Consent and settings
When you first access HTA3D, you can accept all cookies, reject all non-essential cookies or customise your preferences.
Analytics cookies, advertising cookies and any other technologies requiring consent remain disabled until the user expressly authorises them.
Rejecting non-essential cookies does not prevent you from browsing our store, viewing products or placing an order, although some optional functions may not be available.
We do not consider inactivity, silence or simply continuing to browse the website to constitute acceptance of cookies that require consent.
Changing or withdrawing consent
You can reopen the cookie settings panel available on HTA3D at any time to review, change or withdraw the preferences you previously selected.
Withdrawing consent does not affect the lawfulness of processing carried out while that consent was valid.
You can also manually delete cookies that have already been stored using your browser's privacy settings.
