# Why am I getting an IndexedDB Error?

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.

## Adding WooCommerce POS to the home screen

Web pages that [added to the home screen](http://www.howtogeek.com/196087/how-to-add-websites-to-the-home-screen-on-any-smartphone-or-tablet/) will be automatically launched in privacy mode. Unfortunately this means that you cannot add WooCommerce POS to your iOS or Android home screen at this time.

## Other causes

Some browser may 'lock' IndexedDB access to one tab at a time. An IndexedDB error may occur if you attempt to operate WooCommerce POS in two tabs simultaneously.
