Privacy Policy — Number Clash

Last updated: 2026-07-09

Number Clash ("the Game") is a number-placement puzzle game with a solo mode and a same-device local multiplayer (pass-and-play) mode. This policy explains what data the Game and its third-party services collect, and how it is used.

Summary

The Game does not ask you to sign in, does not run its own servers, and requires no network connection to play. However, the Game shows advertisements through Google AdMob, and AdMob collects certain data to serve and measure ads. The Game also supports an optional in-app purchase to remove ads.

Data stored on your device

The Game saves the following locally on your device only; it is not sent to us:

• Your high scores and match history (solo runs and versus matches).
• Your settings — sound, vibration, and dark-theme preferences.
• Your "remove ads" purchase status, if you buy it.

Clearing the app's storage or uninstalling the Game removes these values.

Data collected by advertising (Google AdMob)

To display ads, Google AdMob and its partners may collect and process:

• Advertising identifiers (e.g. Android Advertising ID) and device identifiers
• Device information (model, OS version, language, network)
• Approximate location (derived from IP address)
• Ad interaction data (ads shown, taps, app activity related to ads)

This data is collected by Google as a third party and is used to serve, personalize, measure, and prevent fraud in advertising. We do not receive your personal identifiers from this process. For details, see Google's Privacy Policy and How Google uses information from AdMob.

Purchases

The optional "Remove ads" purchase (and any other in-app products) is processed by Google Play Billing. Payment details (card numbers, etc.) are handled entirely by Google; the Game never sees or stores them. When you remove ads, advertising and its related data collection stop.

Your choices

• You can reset or delete your Advertising ID in your device's settings, and opt out of ad personalization.
• In regions that require it (e.g. the EU/UK), the Game shows a consent prompt and respects your choice about personalized ads.
• Buying "Remove ads" turns off advertising and its data collection.
• Clearing the app's storage or uninstalling removes the locally stored values above.

Children

The Game is intended for a general audience. Where the audience may include children, only non-personalized, family-appropriate ads are requested in line with Google Play and AdMob policies.

Data sharing & retention

We do not sell your data. Advertising data is processed by Google/AdMob under their own policies and retention periods. We do not maintain our own copy of it.

Changes

If this policy changes, the updated version will be posted at this address with a new "Last updated" date.
