Good morning, I need to do the following: The user types some text in an input and this text is not lost if he changes pages. This input has no submit button. How can I do this? Can you do without BD?

You can write the value of the input to a variable and then retrieve it with some event such as onchange , onclick and etc.
Functional example:
<html>
<head>
<title>Teste</title>
</head>
<body>
<script type="text/javascript">
function mostrarValor(){
var frm = document.frm;
var val1 = frm.valor1.value;
alert(val1 );
}
</script>
<form name="frm">
<input type="text" name="valor1" size="10" >
<button type="button" onclick="mostrarValor();">Veja os valores</button>
</form>
</body>
</html>

You can use jQuery to read the text written in this input: Javascript:
$("#teu_input_id").keyup(function(){
var input = $(this).val();
$.post("/backend.php", {"input": input});
});
PHP:
session_start();
$_SESSION['input'] = filter_var($_POST['input'], FILTER_SANITIZE_STRING);
On pages where you do not want to lose information: PHP
session_start();
$input = filter_var($_SESSION['input'], FILTER_SANITIZE_STRING);
HTML
<input type="text" name="teu_input" id="teu_input_id" value="<?=$_SESSION['input']" />
