database-per-user is a common pattern with CouchDB. If you need to aggregate data across your users for reporting etc then you can use a server-side replication to create a "master" database which is only accessible to your internal users.

You could also use filtered replication but it is: a) not scalable b) not secure (the whole db would still be accessible to all users)

Couchbase has a different spin on this via "channels" though I'm not sure how it interoperates with PouchDB.

Couchbase Sync Gateway's channels are just slices through the data. The mechanism is internal to the Sync Gateway (you write a JS function that says who can see which channels and which channels a doc belongs to.) Replicating clients don't Need to know about this filtering, so channels work great with all flavors of Couch.
