Twist Stack

A mobile game by Quick Flash

Last updated: October 5, 2026

1Overview

This Privacy Policy explains how Twist Stack ("the app", "we", "us") handles information when you play the game on Android. The game works fully offline. We never ask you to create an account or give us your name, email address or phone number.

2Information we collect

Game progress (on your device)

Your level, best Endless height, coins, unlocked disc skins, power-ups, daily reward streak, missions and settings are stored only on your device. We do not upload them to our own servers.

Usage analytics

Gameplay events such as levels started, completed or failed, tower height, perfect drops and rewards claimed, together with an app-instance identifier, device model, OS version, country and language.

Crash reports

If the app crashes, a report with the stack trace, device model, OS version, app version and the level being played is sent so we can fix the problem.

Advertising identifiers

The app shows ads through Google AdMob, which may use your device's Advertising ID and IP address to deliver, limit and measure ads (see section 4).

We do not collect your contacts, photos, precise location, microphone or camera data.

3How we use information

We do not sell your personal information.

4Advertising

Twist Stack is free and supported by ads from Google AdMob: full-screen ads between some levels, and rewarded ads that you choose to watch for a revive, double coins or a free power-up. Ads are never shown during play.

Where the law requires it (for example in the EEA, the UK and some US states), the app asks for your consent through Google's consent form before any ads are requested. You can review or change that choice at any time under Settings → Privacy & ads in the game. You can also reset or delete your Advertising ID, or opt out of personalised ads, in your Android device settings.

5Third-party services

The app uses the following services, each of which processes data under its own privacy policy:

Google AdMob

Ads and ad measurement. How Google uses data

Google User Messaging Platform

Collects and stores your ad consent choices. Privacy policy

Google Analytics for Firebase

Usage analytics. Privacy policy

Firebase Crashlytics

Crash reporting. Privacy policy

Google Play Services

Required to install and run the app from Google Play. Privacy policy

When you tap Share, a picture of your tower height and a short text are passed to the app you choose through Android's share sheet. We do not see what you share.

6Notifications

With your permission, the app shows at most one reminder per day (around 7 pm local time), and only if you haven't played that day. Reminders are scheduled on your device and no data is sent to a server to create them. You can turn them off in the game's Settings or in your Android system settings at any time.

7Children's privacy

Twist Stack is a general-audience game for players aged 13 and over and is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided personal information, contact us and we will delete it.

8Data retention

Game progress stays on your device until you uninstall the app or clear its data. Analytics data is kept by Google Analytics for Firebase for up to 14 months, and crash reports by Firebase Crashlytics for up to 90 days. Advertising data is retained according to Google's policies.

9Your rights & choices

10Security

Data sent to Google's services is encrypted in transit. Because we keep no accounts and no servers of our own, very little information about you exists for anyone to access. No method of transmission or storage is completely secure, but we use reputable providers and keep what we collect to a minimum.

11Changes to this policy

We may update this policy as the game changes. When we do, we will update the "Last updated" date at the top of this page. Significant changes will also be noted in the app's release notes.
