Thanks. Fixed.
One con of local storage is that it can only store string. The item has to be converted to its original type while loading. Another option to avoid the conversion I did is to stringify and parse the item during storing and loading.

}, [])

useEffect ( () => {
localStorage.setItem("startTime", startTime)
localStorage.setItem("isUserBreaking", isUserBreaking)
localStorage.setItem("ClockKey", ClockKey)
localStorage.setItem("isClockPlaying", isClockPlaying)
localStorage.setItem("workDurationMinutes", workDurationMinutes)
localStorage.setItem("breakDurationMinutes", breakDurationMinutes)
localStorage.setItem("Minute", minute)
localStorage.setItem("Second", second)
})

/**
* Load a item from the local storage with the key itemName and set the item with the itemSetFunc.
* itemType indicates what type the item should be converted to. Since local storage only stores strings,
* the item needs to be converted.
* @param {*} itemName
* @param {*} itemSetFunc
* @param {*} itemType ONLY choose from "string", "boolean" and "number"
*/
function loadItemFromLocalStorage(itemName, itemSetFunc, itemType) {
const data = localStorage.getItem(itemName)

itemSetFunc(data == "true")
} else if (itemType == "number") {
