Nertz: Solitaire Card Game — Privacy Policy

Effective Date: October 4, 2026

Nertz: Solitaire Card Game ("the App") is developed by Mobile Card Games & Travel Apps LLC for iPhone and iPad (App Store) and Android (Google Play). This Privacy Policy explains what data the App collects, how it is used, and how your privacy is protected.

1. Data We Collect

Nertz works without an account — you never give us your name, email, or any contact information. Your game statistics, settings, and any match in progress are stored on your device. The free version shows ads from Google; online play (iPhone and iPad only) uses Apple Game Center, and leaderboards and achievements use Apple Game Center on iPhone and iPad or Google Play Games on Android. Those services receive the device-level data described below.

Advertising data (free version only): ad request, impression, and click data plus device information, sent to Google AdMob when an ad is loaded. On Android this can include your device’s advertising ID and app set ID. Nertz Pro removes all ads.
Ad consent choices: where the law requires it (for example in the EEA, the UK, and Switzerland), Google’s User Messaging Platform asks for your consent and stores your choice on your device.
Game Center data (iPhone and iPad): if you sign in to Game Center, your Game Center player ID, display name, scores, and achievements are handled by Apple. In online matches, the other players see your Game Center display name, and your moves are exchanged with them through Game Center.
Google Play Games data (Android): if you use Google Play Games, your Play Games player ID, gamer profile name, submitted scores, and achievements are handled by Google. The Android version has no online play.
Your table name: the name you choose for bot matches is stored only on your device.
Purchase information: Nertz Pro is bought through Apple’s StoreKit on iPhone and iPad or Google Play Billing on Android; we never see your payment details.

2. How We Use Your Data

Ads fund the free version; Apple Game Center powers online matches (iPhone and iPad), Game Center or Google Play Games powers leaderboards and achievements, and your on-device statistics power the Stats screen. We do not use any of it to identify you personally. The app contains no analytics or crash-reporting software on either platform.

3. Advertising

The free version shows ads between rounds and optional rewarded video ads, served by Google AdMob. Ads are never shown during a round. When an ad is requested, Google receives device information, ad interaction data (requests, impressions, clicks), and your approximate location as derived from your IP address. Ads are requested only after Google’s User Messaging Platform has collected any consent your region requires, and you can change that choice at any time in Settings > Ad Privacy Choices (shown where required).

iPhone and iPad: the app does not request App Tracking Transparency permission, so Google does not receive Apple’s advertising identifier (IDFA) from this app for cross-app tracking. Ad-campaign results are measured using Apple’s privacy-preserving SKAdNetwork system, which reports conversions without identifying individual users.

Android: the Google Mobile Ads SDK may use your device’s Android advertising ID and app set ID. You can reset or delete your advertising ID at any time in Android Settings > Privacy > Ads.

How Google uses advertising data is described in the Google privacy policy.

4. Third-Party Data Sharing

Each service the app uses, and what it receives:

Google AdMob and User Messaging Platform (privacy policy): ad request, impression, and click data, device information (on Android including the advertising ID and app set ID), IP-derived approximate location, and your ad-consent status, as described in the Advertising section. Not used if you have Nertz Pro.
Apple Game Center (iPhone and iPad; Apple privacy policy): your Game Center player ID, display name, submitted scores (match wins, best round, fastest Nertz), and achievements; in online matches, your display name and in-game moves are relayed by Apple to the other players in that match.
Google Play Games (Android; Google privacy policy): your Play Games player ID, gamer profile name, submitted scores (match wins, best round, fastest Nertz), and achievements.
Apple: in-app purchases through StoreKit, and iCloud key-value storage for remembering your Nertz Pro unlock (see below).
Google Play: in-app purchases through Google Play Billing; Google Play also restores your Nertz Pro unlock on Android.

We do not sell your data, and we share nothing beyond what each service above requires to function.

5. Data Storage and Retention

On your device: statistics, settings, your table name, and any match in progress.
In your iCloud account (iPhone and iPad): whether you have unlocked Nertz Pro is synced across your devices via Apple iCloud key-value storage tied to your Apple ID; we cannot access it.
In your Google account (Android): if Android backup is turned on, your settings, statistics, and any saved match are included in Android’s automatic app backup, which Google encrypts and stores in your Google account; we cannot access it. Your Nertz Pro unlock is restored from Google Play itself.
On third-party servers: Google holds advertising data under its own retention policies; Apple holds Game Center and App Store purchase records; Google holds Play Games and Google Play purchase records.
We operate no servers of our own and hold no copy of your data.
Deletion: uninstalling the app removes all locally stored data.

6. Data Security

All communication with Google and Apple takes place over encrypted (HTTPS/TLS) connections. Since the app collects no name, email, or account credentials, there is no such data to secure or breach on our side.

7. Your Rights

You can:

Change or withdraw your ad consent in Settings > Ad Privacy Choices (shown in regions where it is required).
On Android, reset or delete your advertising ID in Android Settings > Privacy > Ads.
Remove ads entirely with Nertz Pro.
Play without Game Center or Google Play Games; online play (iPhone and iPad), leaderboards, and achievements are optional.
Remove all locally stored data by uninstalling the app.

Depending on where you live, privacy laws such as the European Union's General Data Protection Regulation (GDPR) and the California Consumer Privacy Act as amended by the California Privacy Rights Act (CCPA/CPRA) give you rights over your personal data, including the rights to know, access, correct, and delete it. Because we do not hold your data on servers we operate, there is typically nothing for us to access or delete on request — deleting the App deletes your data. Where the App does process data in transit, or a third-party service described above collects data, you may contact us at the email below to exercise your rights, and we will respond as required by applicable law.

8. Children's Privacy

The App is not directed at children under 13, and we do not knowingly collect data from children under 13. In some regions, including the European Union, a higher minimum age applies to consent for data processing; the same statement applies there — we do not knowingly collect data from anyone under the applicable age.

9. Data Breach Notification

In the unlikely event of a data breach affecting user data on any system we operate, we will notify affected users as required by applicable law.

10. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be reflected by updating the "Effective Date" at the top of this page.
