Notification policy
We email all customers 30 days in advance before adding any new sub-processor. You can object during that window — if we can't resolve the concern, you can terminate your subscription with a full pro-rated refund.
To subscribe to sub-processor change notifications even if you're not yet a customer, email security@outerank.com.
