Letter Trail (com.rjappstudio.abcadventureskidsfunworld) is published by RJ App Studio.

What the app does

This app teaches the alphabet through letter tracing and fifteen mini-games, designed for children ages 3–6. It does not require account creation, sign-in, or any personal information to play.

Advertising

The app uses the Google Mobile Ads SDK (AdMob) to show interstitial and rewarded video ads only — never banner ads. All ad requests are made under Google's child-directed treatment and under-age-of-consent settings, with the maximum ad content rating set to “G”, so ads are served on a contextual basis only, with no behavioral or interest-based targeting. Google and its partners may process device and network information — including the Android advertising identifier — that is needed to deliver ads, prevent fraud, measure ad performance, and maintain the ads service.

Interstitial ads are limited to at most one per session, and only after a letter has been completed — never during a game or at app launch. The rewarded video ad is offered only inside the Parent Zone, which sits behind a Parent Gate (an addition problem a pre-reader cannot solve), so only an adult can choose to start one.

In-app purchases

This app does not offer any in-app purchases or subscriptions. There is no ad-removal purchase or any other paid feature.

On-device preferences and progress

The app stores a small amount of data locally on the device using Hive, an on-device storage library. This includes letter progress and mastery, sticker collection, day streak and days visited, and sound settings. This data stays on the device, is never transmitted anywhere, and is used only to remember the child's progress and preferences. A “reset progress” control in the Parent Zone erases all of it.

Device permissions

The app requests internet and network-state access (required to fetch ads), vibration (for touch feedback), and the advertising-identifier permission used by the Google Mobile Ads SDK. It does not request access to location, camera, microphone, contacts, photos, files, or the phone.

External links

The app does not open any external links or web pages during gameplay.

What the app does not do

• No account registration or sign-in
• No user-generated content or uploads
• No collection of names, email addresses, photos, voice recordings, location, or other personal information
• No analytics, crash-reporting, or tracking SDKs of any kind
• No biometric data collection
• No in-app purchases of any kind

Children's privacy

This app is designed and directed at children and is operated in accordance with the Children's Online Privacy Protection Act (COPPA), the GDPR provisions on children's data, and Google Play's Families Policy. It does not knowingly collect personal information from children. Advertising is limited to contextual, non-personalized ads served under Google's child-directed API settings, and controls that could affect a child's experience are protected by a Parent Gate. Parents or guardians should review this policy and supervise device use.
