Privacy policy

Last updated: June 2026

This policy explains what the 24-0 app collects and why. The short version: 24-0 is a single-player game that works fully offline, it does not ask for an account, and it does not track you across other apps or websites.

Who we are

24-0 is published by Alex Walls trading as twentyfourzero. You can reach us about anything in this policy at hello@twentyfourzero.app.

What the app stores on your device

Your team history, your daily results and your preferences are saved on your device only. This data is not sent to us and is removed if you delete the app.

Advertising

The free app shows occasional full-screen adverts at natural breaks, served by Google AdMob (Google Mobile Ads). Adverts are served on a non-personalised basis, so the app does not use the advertising identifier (IDFA) and does not present an App Tracking Transparency prompt. Even for non-personalised adverts, the advertising SDK may process limited device and technical information (such as device type, coarse region, and signals used to limit repeat adverts and prevent fraud). See Google's policies for details. Buying the one-off Remove Ads purchase stops all adverts.

Analytics

We use privacy-light, aggregate analytics to understand how the game is played and to balance it, for example which mode was chosen or which result tier was reached. These events carry no personal data and are not tied to your identity.

Leaderboard and multiplayer

These features are optional and only used if you choose to take part. To appear on the daily leaderboard or in a multiplayer room you pick a public handle. We store that handle, a random identifier generated on your device (used to keep one ranked entry per day and to let you update your own row), and your season result for that day or room. We do not ask for your name, email or any account. If you never use these features, no data leaves your device.

Purchases

The Remove Ads purchase is handled by Apple through the App Store. Apple processes the payment; we do not receive or store your payment details.

Children

24-0 is a general-audience game and is not directed at children under 13. We do not knowingly collect personal data from children.

Data retention and your choices

On-device data stays until you delete it or remove the app. Leaderboard and room entries are kept to run those features. To request removal of a leaderboard entry associated with your handle, email us at hello@twentyfourzero.app.

Changes

We may update this policy as the app evolves. Material changes will be reflected here with a new date.
