Questions about Pro
How many devices can I use one key on?
Up to 3. Each browser where you paste the key counts as one. To use it on another computer, you can free up a device in the Polar customer portal.
How do I cancel or get a refund?
In the Polar customer portal. Polar is the seller, so refunds are handled by Polar too.
I lost my key.
Sign in to the Polar customer portal with the email address you bought with. You can see your key there and have it reissued.
Does Pro keep working offline?
Yes. Once the key has been checked, Pro stays on for 14 days without a connection. When you are online, the key is checked again once every 24 hours. This check sends only the key, the organization ID, the activation ID, the fixed label “FormCarbon” and the benefit ID. Your profiles and the contents of pages are never sent.
Does a TablePick key unlock FormCarbon Pro?
No. Each product has its own key. FormCarbon needs a FormCarbon key.
Can I get an invoice?
Polar issues the receipt as the seller. For customers in Japan: a qualified invoice (適格請求書) cannot be issued.
What happens if I don’t buy?
When the 14-day trial ends, FormCarbon goes back to the free plan. Your saved profiles are kept, and every free feature keeps working.
