Cookie Policy

What Are Cookies?

Cookies are small text files that are stored in your browser when you visit websites. They help us ensure the proper functioning of the website, remember your preferences, and improve our services.

What Cookies We Use

Essential Cookies

These cookies are necessary for the website to function and cannot be disabled. They include:

  • session – user login
  • guest_id – visitor identification for the shopping cart
  • email_verification – email verification

Functional Cookies

These cookies enable enhanced features and personalization:

  • theme – light/dark mode preference

Analytics Cookies

These help us understand how visitors use the website so we can improve it. Measurement is provided for us by Google Ireland Limited; when something breaks, Functional Software, Inc. (Sentry) also records that session so we can find out what went wrong. Google's tags load straight away, but with every consent set to “denied”: until you consent, they store nothing on your device and send Google only anonymous signals without cookies. Sentry's session recording does not start at all without your consent.

Marketing cookies

We use these to measure how well our advertising works — so we know which ads lead to a real order, and stop paying for the ones that do not.

With your consent we measure advertising using cookies from Google Ireland Limited, Meta Platforms Ireland Limited and Heureka Group a.s. Google's tags load straight away, but with every consent set to “denied”: until you consent, they store nothing on your device and send Google only anonymous signals without cookies, for example that a page was viewed or an order was completed (Consent Mode v2). Without consent the Meta tool and the Heureka tools are not loaded at all, store nothing on your device, and the “Verified by Customers” badge is not shown. You can change your choice at any time under Cookie settings in the site footer — withdrawing consent is as easy as giving it.

With your consent we (niro3d.cz) also store our own cookie, n3d_attr, which holds only which ad brought you here (the Google or Meta click identifier and the campaign labels). If you place an order, we attach it to the order so we can tell Google that an ad led to a purchase; it expires after 30 days. Without consent we do not store it, and if you withdraw consent we delete it.

Managing Cookies

You can manage most cookies directly in your browser settings. You can block or delete cookies, but this may affect the functionality of the website.

Guides for individual browsers:

Third-Party Cookies

Third-party services may be used on our website:

  • Stripe – for payment processing
  • Google Ireland Ltd. – for traffic and advertising measurement (Google Ads)
  • Meta Platforms Ireland Ltd. – for measuring advertising effectiveness on Facebook and Instagram; loaded only with your consent

These services have their own privacy policies, which we recommend reviewing.
