Polar Navy's PolarView NS software partly BECAUSE it was not a "subscription" licensed product. My understanding was pay once, and use it forever. It seems, however, that this has changed with the latest release 3.0.1. Per the Polar Navy release notes;
An update on product licensing and availability. We were informed by a data licensor that the product access to PolarView NS must be no less restrictive than access to the data source. Free application with fee-based network data access is not compatible with the licensing requirements.
Product compliance requires us to either provide free data access or implement application licensing as well. Nice though it may be, free data access and free application is clearly not financially feasible.
So, not without some reservations, but also with hope for a more sustainable outlook, PolarView NS will, again, require a subscription to use. PolarView NS subscription will be included, along with data access, as part of either US or UK chart subscription.
We expect the updated version of PolarView to be available for download in the next few days.
It is too bad that they don't disclose which licensed product incorporated into PolarView NS is requiring the subscription, or make that feature a subscription based option.
$19.99 as of today for either US or UK subscription.
Subscription is annual. Users should renew their subscription to continue accessing online services AND using the program. As far as “lock out” is concerned – when shopping at a brick and mortar business, customers are expected to pay for goods and services rendered regardless of whether armed guards are posted at the door
PolarView security measures will be adjusted based on user compliance.
When shopping at brick and mortar business, customers pay for, and leave with a product. If a product price changes, then subsequent
customers pay the increased price.
It woulld seem that the most viable option at this point is to: DON'T UPGRADE BEYOND Version 2.0.7, and to start learning and using OpenCPN.
