You can create a page for yourself at http://datatoy.net/user/your_twitter_name just by following @datatoy on twitter.
Datatoy will follow you back and start creating your charts automatically. You don’t need to give us your password, authorise anything, or do anything else.
Once datatoy is following you, just start tweeting things like *food 10 biscuits to create your first collections.
