Pro unlock (not on sale yet)

A one-time Pro unlock for $19 is planned. When it goes on sale:

• It is a single payment for a license key that unlocks the Pro features, including future updates of those features. There is no subscription.
• The sale is made by a merchant of record, which is the seller, collects any sales tax or VAT, and issues the receipt. Its name and terms will be linked here before the first sale. Google is not the seller.
• The price is the same for everyone. There are no discounts, coupons or custom deals.
• Refunds follow the refund policy.
