oeSENC and oeRNC charts can only be used in OpenCPN.
The license of a chart entitles to assign and install it on more than one device running Windows, Linux, macOS, or Android Operating Systems. The most common case is two assignments per license. You can use them simultaneously or you can save a backup to use in case your main device dies.
Once all the allowed assignments of a chart have been consumed, you will need to license the chart again if you want to install it on more devices.
Once you assign a chart to a device, you cannot unassign if you have already requested charts.
You create a "System Name" for your device and the 'o-charts' plugin gets some hardware and software elements to identify this device. If any of these elements changes, your device will be presented as a new one and you will lose one of the allowed assignments.
Your license should survive any OS update, but if you reinstall your OS, you will lose one of the allowed assignments.
Your license will survive to any update of OpenCPN, 'o-charts' plugin or third party programs.
Only really important hardware changes will kill your license. Connecting peripherals will rarely affect your license.
A "System Name" cannot be deleted or moved to a different device, but we can disable the "System Name" of a missing device to avoid future chart assignment mistakes.
The o-charts USB Key dongle counts as a "portable" device, assigning charts to it allows to install the charts in as many devices as you want. However, only in the device where the USB Key Dongle is plugged in, the license will be active and will display the charts.
According to European regulations, oeSENC and oeRNC charts, as digital content, are exempt from the 14 day cooling off period. Once you have requested charts for an order they will work forever, so we cannot cancel the order and refund you. If you have already assigned a chart to a device, but have not requested charts yet, we can still cancel your order and refund you.
Your charts expire after a year from the purchase date. After expiration, you cannot request updates for them any longer. It is not possible to assign an expired chart to any device, even if it still has free assignments.
