1. What we mean by cookies
“Cookies” here includes HTTP cookies, localStorage, sessionStorage and similar technologies that store information on your device. Effective date: 2026-07-18. Last updated: 2026-07-18.
This notice is provided for transparency and does not constitute legal advice. Mandatory consumer and data-protection rights in your country of residence always prevail.
2. Categories
We group storage into four categories. You can accept all, reject optional categories, or customise checkboxes in the consent dialog.
- Necessary — localStorage key z3r-cookie-consent (consent record only). Always on.
- Preferences — localStorage keys z3r-theme, z3r-locale, z3r-announce-v1. Written only after you opt in to Preferences; otherwise purged.
- Analytics — reserved; no keys or scripts in the current release.
- Marketing — reserved; no keys or scripts in the current release.
3. Legal basis
Necessary storage: strictly necessary to remember your consent choice (ePrivacy).
Preferences, analytics, marketing: consent. Theme and language are not stored without Preferences. Withdraw anytime via Your Privacy Choices. GPC signals are honoured as opt-out of analytics and marketing.
Russia 152-FZ / EU GDPR / NZ Privacy Act principles apply to any personal data derived from these technologies.
4. Managing choices
Use the cookie banner on first visit, or open “Your Privacy Choices” in the footer. Declining Preferences deletes theme/language/announcement keys. Clearing site data removes consent until you choose again.
