No material preference is remembered
Melivorak does not save which samples you compare. The material table, method tabs and exercise selections restart with the page. There is no persistent browser notebook, tracking pixel or analytics cookie. Assets are supplied by the site itself.
A short-lived form safeguard
A contact request uses a randomly generated token backed by a session cookie belonging to this domain. The HttpOnly setting prevents JavaScript from reading the cookie, and the session ends with the browser session. This helps distinguish an intended submission from a request originating elsewhere. Disabling cookies can stop the contact action; it does not stop you studying the sample notes.
What the browser cannot remove
Your browser can discard its own session data through site settings. It cannot delete an enquiry already written to Melivorak’s server. For that, identify the saved receipt in a contact request. Read the privacy notice for the fields retained and the operator’s removal process.
