The webpage with HTML, in which page will open with firstname, lastname, phone number, sex with three buttons which store the data, retrieve the data and clear the sex designation, here the code:

<!DOCTYPE html>
<html>
<body>
<form action="/action_page.php">
  <label for="fname">First name:</label><br>
  <input type="text" id="fname" name="fname" value="John"><br><br>
  <label for="lname">Last name:</label><br>
  <input type="text" id="lname" name="lname" value="Doe"><br><br>
  <label for="phone">Mobile Number:</label><br>
<input type="tel" id="phone" name="phone"><br><be>
 <label for="phone">Gender:</label>
  <input type="radio" id="male" name="gender" value="male">
  <label for="male">Male</label>
  <input type="radio" id="female" name="gender" value="female">
  <label for="female">Female</label><br><be>
  <input type="submit" value="store">
  <input type="submit" value="retrieve">
  <input type="submit" value="clear">
</form> 
</body>
</html>

The output of the page, look like:

To store the data on local storage, display the data on same page & clear the gender, javascript can be used.

function storedata()
{
sessionStorage.setItem('fi', document.getElementId('fname').value);
sessionStorage.setItem('la', document.getElementId('lname').value);
sessionStorage.setItem('mo', document.getElementId('phone').value);
}

function getdata()
{
document.getElementById('span1').innerHTML=session.Storage.getItem('fi');
document.getElementById('span1').innerHTML=session.Storage.getItem('la');
document.getElementById('span1').innerHTML=session.Storage.getItem('mo');
}

function sex() {
  document.getElementById("gender").reset();
}

The three function define the three buttons operations, here the final code of wepage:

<!DOCTYPE html>
<html>
<head>
<title></title>
<script>
function storedata()
{
sessionStorage.setItem('fi', document.getElementId('fname').value);
sessionStorage.setItem('la', document.getElementId('lname').value);
sessionStorage.setItem('mo', document.getElementId('phone').value);
}

function getdata()
{
document.getElementById('span1').innerHTML=session.Storage.getItem('fi');
document.getElementById('span1').innerHTML=session.Storage.getItem('la');
document.getElementById('span1').innerHTML=session.Storage.getItem('mo');
}

function sex() {
  document.getElementById("gender").reset();
}
</script>
</head>
<body>
<form action="/action_page.php">
  <label for="fname">First name:</label><br>
  <input type="text" id="fname" name="fname" value="John"><br><br>
  <label for="lname">Last name:</label><br>
  <input type="text" id="lname" name="lname" value="Doe"><br><br>
  <label for="phone">Mobile Number:</label><br>
<input type="tel" id="phone" name="phone"><br><be>
<div id="gender">
 <label for="phone">Gender:</label>
  <input type="radio" id="male" name="gender" value="male">
  <label for="male">Male</label>
  <input type="radio" id="female" name="gender" value="female">
  <label for="female">Female</label><br><be>
</div>
  <input type="submit" onclick="storedata();" value="store">
  <input type="submit" onclick="getdata()" value="retrieve">
   <span id="span1"></span>
  <input type="submit" onclick="sex()" value="clear">
</form> 
</body>
</html>
