Last updated: November 8, 2026 Personal research project

HappyBiu is a personal research project for free browser games. It is not a commercial service. This page explains the small amount of data involved.

What stays in your browser

Theme, sound, best scores, and game saves are stored in your browser. They are not sent to us. Clear browser storage to reset them.

Hosting

Our hosting provider may process standard request data such as IP address, browser information, requested URL, time, and security signals to deliver and secure the site. We do not maintain our own server logs.

Ads and analytics

We do not currently load third-party ads, analytics, or tracking. We do not sell or share personal information. If we add ads later, we will update this page and use consent where required.

Children

The site is not directed to children. If you believe a child provided personal information, email us and we will delete it.

Email happybiu@a2do.com with any privacy question. You can also clear local storage at any time in your browser settings.
