The form session
When the contact endpoint is used, a necessary session cookie supports the security token. It is not an advertising identifier. Blocking cookies can prevent the form from completing; a storage error must not appear as a successful enquiry.
The saved comparison
The optional worksheet uses localStorage, not a cookie. It is saved only by the Save button and can persist after closing the browser. Clearing website data through your browser also removes it. Resetting a worksheet does not delete a server-stored enquiry.
Your controls
Use the Clear saved worksheet button in the footer to remove this site’s local comparison. Browser settings provide broader control over cookies and site data. If storage is blocked, the live worksheet still lets you consider options but cannot confirm persistent saving.
No hidden connection
Loading our local images, Bootstrap and jQuery does not require an external CDN. External support links are ordinary links; their destinations have separate storage policies. See Privacy for the distinction between local notes and submitted enquiries.
