Cookie Policy
Last updated: 26 July 2026
This Cookie Policy explains how operium.store uses cookies, browser storage and similar technologies. It applies to the OPERIUM corporate website. Individual products may publish a separate cookie policy for their own application.
1. WHAT THESE TECHNOLOGIES ARE
Cookies are small files or values stored on a user’s device.
Similar technologies include local storage, session storage,
tracking pixels, scripts, tags and other mechanisms that store
information on or access information from a device.
2. STRICTLY NECESSARY TECHNOLOGIES
We may use technologies that are strictly necessary to:
(a) provide a requested page or service;
(b) maintain a secure authenticated session;
(c) protect the website against fraud or abuse;
(d) balance traffic and maintain availability;
(e) remember a privacy or cookie choice;
or
(f) complete an action specifically requested by the user.
Where the law does not require consent for a strictly necessary
technology, we still describe it in the inventory below.
3. FUNCTIONAL TECHNOLOGIES
Functional technologies may remember choices such as language,
region, display preferences or interface settings.
Where a functional technology is not strictly necessary, it will
not be activated until the required consent has been obtained.
4. ANALYTICS TECHNOLOGIES
Analytics technologies help understand how pages perform and how
visitors use the website.
Non-essential analytics technologies must remain disabled until the
user has actively consented.
Rejecting analytics must not prevent access to the corporate
website.
5. MARKETING TECHNOLOGIES
Marketing, advertising, cross-site tracking and remarketing
technologies must remain disabled until the user has actively
consented.
OPERIUM must not treat continued browsing as consent.
7. BROWSER CONTROLS
Users may also delete or block cookies through their browser.
Blocking strictly necessary technologies may prevent some requested
functions, including sign-in or security functions, from operating.
8. THIRD-PARTY TECHNOLOGIES
Where a third party places or accesses information on a user’s
device, the cookie inventory must identify that third party and
explain its purpose.
Third-party technologies must not be described merely as
“partners” where the provider’s identity is known.
9. CHANGES
The inventory and this Policy may be updated when the website’s
technologies change.
The “Last updated” date identifies the current version.
