There are a number of web technologies that store data of one kind or another on the client-side (i.e., on your local disk). The process by which the browser works out how much space to allocate to web data storage and what to delete when that limit is reached is not simple, and differs between browsers.

The simple sample app searches images using the Bing Search API and saves those images as Base64 strings to an object store in an IndexedDB database. This is a repository for the development of the Indexed Database (Third Edition) specification. IndexedDB is a low-level API for client-side storage of significant amounts of structured data, including files/blobs. This API uses indexes to enable high-performance searches of this data.
