Our current approach
China Travel Kit does not use third-party advertising cookies or cross-site advertising profiles. We use a small number of essential first-party cookies and browser-storage entries. The Google Analytics tag loads only after you explicitly consent.
Essential cookies
- ctk_traveller_session: an HTTP-only sign-in session, normally lasting no more than 30 days.
- Temporary Google sign-in cookies: OAuth state, PKCE verification and return path, normally removed after the callback or about 10 minutes.
- ctk_locale: remembers the chosen language. The admin area uses a separate secure session cookie available only to administrators.
Local browser storage
- ctk-theme stores the light, dark or system theme choice.
- ctk-saved-items stores items you actively save before or without account sync.
- The before-you-go checklist stores items you actively mark complete.
- Session-storage page-view, source-channel and commercial-impression markers prevent duplicate counts in one tab and retain only the coarse acquisition channel during navigation. They are normally cleared when the tab closes.
- ctk_analytics_consent is stored in localStorage to remember whether you accepted or declined optional analytics. You can change it using Cookie settings in the page footer.
Optional analytics cookies
After you consent, Google Analytics 4 processes page addresses, acquisition source, device and browser category, approximate region, and visit and engagement timing, and may set cookies such as _ga and _ga_*. Google Signals and advertising-personalization signals are disabled. We do not send your site account ID, itinerary contents or form text to GA4.
Affiliate and external sites
We do not allow a partner to set its cookies on this site before you follow a labelled affiliate link. Once you enter a partner site, it may use attribution or functional cookies under its own policy. Review and manage those choices on that site.
Your controls
- You can delete or block cookies, localStorage and sessionStorage in your browser.
- Blocking essential cookies will break sign-in, Google sign-in or language preferences. Clearing local storage removes device-only saves, theme and checklist progress.
- On your first visit you can choose Accept analytics or Essential only. You can change the choice later through Cookie settings in the page footer. Declining prevents Google Analytics from loading and does not affect core site functions.
Changes and contact
We will review this policy before adding analytics, advertising, payment or other features that change browser-storage use. Contact us at the address above to ask about any cookie or storage entry.
Optional interaction measurement
With analytics consent and an already loaded GA4 tag, we measure browser saves, confirmed new-trip saves and clicks on booking, official-site, map and planning links. We send only fixed action categories and language, not content identifiers, destinations, trip details, form text or private URLs. A browser save does not confirm account sync, and a link click is not a booking. You can withdraw consent in Cookie settings.
This page describes China Travel Kit’s current practices in clear language. We will update the text and date when features, partners or applicable requirements change.
