Google accounts get 15GB of storage free, shared across Google Drive, Gmail, and Google Photos. For additional storage, you can upgrade to a premium subscription plan as an in-app purchase. Subscriptions start at $1.99/month for 100 GB in the US, and can vary by region.

Storage subscriptions purchased from the app will be charged to your iTunes Account, and automatically renew unless auto-renew is turned off at least 24 hours before the end of the current period. Subscriptions and auto-renewal may be managed by going to iTunes Account Settings after purchase.
