Is the Puffin Cloud Store free?

Puffin Cloud Store is now subscription-based. There is no usage quota and free trial anymore.

In addition to the existing $1/month subscription, two new low-cost prepaid subscriptions are available at $0.25/week and $0.05/day. The exact price is subject to the tax, exchange rate, and Google's pricing policy for each country. These short-term prepaid subscriptions allow users to pay for Puffin only when they need to use Puffin.
