Data Minimization & Trust

Rule Sort does not require sign-up and has no account system of its own — it does not send your gameplay data to our servers. The outside services Rule Sort talks to are Google Firebase (anonymous gameplay analytics, app stability and remote settings), Google AdMob (to show the ads that keep the game free), AppsFlyer (to measure which ad campaign brought an install), GameAnalytics (to see how long players keep playing), the App Store (for Remove Ads) and, only if you open the leaderboard, Apple Game Center.

What Data Do We Collect?

Gameplay progress: your best scores, streaks, and sound settings are stored only on your device (via Apple's standard on-device storage). We never see or receive this data — it stays on your phone or tablet.

Leaderboard (optional): if you view or submit to the online leaderboard, it runs entirely on Apple Game Center, which is tied to your Apple ID — this is Apple's own account system, not one Rule Sort creates or manages. We do not operate this feature ourselves and never see your Game Center identity — it is governed by Apple's Privacy Policy.

Anonymous gameplay analytics: Rule Sort uses Firebase Analytics to log gameplay events — for example that a run started or ended (with its score), or that a revive was offered or used. These events are tied to a random app-instance identifier, not to your name, email or any account, and are used only to understand how the game is played and to tune it. Firebase Remote Config delivers those settings to the app.

Crash and performance data: Rule Sort uses Firebase Crashlytics and Firebase Performance to detect crashes and slow-downs. This can include device and app diagnostic information, but never your personal information.

Advertising data: Rule Sort shows ads through Google AdMob. AdMob and its partners may process device and advertising identifiers, approximate location derived from your IP address, and ad interaction data to serve and measure ads — see "Advertising & Tracking" below.

Install measurement: Rule Sort uses AppsFlyer to learn which ad campaign, if any, led to your install, together with a few game events — a run started or ended (with its score and length), a first finished run, a new mode opened, a rewarded ad watched, a purchase made — and the revenue from the ads shown. This uses a device identifier, and your advertising identifier only if you allow tracking. It is not linked to your name, email or any account.

Gameplay analytics: Rule Sort uses GameAnalytics to understand how the game is played — sessions and their length, runs started and finished (with score and length), modes opened, rewarded ads watched, ads shown and purchases — along with device model, OS and app version, approximate country, crash and performance data. This uses a random ID that GameAnalytics creates for your install, a device identifier, and your advertising identifier only if you allow tracking. It is not linked to your name, email or any account.

Purchases: Remove Ads is bought through the App Store. We learn that it was bought so we can deliver it; we never see your payment details.

Notifications: Rule Sort schedules a daily puzzle reminder on your device only; iOS delivers it quietly to Notification Center unless you choose otherwise. You can turn it off in the iPhone Settings app at any time.

Advertising & Tracking

Rule Sort uses Google AdMob, which may work with mediation partners such as Unity Ads and InMobi, to show optional rewarded ads (for example, to continue a run after losing) and occasional full-screen ads between runs. Buying Remove Ads turns off the full-screen ads and makes revives free.

When the game first starts, iOS asks whether Rule Sort may track you across other companies' apps and websites. If you allow it, your device's advertising identifier is used to show you more relevant ads and to measure which ad campaign brought your install; if you decline, you still see ads — they are just not personalized — and the identifier is not used for install measurement either. You can change this at any time in iOS Settings → Privacy & Security → Tracking.

In the European Economic Area, the UK and Switzerland you are first asked for consent through Google's consent form. You can change your choice at any time in the game under Settings › Privacy Options; it applies to AppsFlyer too.

See Google's Privacy Policy, Unity's Privacy Policy and AppsFlyer's Privacy Policy for how these partners process advertising and install data.

Children's Privacy

Rule Sort is a general-audience game, not an app specifically directed at children, and it has no account system of any kind — so we do not knowingly collect personal information from anyone, including children. Parents should note that Rule Sort displays third-party ads (see above) and may want to review the App Tracking Transparency setting on a child's device.

Third-Party Services

Rule Sort relies on the following outside services:

• Google AdMob and its mediation partners (such as Unity Ads and InMobi): the rewarded and full-screen ads described above.
• AppsFlyer: install measurement — which ad campaign, if any, brought an install — as described above.
• GameAnalytics: gameplay analytics and retention, as described above. See GameAnalytics' Privacy Policy.
• Apple App Store: the Remove Ads purchase.
• Google Firebase (Analytics, Crashlytics, Performance, Remote Config): anonymous gameplay analytics, crash reporting, performance monitoring and remotely tuned game settings.
• Apple Game Center: powers the optional online leaderboard, entirely under Apple's own systems and privacy policy.

Data Retention and Your Rights

Because Rule Sort has no accounts and no server-side user database, we hold no personal data of yours to retain or delete. On-device data (scores, settings) is removed the moment you delete the app. For Game Center data, contact Apple directly. For advertising identifiers, use iOS Settings → Privacy & Security → Tracking to reset or limit ad tracking at any time. Firebase data is not linked to your identity and is kept under Google's standard Firebase retention settings, AppsFlyer data under AppsFlyer's own retention policy, and GameAnalytics data under GameAnalytics' own retention policy.

Policy Updates

If this policy changes, we will update the "Last updated" date above. Continued use of Rule Sort after a change means you accept the updated policy.
