iPad Offline Web App with Multiple Entries

I've found a ton of information on LocalStorage with HTML5 but they all focus on persistent single entries being saved.

I need to be able to have a contact form (simple name/email/phone) that gets saved to the iPad and then allows another person to submit an entry to save to the iPad locally (no Wifi/Internet available).

Then I want to be able to go in later and grab all the entries that were made in whatever format available.

Any direction & help would be appreciated.

I searched on Stackoverflow & Google but still couldn't find multiple entry tutorials or examples.

Thanks!
