Questions

Do I have to pay to try it? No. Download it, use it, and decide later. Nothing is held back until you buy. The Download page has the installers.

Does the license end? No. You pay once, and the key has no end date.

How do I use my key? Paste it into the About tab of the program. After you buy, Polar emails you an Access purchase link, and it sends you a 6-digit code and then shows the key. See The About tab.

Does the key lock the program? No. Nothing is switched off with or without a key, and if the program cannot reach the license server it carries on.

Is tax added? Where the law requires it. Polar, which sells the licenses as the merchant of record, adds sales tax or VAT at checkout and sends your receipt.

Can I get an invoice with our company name? Yes. Tick I'm purchasing as a business at checkout to add the business name and a tax ID.

What is on my card statement? The charge appears as POLAR*graph-modeler.

Where do I find out what counts as commercial? On the License page, which also has the full license text. If you are not sure, write to sales@graphmodeler.com.

What if I am not happy with it? Write to sales@graphmodeler.com within 30 days for your money back. See the Refund Policy.
