What is the significance of retaining form data on refresh or timeout?

Retaining form data on refresh or timeout is significant primarily because it prevents user frustration. When users fill out forms, they invest time and effort in entering their information. If the page refreshes or experiences a timeout, and their input is lost, it can lead to frustration and a negative experience. By retaining this data, users can maintain their progress without needing to re-enter everything, enhancing the overall usability of the web application and encouraging them to continue interacting with it. This user-centric approach is essential in web accessibility, as it significantly improves the experience for all users, particularly for those who may struggle with completing forms quickly due to various reasons.
