Purchase terms.

What you purchase

PairInk for Windows is a $39 one-time purchase for version 1.x. The license is for one Windows PC at a time and can be transferred when you move to another PC.

This offer is for the Windows license. It does not represent a live iOS or Android store purchase, and no iOS or Android store purchase is included in it.

Trial and activation

The trial lasts seven days and is limited to three active boards. Customers do not need an app account. After purchase, use the license key in your receipt in the Windows app’s License panel to activate PairInk.

An internet connection is needed for initial activation and to refresh Pro access at least every 30 days. PairInk’s drawing boards are stored locally on your devices; local drawing storage is separate from the purchase service.

Transferring to another PC

The license can be transferred through the Windows app’s License panel. The previous offline activation may continue for at most the remainder of its 30-day expiry. After that, use the license on the new PC.

Local work and paired devices

PairInk uses your local Wi-Fi for the shared whiteboard workflow. Your Windows PC runs the sync service and your board content stays in local storage. The iPad experience uses the paired browser workflow described on the product page.
