Policy
個人情報の取り扱いRyuheidou (hereinafter “we” or “us”) sets out this Privacy Policy regarding the handling of users’ personal information in the browser game “FURU FURU DICE” (hereinafter “the Game”), which we provide.
Everything is processed inside your browser
We do not send, collect, or share any information, including your actions during play, with any external server.
1. Information We Collect
The Game does not collect any of the following information.
- Personally identifiable information such as name, email address, and phone number
- How you use the Game, such as rolls, history and settings
- Location information
- Device-specific identifiers (advertising ID, device ID, etc.)

2. Device Permissions
The Game does not use any of the following browser permissions.

For the “Shake your phone to roll” feature, the Game uses your device’s motion sensor (accelerometer). It is used only to detect whether the device has been shaken, and the values are never saved or sent. On iPhone and some other devices, you are asked for permission the first time; all other features keep working even if you do not allow it. Turning off “Shake your phone to roll” in the settings stops its use.
On supported devices, the Game uses vibration while the dice roll. Turning off “Vibration” in the settings stops its use.
Sound effects are played using the browser’s standard audio feature (Web Audio). It only produces sound; nothing is recorded.
3. Local Storage and Cookies
So that you can pick up where you left off, the Game saves the following data to your browser’s local storage.
- Settings (number of dice, the faces, colors, table, and on/off switches such as sound effects)
- Roll history (up to 40 rolls)
The saved data has the following characteristics.
- It is stored only inside your browser
- It is never sent to any external server
- The history can be erased with “Clear history” on the history screen, and all data can be erased by deleting the site data in your browser
The Game does not use cookies.
4. Use of Third-Party Services
The Game itself does not use the following services.
- Advertising services
- Access analytics services (such as Google Analytics)
- Crash reporting services
- Social media integration
The font used for on-screen text is loaded from Google Fonts. This involves ordinary communication (such as your IP address) between your browser and Google’s servers, but nothing about how you use the Game is sent.
Note that the website that hosts the Game (ryuheidou.com) uses Google Tag Manager to measure traffic across the whole site. This applies to the site as a whole and does not collect any information specific to the Game.
5. Internet Connection
An internet connection is required to open the Game, but all game processing takes place inside your browser. Your actions and results during play are never sent over the internet.
6. Advertising and In-App Purchases
The Game shows no advertisements and has no payment features. It is completely free to use.
