Privacy Policy

Effective date: November 10, 2026

Nertz Score ("the app", "we", "us") is a score keeper for the card game Nertz, made by Matthew Audette (CGE Computers) for iPhone. This policy explains what the app stores, what the ads in it may collect, and the choices you have.

The short version

Your player names, games and scores stay on your phone. There is no account and we run no server that receives your data. The app shows ads from Google AdMob after you have finished three games, and Google's advertising software may collect some information about your device, as described below. We do not sell your data.

What the app stores on your device

The app stores the following in its own database on your iPhone: player names, games, rounds, rule presets and the statistics calculated from them. This information is not sent to us. Because it is part of the app's data, it is included in your iPhone backups (for example iCloud Backup or a backup made on a computer) in the way Apple handles any app's data.

You can also export a backup file from the app. It is a plain JSON file that you save wherever you choose, and you can restore from one later. Where you save it, and who can read it, is up to you.

No account and no developer server

You do not create an account. We operate no server that receives your names, games or scores, and the app contains no analytics software of our own.

Ads, and when they start

Nertz Score is supported by banner ads from Google AdMob. Ads appear only at the bottom of the start screen, the Scoreboard, History and Past Games. They never appear on the Enter Round, New Game or Settings screens, or in any sheet.

No ads, consent form or tracking prompt appear until you have finished three games. A game counts when it ends with at least one round, and ending a game early counts. After that, the app first shows Google's consent form where the law requires it, and then Apple's App Tracking Transparency prompt. If you buy Remove Ads, you will not see ads or these prompts.

What Google's advertising software may collect

The app includes the Google Mobile Ads SDK. When it is active, Google and its advertising partners may collect or receive information such as:

• Device identifiers, including the advertising identifier (IDFA) only if you allow tracking, and other device identifiers used for advertising and fraud prevention.
• Your approximate location, derived from your IP address.
• Ad interactions, such as ads shown and ads tapped.
• Diagnostics, such as crash and performance information about the ad software.

We do not give Google your player names, games or scores. Google acts under its own policies; see Google's Privacy Policy and how Google uses information from sites or apps that use our services.

Consent and tracking choices

• Consent form. Where the law requires it (for example in the European Economic Area and the United Kingdom), a consent form from Google appears first. You can review your choice any time with Privacy options in the app's Settings, which appears only where it is required.
• Tracking. iOS then asks whether the app may track you across other companies' apps and websites. If you decline, you still see ads, but they are not personalized. You can change this at any time in iOS Settings, under Privacy & Security, then Tracking.
• Ad personalization. You can also limit ad personalization in your Apple Account and device settings.

Purchases

The optional Remove Ads purchase is handled entirely by Apple. We do not see your payment details or your Apple Account. The app only learns from Apple whether the purchase has been made, so it can turn ads off. Restore Purchases in Settings asks Apple to confirm it again.

If you email support

The app can start a support email to support@nertzscore.app. The draft includes information about the app and your device, such as the app version, iOS version and device model, which you can see and edit before you send it. It never includes player names or scores. If you send an email, we receive your email address and what you write, and we use them only to reply to you. Support email is forwarded through Cloudflare Email Routing to the developer's mailbox.

Children

Nertz Score is not directed at children under 13, and we do not knowingly collect personal information from them. Ad content is limited to family-friendly categories.

Deleting your data

You can delete games or players inside the app. Deleting the app removes its database from your phone. Because we hold no copy of your data, there is nothing to delete on our side. Backup files you exported, and device backups, are yours to delete. To ask Google about data it may hold, use the links above.

Changes to this policy

If we change this policy, we will post the new version here and update the effective date above. If a change affects how ads or tracking work in the app, we will also say so in the app's update notes.
