Anurag Purwar Privacy Policy

Effective 5 November 2026 · Anurag Purwar

This policy covers every Android app published on Google Play under the developer name Anurag Purwar. The apps are made and published by Anurag Purwar, an individual developer, who is responsible for them and for this policy ("we" and "us" below). It covers these apps:

GameHub holds all the games; each of the others from Ludo to Word Finder is one of its games as an app of its own. Together these are called "the game apps" below. Kids Learning is learning activities and drawing for children aged 3 to 10.

In short: no app asks who you are, has accounts, or sells your personal information. The apps show ads from Google AdMob, which are set up for children: they are not personalised and do not use the advertising ID. The game apps all handle information the same way. Every app also sends anonymous usage counts and crash reports, as described under "Usage counts and crash reports".

What stays on your device

Each app saves what you need to carry on where you left off, in its own private storage on your phone:

• in the game apps: an unfinished game; your game stats (games played, wins, losses and draws, streaks, best scores); your Sudoku progress; and whether you have seen each game's rules;
• in Kids Learning: the age group chosen, which activities are finished, the coins earned, and the child's drawings (never sent anywhere);
• extra levels or activities already downloaded.

This information is never sent to us or anyone else. It is removed when you clear the app's storage or uninstall the app.

When GameHub and one of its games' own apps are both on the same phone, each can read the other's game stats, Sudoku levels solved and best scores (2048, Block Puzzle, Block Drop and Snake Trail), so they show in both. It keeps a copy of the levels and best scores; stats are only shown, not copied. Unfinished games are not shared. Nothing leaves the phone for this, and only our own apps can read it.

What goes over the internet

Every app uses the internet to show ads. Some apps also download extra content: Sudoku level packs in GameHub and Sudoku, and extra activities in Kids Learning.

Each app also asks Google Play, when it opens, whether a newer version is out. When one is, the app reads its update settings, which say whether this version must update before it can be played, and Google Play downloads and installs the update.

Extra content and update settings come from Google Cloud Firestore, part of Google's Firebase platform. These downloads contain no information about you, your games or your progress.

As with any connection to an online service, Google's servers see your device's IP address. The Firebase software in the apps also sends basic technical details with each request: the device model, the Android version, the app store that installed the app, and the versions of the Firebase software. Google states that these details are not linked to a user or device identifier. Google handles this data as a service provider under the Firebase privacy and security terms. All downloads use an encrypted (HTTPS) connection.

Usage counts and crash reports

The game apps use Google Analytics for Firebase to count how they are used, so we can see which games are played and which are too hard. They count two things: each screen opened, and each game finished (which game, whether it was against the computer, at which level, and whether it was won, lost or drawn; for Sudoku, the level and the hints used). Nothing that names the player is sent.

Kids Learning uses Google Analytics for Firebase to count how the app is used, so we can see which activities work and which are too hard. It counts six things: the age group chosen, an activity started, a hint used and the step-by-step guide opened (each with whether it needed a video), a video that could not be found (with the ads software's technical reason), and an activity finished (with the hints used and coins earned). Nothing typed, said or drawn by the child is sent, and nothing that names them.

Kids Learning reads its questions aloud with the phone's own text-to-speech. The app sends no text or sound anywhere for this.

Every app uses Firebase Crashlytics to send us a report when it crashes: what went wrong in the code, the device model, the Android version and the app version.

Both tools use a random number that identifies this installation of the app, not the person or the device. It changes when the app's storage is cleared or the app is reinstalled. The advertising ID and the Android ID are not collected, and Analytics data is not used for ads. Analytics also learns which store or link installed the app. Debug builds made for testing send neither. Google processes this data for us under the Firebase privacy and security terms.

Ads

The apps show ads from Google AdMob. A short video plays only when you choose to watch one, for example for an extra hint or an extra undo; in Kids Learning, when the child taps a button marked as a video (a video hint, or the guide a second time on the same question). The game apps also show a full-screen ad at most once every three finished games, as you leave the result screen. Kids Learning never shows a full-screen ad; it shows a small banner on its Well Done screen and at the foot of its activities list, away from the answers. No ad appears in the middle of a game, and none beside the answers in an activity.

Every ad request is marked as coming from a child and asks for ads suitable for general audiences (rated G). Under Google Play's Families policy this means the ads are not personalised, there is no remarketing or interest-based advertising, and the advertising ID is not used (the apps do not ask Android for it).

To show and count ads and to prevent fraud, the AdMob software sends Google your device's IP address, technical details such as the device model, Android version and app version, and how you interacted with the ad (for example, whether it was shown or tapped). These connections are encrypted. Google's use of this information is described in How Google uses information from sites or apps that use our services.

What the apps do not do

• No sign-in or account, and no request for your name, email or phone number.
• No personalised ads, and no use of the advertising ID.
• No tracking across other apps or websites.
• No in-app purchases.
• No access to your location, contacts, camera, microphone, photos or files.
• No selling of personal information, and no sharing beyond what is described above.

Permissions

Each app asks Android for internet access and to check whether a network connection is available, for loading ads and downloads, and to keep the device awake briefly while the ads software finishes its work. Each app also asks Google Play which store or link installed it, for its usage counts. None of these shows a permission prompt.

Children

The game apps are made for everyone, including children under 13, and Kids Learning is made for children. No app asks anyone for personal information. Ads follow Google Play's Families policy as described under Ads: they are not personalised, are rated for general audiences, and do not use the advertising ID.

Keeping and deleting data

Everything an app saves is on your device, and you can remove it at any time from Android's app settings (Storage → Clear storage) or by uninstalling the app.

The usage counts and crash reports are kept by Google for us for a limited time and then deleted automatically. Because they are not linked to a name or account, we cannot pick out one person's records; clearing the app's storage starts a new random number, so nothing new is linked to the old records. To ask about this data, write to the address below.

Changes to this policy

If the apps' handling of information changes, this page will be updated and the effective date above will change.
