Google Gears is an open source browser extension that enables web applications to provide offline functionality using JavaScript APIs. Due to the concern about internet security, building web application which store and serve sensitive information locally on users’ own computers are very useful.

• Store and serve application resources locally
• Store data locally in a fully-searchable relational database
• Run asynchronous Javascript to improve application responsiveness

It is a similar idea with Apollo which enable offline use of web applications. From now on, users can store data locally in their database on their own computer. So that some users can use the web application they like, at the same time prevent their sensitive information being hacked by storing their information locally.
