By default, this package saves all form data to localStorage, so you could just use localStorage.removeItem('key') to remove all data for your specifed key

So if you have this form, for example:

<form
	use:persist={{
		key: 'my-form'
	}}
>
	<label for="title">Title</label>
	<input type="text" name="title" />
	<label for="content">Content</label>
	<textarea name="content" />
	<label for="date">Date</label>
	<input type="date" name="date" />
	<label for="phone">Phone</label>
	<input type="tel" name="phone" />
	<label for="email">Email</label>
	<input type="email" name="email" />
	<button type="submit">Save</button>
</form>

Then somewhere in your code you would use localStorage.removeItem('my-form') to clear all the data. Hope this helps.
