Cookie Policy
Last Updated: September 30, 2025
Company: HK Midun Technology Limited (“MiiiSys”, “we”, “us”, “our”)
Jurisdiction: Hong Kong SAR
This Cookie Policy explains how we use cookies and similar technologies on our websites, dashboards and other online services (collectively, the “Services”). It should be read together with our Privacy Policy and Terms of Service.
Cookies are small text files placed on your device to store information. We also use pixels, SDKs, local storage and similar technologies (together, “cookies”).
We use cookies for the following purposes:
Strictly necessary – run the site, provide security, enable log-in and core features.
Preferences – remember your settings (e.g., language, time zone).
Performance/analytics – understand usage and improve Services (e.g., page performance, error diagnostics).
Marketing/advertising – measure campaigns and, where applicable, show relevant content.
Fraud prevention & security – detect abuse and protect accounts.
We may set our own cookies and allow selected providers to set cookies on our behalf (for analytics, performance, fraud prevention, or, where applicable, advertising). Third parties may process data according to their own privacy notices.
Examples (non-exhaustive):
Essential (first-party):session_id (session), csrf_token (session), consent_state (6–12 months).
Analytics (third-party): page views, device and event data; IP is shortened or pseudonymised where feasible.
Security/fraud (first/third-party): signals to detect unusual activity.
Marketing (third-party, where used): campaign attribution, conversion events.
A current list of third-party vendors and cookie durations is available at /cookie-list and within our consent tool.
For strictly necessary cookies, the legal basis is our legitimate interests in providing a secure, functional service.
For non-essential cookies (preferences, analytics, marketing), we rely on your consent. You can give or withdraw consent at any time via our cookie banner or Cookie Settings.
If you access the Services from the EU/UK, we will not set non-essential cookies until you opt-in.
Use our Cookie Settings to accept, reject, or change categories at any time.
You can also configure your browser to block/delete cookies. Help pages:
Chrome: chrome://settings/cookies
Safari: Preferences → Privacy
Firefox: Options → Privacy & Security
Edge: Settings → Cookies and site permissions
Blocking some cookies may impact site features (e.g., log-in, checkout, dashboards).
We currently honour Global Privacy Control (GPC) signals where legally required by treating them as an opt-out of sale/sharing or targeted ads. The Services do not respond to legacy “Do Not Track” (DNT) signals.
Cookie lifetimes vary: session cookies expire when you close the browser; persistent cookies last from a few hours up to 24 months unless you delete them earlier. See /cookie-list for details.
We may update this Cookie Policy from time to time. We will post the updated version here and adjust the effective date above. Material changes may also appear in the banner or by notice in-app.
