Cookie Policy
Last updated: October 30, 2026
This Cookie Policy explains how YUCTS (櫻佑旅遊) (hereinafter the "Service") uses cookies and similar technologies on its websites. Please read it together with our Privacy Policy.
1. What Are Cookies
Cookies are small text files that a website stores on your device, used to maintain login status, ensure security, remember preferences, or provide analytics and advertising functions.
2. Scope
- This Policy applies to the Service's websites: the forum (forum.yucts.com), the information site (yucts.com), yucdu.com, YUCTS Coupon (coupon.yucts.com), YUCTS Transit (transit.yucts.com), and YUCTS Docs (docs.yucts.com).
- The Yucts Travel App and the backend API use token-based authentication and do not use cookies. Advertising and tracking within the App are handled separately in accordance with the App Tracking Transparency (ATT) framework (see Section 5).
- The YucDu App is a read-only reader that likewise does not use cookies between itself and the backend API, and displays no advertising and performs no tracking.
3. Strictly Necessary Cookies (Cannot Be Disabled)
These are necessary to maintain the website's basic functions, login, and security, including (forum):
| Cookie | Purpose |
|---|---|
xf_session | Stores the session identifier |
xf_user | Maintains login status across sessions |
xf_csrf | Prevents cross-site request forgery (CSRF), guarding against malicious requests |
xf_consent | Stores your cookie consent choices |
xf_language_id | Remembers the language you selected |
In addition, the Service uses Cloudflare to provide security protection and content delivery, which may set cookies necessary to keep the Service secure and operating normally.
The cookies the forum actually uses depend on its settings; see the forum's "Cookie usage" help page for the full list.
yucts.com and yucdu.com: when you sign in to a website account (for example, to comment), cookies needed to keep you signed in, maintain your session, and protect security are used (their names begin with wordpress_); if you sign in with a Google account, Google may also set its own cookies.
4. Functional Cookies (Optional)
Used to enhance the user experience, for example:
| Cookie | Purpose |
|---|---|
xf_emoji_usage | Remembers the emoji you have used recently, for convenient selection when composing |
Other cookies and storage by website
| Website | Details |
|---|---|
| YUCTS Coupon | Sets yucts_coupon_locale to remember your language (kept for one year) only when you choose a language yourself. No ad tracking |
| YUCTS Transit | The site itself sets no cookies, and the language is set by the URL; traffic analytics use cookie-free Cloudflare Web Analytics. When ads are shown, Google AdSense and its partners may set advertising cookies (consent is requested first in the European Economic Area, the United Kingdom, and Switzerland); see Section 5 of the Privacy Policy |
| YUCTS Docs | No cookies; traffic analytics use cookie-free Cloudflare Web Analytics. If you add it to your Home Screen, pages you have viewed are kept in the browser's offline storage |
5. Advertising and Tracking (App)
The Yucts Travel App displays advertising through Google AdMob. On iOS, the App may use the advertising identifier (IDFA) to provide personalized advertising only after seeking your consent in accordance with the ATT framework; if you do not consent, non-personalized advertising will still be shown. You may change the authorization under iOS "Settings → Privacy & Security → Tracking," or upgrade to Yucts Plus to remove in-app advertising. For details, see Section 5 of the Privacy Policy.
In some regions, the App first shows Google's ad consent screen; you can change your choice later under "Profile & settings" → "App Permissions" → "Ad Privacy Options".
6. Third-Party Embedded Content Cookies
When a page embeds content from third-party platforms (such as Facebook, Instagram, YouTube, TikTok, Spotify, Reddit, etc.), those third parties may set their own cookies, managed by them respectively; this Policy does not apply to such third parties.
7. How to Manage Cookies
- You can view, delete, or block cookies through your browser settings (Chrome, Firefox, Safari, Edge, Opera, etc.).
- You can change your preferences for optional cookies through the website's cookie consent settings.
- Please note that disabling certain necessary cookies may cause login or some functions to not work properly.
8. Policy Updates
