktop and on a school-owned activated endpoint. After acceptance, Horizon and SafeSurf activate only within the Patron's biometric PSOP session.
