Cookie Policy
Last Updated: 10.11.2026
1. Introduction
This Cookie Policy explains how STELLAR, operated by ALTIVO Sp. z o.o., uses cookies and similar technologies on its website. It is part of our Privacy Policy.
We set only cookies that are strictly necessary for the site to work: keeping you signed in, protecting our forms and remembering your currency. We don't run analytics, advertising or tracking cookies, and no third-party scripts set cookies on our pages.
2. What Are Cookies
Cookies are small text files a website stores in your browser. Similar technologies include the browser's local storage and session storage, which keep small values on your device without sending them to us with every request.
3. Cookies We Use
Every cookie we set is in the Necessary category. Without them you cannot sign in or pay, so they are always on; the law does not require consent for them.

5. Other Websites
When you confirm a card payment with your bank (3-D Secure) or sign in with a third-party account, that step happens on the page of the payment processor, your bank or the sign-in provider. Those pages may set their own cookies under their own policies; we do not control or read them.
6. Managing Cookies
Because we use only necessary cookies, there are no optional cookie categories to switch on or off. The cookie notice tells you this once and is not shown again after you close it.
You can delete cookies or block them in your browser settings at any time. If you block our cookies you will not be able to sign in or pay.
7. Do Not Track
We do not run tracking technologies, so a Do Not Track signal does not change how our site behaves.
8. Changes to This Policy
If we add a cookie, we list it here and update the date at the top before it is used. If we ever wanted to use cookies that need your consent, we would ask for it first.
