In short

VibeWorld is a collection of interactive 3D mood worlds that run in your browser. We don't have an account system yet: we never ask for your name, email or password. This page explains plainly what data is kept where while you use the site, and who it is shared with.

  • Your progress and preferences are stored only in your own browser.
  • We measure usage in aggregate, without knowing who you are.
  • Messages you send to a world's AI companion are passed to OpenAI to generate a reply.

What stays in your browser

Your profile, favorites, saved vibes, Memory Book, quests, fishing catch log and world progress are kept in your device's localStorage (for example vibe-profile, vibe-favorites, vibe-journey, vibe-memory-book, vibe-quests-v2, vibe-catch-log). This data is not sent to our servers.

Clearing this site's data in your browser settings deletes all of it permanently. Since there are no accounts, it can't be moved to another device or recovered by us.

Usage statistics

We use two kinds of measurement to improve the site:

  • Google Analytics 4: Google's analytics tool, used for aggregate statistics such as page visits. Google sets the _ga and _ga_* cookies for this.
  • Our own anonymous telemetry: a random visitor ID (vw_visitor_id) and session ID (vw_session_id) are created in your browser. Session start, page views, entering and leaving worlds and time spent there, the referring site, screen size and browser language are sent to our own server, together with the country provided by our hosting provider. These records do not identify you as a person.

The AI companion

In some worlds you can chat with an AI companion. Your messages, along with the last few messages of the conversation, are sent through our server to OpenAI (the gpt-4o-mini model) to generate a reply, and are automatically checked for inappropriate content. To prevent abuse, your IP address is held briefly in server memory to enforce an hourly message limit.

Please don't share personal information such as your name, address, phone number or health details in the chat.

Third parties

  • Vercel: hosts the site; technical server logs are kept there.
  • Google (Analytics): aggregate usage statistics.
  • OpenAI: replies from the AI companion.
  • YouTube: some worlds play background music through an embedded YouTube player; YouTube/Google may set their own cookies.

What we don't do

  • We don't sell your data.
  • We don't build advertising profiles.
  • Our fonts are self-hosted, so no requests go to Google Fonts.

The service is offered from Turkey. For your rights under Turkish Law No. 6698 (KVKK) and the GDPR, see the KVKK / GDPR page; for cookie details, see the Cookie Policy.
