## IndexedDB

WooCommerce POS uses IndexedDB to persist the product database on your computer or device. [IndexedDB](http://www.w3.org/TR/IndexedDB/) is currently a 'Candidate Recommendation' specification by the W3C and is not implemented by all browsers. To see if your browser is compatible please check [caniuse.com](http://caniuse.com/indexeddb).

WooCommerce POS also uses the [Flexbox Layout](http://www.w3.org/TR/2015/WD-css-flexbox-1-20150514/) module, currently a W3C Last Call Working Draft. To see if your browser is compatible please check [caniuse.com](http://caniuse.com/flexbox).

## Private Browsing

Some browsers will disable access to IndexedDB when [Private Browsing](https://en.wikipedia.org/wiki/Privacy_mode) is enabled. This will result in an IndexedDB Error shown below.
