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.

6. COOKIE CONTROLS

When non-essential technologies are present, the consent interface must provide equally accessible options to: - Accept optional technologies; - Reject optional technologies; - Choose categories. No optional category may be pre-selected. A user must be able to reopen the settings and withdraw consent as easily as it was given. Withdrawing consent must prevent future use of the relevant non-essential technologies.

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.
