Privacy Policy

App: Hanoi Rush  |  Developer: Primeacis  |  Last updated: September 28, 2026

Hanoi Rush is a free puzzle game based on the classic Tower of Hanoi. This policy explains what data the app handles and how.

Data We Collect

Hanoi Rush itself collects no personal data. The app does not ask for your name, email address, phone number, location, or any other personal information. The advertising services the app uses do collect some data on their own behalf — see Advertising below.

Data Stored on Your Device

The app saves a small number of preferences locally on your device using Android SharedPreferences. These values never leave your device:

This data is stored only on your device and is deleted when you uninstall the app.

Multiplayer & Firebase

When you use the multiplayer mode, the app connects to Google Firebase Realtime Database to create and join game rooms. The following temporary data is written to Firebase:

This data is used solely to synchronise the game between two players in real time. Room data is not associated with any personal information and may be automatically cleaned up after the session ends. Firebase is operated by Google; see Firebase Privacy and Security for details.

Advertising

Hanoi Rush shows interstitial ads at the end of a solo game, served by Unity Ads. The app also includes the Google AdMob SDK. These providers may collect data such as your advertising ID, approximate location, device and other identifiers, app activity, and app diagnostics, in order to show and measure ads. This data is collected and processed by the ad providers, not by Hanoi Rush itself.

For details, see Unity's Privacy Policy and Google's Privacy Policy.

Internet & Network Access

The app uses the internet only for the multiplayer feature (Firebase). No personal data is transmitted by Hanoi Rush itself.

Children

Hanoi Rush is suitable for all ages. The app itself does not knowingly collect personal data from children under 13; note that the advertising services described above may not be appropriate for a child-directed audience, and the target audience declared in the app's store listing takes precedence over this general statement.

Changes to This Policy

If this policy changes, the updated date at the top of this page will be revised.
