Privacy Policy

Last updated: 7 October 2026

Nigiri Stack ("the app") is a puzzle game for iPhone, made by Jeffrey Choong.

What the app collects

Nothing. The app does not collect, send to any server, share or sell any personal information. It has no accounts, no analytics, no advertising and no tracking.

What stays on your device

The app saves a few things locally on your iPhone so the game can remember them:

your best scores for each belt speed
your music and sound-effects settings

This information never leaves your device. Deleting the app deletes it.

Network access

The app does not connect to the internet.

This website

This website uses no cookies and no analytics. It is hosted on Vercel, which, like any web host, may keep standard server logs of requests (such as IP address and time) for security and reliability.

Children

The app does not collect information from anyone, including children under 13.

Changes to this policy

If a future version of the app adds advertising, purchases or any data collection, this policy will be updated before that version is released, and the App Store privacy details will be updated to match.
