FUSE
Last updated: 25 September 2026
Fuse: Chain Reaction (“Fuse”) is a puzzle game that keeps your progress on your device. This policy explains what that means.
Nothing. Fuse has no account of its own, no server, no analytics and no advertising, and it contains no third-party code. We never receive anything about you or how you play.
Your Daily results and streak, your best Endless stage and Storm score, your player level and XP, a paused Endless run if you leave one, your spark bank, and your settings (sound, haptics, reduced effects, whether you finished the tutorial). They are kept in the app’s own storage on your device and are included in your device backup like any other app’s data, if you use backups. Deleting the app removes everything it stored.
Rankings use Apple’s Game Center, which is optional. If you are signed in to Game Center, Fuse sends your best Endless stage, your Storm scores and your player level to Apple’s Game Center leaderboards, where other players can see them next to your Game Center name and picture, and Fuse shows the leaderboards to you. This goes directly between your device and Apple; we do not receive it. Game Center is provided by Apple under Apple’s Privacy Policy, and you can sign out or change who sees you in Settings → Game Center. If you are not signed in, nothing is sent.
Fuse shares a result only when you tap Share. The text contains your score and a spoiler-free line of symbols; where it goes is up to you.
Fuse does not ask for your location, camera, photos, contacts, microphone or notifications.
The App Store gives developers aggregated, anonymous statistics such as download counts, depending on your device’s analytics-sharing setting. These never identify you or include anything from your games.
The game is suitable for all ages and we collect no data from anyone.
If this policy changes, the date above will change with it.
