 _What Input does not make assumptions about the input environment before the page is interacted with._ However, the `mousemove` and `pointermove` events are used to set a `data-whatintent="mouse"` attribute to indicate that a mouse is being used _indirectly_.

 ### Interacting with Forms
 
-Since interacting with a form _always_ requires use of the keyboard, What Input uses the `data-whatintent` attribute to display a "buffered" version of input events while form `<input>`s, `<select>`s, and `<textarea>`s are being interacted with (i.e. mouse user's `data-whatintent` will be preserved as `mouse` while typing).

+### Default Behavior
+
+#### Persisting Input/Intent Across Pages
+
+By default, _What Input_ uses [session storage](https://developer.mozilla.org/en-US/docs/Web/API/Window/sessionStorage) to persist the input and intent values across pages. The benefit is that once a visitor has interacted with the page, subsequent pages won't have to wait for interactions to know the input method.
+
+This behavior can be disabled by adding a `data-whatpersist="false"` attribute on either the `<html>` or `<body>`.
+
+```html
+<html dir="ltr" lang="en" data-whatpersist="false">
+  ...
+</html>
+```
+
+or
+
+```html
+<body data-whatpersist="false">
+  ...
+</body>
+```
+
+Session storage can be cleared at any time with:
+
+```javascript
+whatInput.clearStorage()
+```
