Methods, systems, and apparatus, including medium-encoded computer program products, for providing local storage service to applications that run in an application execution environment. In one aspect, a method includes receiving a request from one of the applications, wherein the request triggers local storage of information; obtaining an encryption key based on identifiers including a first identifier corresponding to the application execution environment, a second identifier corresponding to the one application, and a third identifier corresponding to the computing apparatus; encrypting the information using the encryption key; and storing the encrypted information in the computing apparatus. |
