SoundReady does not store any password or contact information of its users. We do however, store your name and Rdio Api token in order to make multiple playlist creations a breeze. We will never disclose or sell any of your playlist creation or search habits to any third party, but an anonymized version of this information might be used to help improve the performace/featureset of the site. All session information is stored client-side, so simply clearing your browser settings will wipe all that out.
Any location data we use to help improve your expirience is stored locally using client-side cookies. You will always be prompted before we use your location and this data can always be removed by clearing your browser's cookies.
