I tweaked Object's answer to remove the key from localstorage if hidden. From what I could find, there isn't a need to check if the key exists before attempting to remove. This reduces the amount of items being kept in localstorage.
$(document).ready(function () {
//If shown.bs.collapse add the unique id to local storage
$(".collapse").on("shown.bs.collapse", function () {
localStorage.setItem("coll_" + this.id, true);
});
//If hidden.bs.collaspe remove the unique id from local storage
$(".collapse").on("hidden.bs.collapse", function () {
localStorage.removeItem("coll_" + this.id);
});
//If the key exists and is set to true, show the collapsed, otherwise hide
$(".collapse").each(function () {
if (localStorage.getItem("coll_" + this.id) == "true") {
$(this).collapse("show");
}
else {
$(this).collapse("hide");
}
});
});

Use can use below way to keep state after a refresh.
Both of these can store client-side data which will preserve your state.
Provide each collapse element a unique id across the website so there'll be no room for conflict. So based on user action collapse or un-collapses an element you'll update state in storage. Now using bootstrap event and API, you can collapse or un-collapses an element based on storage state.
Here is a working demo: https://jsfiddle.net/c1ovt5g4/
<button class="badge badge-danger left" type="button" data-toggle="collapse" data-target="#personal-data" aria-expanded="false" aria-controls="personal-data">Personal Data</button>
<button class="badge badge-danger " type="button" data-toggle="collapse" data-target="#email-change" aria-expanded="false" aria-controls="email-change">Email Change</button>
<button class="badge badge-danger" type="button" data-toggle="collapse" data-target="#user-history" aria-expanded="false" aria-controls="user-history">User History</button>
<div class="collapse" id="personal-data"> PERSONAL DATA</div>
<div class="collapse" id="email-change"> EMAIL CHANGE</div>
<div class="collapse" id="user-history">USER HISTORY</div>
$(".collapse").on("hidden.bs.collapse", function() {
localStorage.setItem("coll_" + this.id, false);
});
$(".collapse").on("shown.bs.collapse", function() {
localStorage.setItem("coll_" + this.id, true);
});
$(".collapse").each(function() {
if (localStorage.getItem("coll_" + this.id) == "true") {
$(this).collapse("show");
}
});
