Privacy Policy
What this is
Bundoku is a free, hobby-scale Sudoku game. This page describes what data the game collects, how it is used, and your choices.
What we store in your browser
By default Bundoku does not collect personal information. Play is anonymous - there is no account.
- Local storage on your device: we save your puzzles, daily
streak, Tea House Logbook, and preferences (skin, sound, consent) using your
browser's
localStorage. This stays on your device and is never sent to a server. - Service worker cache: to make the game playable offline and on flaky connections, a service worker caches static assets (HTML, JavaScript, images) in your browser. This cache also stays on your device.
Advertising (future)
Bundoku is designed to support ad-supported play. As of this version no real ads are loaded - what looks like an ad slot is a labeled placeholder. When the game begins serving real ads via a third-party network, that network may set cookies and process technical information (device, IP, ad interactions) per its own policy. We will name the ad network here, show a consent banner, and respect your choice.
Children
Bundoku is not directed to children under 13 and does not knowingly collect personal information from children.
Your choices
- Clear local data: browser settings → site data → clear storage for this domain.
- Cookie consent: change your choice by clearing site data and reloading.
