This policy covers the World Clubs website (world-clubs.com) and the Japan Nightlife / 夜な夜な websites and mobile apps (japannightlife.jp, yona-yona.jp), operated by Enfour, Inc., Tokyo, Japan ("we"). These services share one optional user-account system.
Account data (optional — you can browse without an account): a nickname, an optional email address, an optional password (stored only as a secure hash), optional messenger handles you choose to add (LINE, KakaoTalk, Instagram, WeChat, WhatsApp, Facebook), a preferred language, an optional location description, and an optional avatar image.
Social sign-in: if you sign in with Apple, Google or Facebook we receive and store your account identifier at that provider, and — if you share them — your name and email address (Apple lets you hide your email; that works fine with us). We never see your password for those services. An email address is not required to use an account.
Notifications: if you enable push notifications we store your device's push token so we can deliver them; it is linked to your account when you are signed in.
Activity: content you create (favorites, votes, reviews, posts) is stored with your account. Location coordinates you share for "nearby" searches are used to answer the search and are not kept as a location history. Our servers keep standard technical logs (IP address, request time) for security and operations.
Running the services: signing you in and keeping you signed in, showing your content, sending notifications you enabled, answering searches, keeping rankings fair, and preventing abuse. We do not sell personal data and we do not use it for third-party advertising.
Sign-in verification is performed with the provider you choose (Apple, Google or Facebook). Push notifications are delivered through Apple, Google and web push services. Venue information shown in the services is compiled from public sources and mapping providers. These parties process only what is needed for their function.
world-clubs.com uses a session cookie to keep you signed in. The apps and the Japan Nightlife sites use a sign-in token stored on your device. We do not use third-party advertising or tracking cookies.
You can request deletion of your account and its data at any time by emailing [email protected]. If you signed in with Facebook, removing the app in your Facebook settings also triggers automatic deletion (see our data deletion page). Deleting your account removes your profile, sign-in identities, sign-in tokens and notification links.
Account data is kept while your account exists. Passwords are stored only as salted hashes; social sign-in credentials are verified cryptographically and provider secrets are never exposed to your browser. Data is stored on our servers in Japan.
We will update this page when the policy changes. Questions: [email protected].
