I have been reading up about HTML5's local database feature and had a few doubts that Google couldn't answer. So I thought I would post them here:

1. I have a MySQL DB on my server. Suppose I want to use the local DB feature, is there some automatic way that the local DB data will be sent back to the server?

2. (just to clarify) browsers that support local DBs use SQLite db no?

3. Is the data stored locally encrypted?
