Privacy Policy

Last updated 7 September 2026

Chainfall ("the app") is a single-player puzzle game published by TSANG PO WING. This policy explains what the app does and does not do with your information. In short: the app collects no personal data and sends nothing about you anywhere.

Information the app does not collect

Chainfall does not collect, store off your device, transmit, or sell any personal information. It contains no analytics, no advertising, no tracking, and no third-party SDKs. It asks for no permissions. It makes no network connections of its own and is fully playable offline.

Information stored on your device

The app saves your game data — scores, stars, statistics, settings and daily-task progress — locally on your device using the standard iOS preferences store. This data never leaves your device, is not accessible to us, and is permanently deleted when you remove the app.

Game Center

If you are signed in to Apple's Game Center, the app submits your Time Attack and Endless scores and your achievement progress to Game Center so that leaderboards and achievements function. This feature is provided by Apple and is governed by Apple's Privacy Policy. The app receives only an anonymous player identifier from Apple and stores no additional information about you. If you are not signed in to Game Center, nothing is submitted and no identifier is used.

Children

Chainfall is suitable for all ages. It collects no data from anyone, including children. It contains no user-generated content, no chat, no social features and no links out of the app other than to this policy and the support page.

Changes to this policy

If this policy changes, the revised version will be posted on this page with an updated date above.
