Privacy Policy

Effective 17 September 2026 · applies to the RandoMath iOS app, version 2.0.0

RandoMath is a math duel game by Asgar Amrahov. You can play it without giving us a name, an email address, or any other personal detail. This policy explains the data the app does handle, why, and the choices you have.

You do not have to create an account

To play online, the app signs you in anonymously with Firebase Authentication. This produces a random identifier for your device. It is not linked to your Apple ID, your email, or your name, and we cannot use it to identify you as a person. It exists so the game knows which score in a match is yours and which row on the leaderboard is yours.

An anonymous identifier lives with the app installation, so deleting the app ends your connection to it and the rank cannot be restored afterwards.

Signing in with Apple, if you want to

You can link your player record to your Apple ID from the profile screen. It is optional and the game does not ask for it. Its only purpose is to let your rank and record survive a reinstall or a new phone.

If you use it, Apple tells us a stable identifier for you and, unless you hide it, an email address. We store the identifier so that signing in again finds the same player record. We do not use the email address for anything: we send no email, and there is no mailing list.

You can delete the account from the same screen — Profile → Delete account. That removes your player record, your rank and your leaderboard row, and it cannot be undone.

What the app stores about your play

• A display name we generate for you — a label such as User#1423. You do not enter it and it contains nothing about you.
• Your ladder record — your rank, your win count, your loss count, and the time you last played. This is what the leaderboard is built from.
• Live match state — while a duel is in progress, the questions and both players' scores are held on our server so that the two devices agree on what is happening. Finished matches are recorded so results can be settled.

What other players can see

The leaderboard is public to everyone using the app. It shows the generated display name and the rank of the players on it. Nothing else about you is shown to another player, and nothing you type is ever shared, because the game has no chat and no free-text input.

Advertising

RandoMath is free and shows ads through Google AdMob: a banner, an occasional full-screen ad between games, and an optional ad you can choose to watch. To show and measure ads, Google may process device information such as your IP address and device model. See how Google uses data from apps that use its services.

The app does not ask for permission to track you across other companies' apps and websites, and does not access your device's advertising identifier for that purpose.

Crash reports

The app includes Firebase Crashlytics, which sends us a report when the app crashes: the type of device, the iOS version, and where in the code the crash happened. We use these to fix the crash. They contain nothing you typed and nothing that identifies you.

Analytics

The app sends analytics events to Google Analytics for Firebase — which screen you opened, that a match started or ended, that an ad was shown. They are about what happens in the game, and they carry no name, no email address and nothing you typed, because the app has no free-text input at all. We use them to see which parts of the game are used and which are not.

Notifications

If you turn notifications on from the profile screen, iOS asks for your permission and the app registers a push token with Firebase Cloud Messaging so that a reminder can reach your device. Turning them off, in the app or in iOS Settings, stops it. The app never asks for this on its own.

What we never collect

No name you typed, no phone number, no contacts, no photos, no precise location, no microphone or camera access, and no free-text input of any kind. The only system permission the app ever asks for is notifications, and only when you ask it to.

The advertising and consent SDKs described above may use a coarse, city-level location derived from your IP address, and report their own performance data, to decide which ad to show. That happens inside Google's SDKs; the app does not ask iOS for your location and holds none.

Children

RandoMath is a competitive game for a general audience. It is not directed to children, it is not offered in the App Store's Kids category, and we do not knowingly collect information from children. If you believe a child has provided us with information, email us and we will remove it.

Where the data lives

The data above is held in Google Firebase (Firebase Authentication, Cloud Firestore and the Realtime Database), operating on our behalf. Google's handling of it is covered by the Firebase privacy documentation.

Deleting your data

Delete it yourself from inside the app: Profile → Delete account removes your player record, your rank and your leaderboard row for good.

Deleting the app instead stops any further data being sent but does not by itself remove a record already stored. If you have already removed the app, email us and we will delete it.

Changes

If this policy changes, the effective date above changes with it. Material changes will be described in the app's release notes.
