Cookies Policy
Small files. Clear choices.
Cookies are small text files stored in your browser. We use as few as possible — and the ones we do use we explain here in plain English. You can change your preferences at any time using the button below.
Manage your consent:
1. What cookies are
Cookies are tiny text files stored by your browser when you visit a website. They allow the site to remember your actions and preferences (such as login state, language, font size) over time, so you don't have to keep re-entering them.
Cittopia also uses similar technologies including localStorage (browser storage) and sessionStorage — these store information directly in your browser without sending it to our servers.

| Category | What it does | Consent required? |
|---|---|---|
| 🔐 Strictly necessary | Authentication for City Login admins, security tokens, cookie consent itself | No — required to operate the service |
| 📊 Analytics | Aggregated, anonymised usage statistics via Google Analytics 4 (truncated IPs) | Yes |
| 🎨 Preferences | Remembers display choices (dark/light mode, language) | Yes |
