Last Updated: September 22, 2026
Introduction
This Cookie Policy explains how Hanafuda Legends uses cookies and similar tracking technologies on our website. This policy should be read alongside our Privacy Policy.
What Are Cookies?
Cookies are small text files that are placed on your device when you visit a website. They are widely used to make websites work more efficiently and provide information to website owners.
Types of Cookies We Use
Essential Cookies
These cookies are necessary for the website to function properly. They enable core functionality such as:
- Authentication: Maintaining your login session
- Security: Protecting against fraud and unauthorized access
- Preferences: Remembering your settings and preferences
Examples:
- Session tokens for authentication
- Security tokens for CSRF protection
- hf_guest_id (localStorage): anonymous visitor id so a private-room session can be linked if you later create an account. Necessary — not used for advertising.
Can you opt-out? No - these cookies are essential for the website to work.
Functional Cookies
These cookies enhance functionality and personalization:
- User Preferences: Remembering your game settings
- Localization: Storing language preferences
- User Interface: Remembering UI customizations
Examples:
- localStorage data for user preferences
- Game state information
Can you opt-out? Yes - but some features may not work properly.
Analytics Cookies
These cookies help us understand how visitors interact with our website:
- Usage Statistics: Page views, time spent, click patterns
- Performance: Identifying technical issues
- Improvements: Understanding what features are most used
Examples:
- _ga and _ga_* — Google Analytics 4, used to distinguish users and maintain session state. Set by Google, retained for up to 2 years.
Can you opt-out? Yes. These cookies are not set until you consent, and you can withdraw consent at any time using the privacy button on our website.

Our mobile applications do not display advertising, do not use advertising identifiers, and do not track users as defined by Apple's App Tracking Transparency framework.
Provider: On our website (hanafudalegends.com), Google LLC, through Google AdSense.
Can you opt-out? Yes. On our website (hanafudalegends.com), in the EEA and UK these cookies are not set unless you consent. Elsewhere you can opt out of personalised advertising at https://adssettings.google.com. Opting out does not remove ads on the website; it makes them less relevant.
