Always on 严格必要 — the booking engine won't run without these 3 cookies

These keep the session alive, remember your group size between pages, and let us verify a payment at checkout. They don't track you, aren't read by advertisers, and carry no identifier beyond a session ID. Turning them off would mean the site literally can't complete a booking — which is why the toggle is locked.

Optional 功能 — remembers your language, preferred guide language, currency 3 cookies

These make the site feel like it remembers you: interface language, currency, the guide language you last selected for a tour. Used only to personalise your visit — never read by advertisers. If off, the site still works but defaults (English, EUR, English guide) apply every page load.

Optional 分析 — anonymous usage statistics 4 cookies

Google Analytics 4 with IP anonymisation, ad-signals disabled, demographics off. We see how many people arrive, which page they land on, where they drop off — not who they are or what else they look at on the web. We use this to decide what to fix next, nothing else.

Optional 营销 — retargeting and campaign attribution 3 cookies

If on, we tell Meta and Google Ads that you visited us. They use that to re-show our palace tours to you and to measure which ads worked. 默认关闭 — we treat marketing cookies as opt-in, not opt-out, regardless of your country's legal minimum.

Where the data goes

What happens to the data behind each cookie you allow.

Every category you enable triggers a specific data flow. Here's the chain from the moment a cookie is set to the moment its data is used — or deleted.

01
Set on your browser

Cookie is set on the Istanbul Tourist Information domain when you consent. Lives in your browser's storage, not on our server.

02
Read on each visit

Sent back to us on each request. Used to identify the session or preference — nothing else.

03
Aggregated

Analytics feed into GA4 anonymised. Marketing feeds into Meta / Google Ads as opaque IDs.

04
Expires or deleted

At expiry or when you revoke consent here, the cookie is deleted. Downstream data purged per vendors' retention windows.
