Who owns the data, and where is it stored?

You own the data your app generates through social.plus. Your app identifies each user with its own user ID, so user profiles attach to accounts that already exist in your product. Each social.plus application runs in the US, EU or Singapore region, chosen when you create it. A data export API delivers reports of recent data, and webhooks (in private beta) send events to your server. Stream also lets you choose a region for your app, stores data in that region, and supports data exports and webhooks across its products.
