Cache User Data

[heathharrelson]

Description

It's possible that users might take some time to enter all of their conditions. To prevent data loss if the browser or tab is closed, cache their data (@jmcmurry suggested localStorage).

User Story

As a user I want my progress to be saved.

So that I don't have to start over using the tool if I am interrupted.

Acceptance Criteria

• Application state survives a restart:
  • Session ID
  • Terms selected
  • Feedback flag
• Application state is cleared on the results page

Open Questions

• How do we deal with public computers?
• Is there a reasonable amount of time after which data should be discarded?

I would say that given the survey should take no more than 5-20 minutes, we should cap at 30 minutes. The intro should include "This survey should take you 5-20 minutes; for security purposes, your session will time out after 30 minutes of inactivity." cc: @mellybelly
