Privacy policy

This policy explains how the game and support website handle data. Contact smartgrow75@gmail.com with questions.

Data stored on your device

Levels, stars, puzzle state, hint usage, language, sound, vibration, motion preferences, and an age band are stored locally. The game does not ask for a date of birth, name, email, or account to play. There is no cloud sync for progress.

Clearing app data in Android settings deletes local progress. This does not establish deletion of information already processed by Google services.

Ads and privacy choices

The game uses Google AdMob and UMP. It does not request ads before an age band or “Prefer not to answer” is selected. Each level has a limited free hint allowance; an additional hint can be earned through an optional rewarded ad when available. Opening or closing an ad alone does not grant a hint.

Adults receive applicable consent choices when needed. Ad privacy options appear in game settings when required by UMP. Ad personalization is disabled and maximum ad content rating is G for all age groups.

Google services

When ad services are used, Google may process IP addresses suggesting a general region, ad interactions, performance diagnostics, and certain device or account identifiers depending on settings. These support advertising, measurement, and fraud prevention. The SDK encrypts data in transit.

The Android advertising ID permission and ad-services identifier permissions are removed. This does not mean Google services process no other data. The game does not request location, camera, or microphone permissions, and integrates no additional ad networks or standalone analytics SDK.

Google’s policies govern its processing and retention. See https://policies.google.com/privacy Google’s privacy policy and https://developers.google.com/admob/android/privacy/play-data-disclosure the ads SDK data disclosure.

Optional Google Play Games achievements

When a Play Games connection is available, adults can choose to connect their Google gaming profile to view legitimately earned achievements. Google services may process the gaming-profile identity, achievement activity and technical connection data. The game does not request your Google email/password or Drive access. Connection is optional; play, stars and hints remain stored locally without it. Achievement connection does not enable cloud saving of puzzle progress and is unavailable to children or unspecified ages.

Children and age selection

The intended audience is ages 6 and up, including children and adults. The age screen stores a band locally without collecting a birth date or defaulting to adult. “Prefer not to answer” permits access to the same game.

Every under-18 or unspecified player receives child-directed ad treatment. UMP is tagged as under the age of consent to avoid requesting adult consent from restricted players. There is no player chat, content sharing, or in-app purchasing.

Production ads for minors and unspecified ages are disabled pending verification of Families ad-format requirements. Free hints and gameplay remain available. This policy will be updated when ad behavior changes.

This website and support email

This page has no registration forms, tracking cookies, analytics tools, or ads. Hosting infrastructure may process connection information such as IP addresses to deliver and protect the page. If you email us, we receive your sender address and the information you choose to share, for replying and following up. Email is not required to play.

Please do not send sensitive information or a child’s personal details. A parent or guardian should contact us about children’s data requests.

Requests and updates

For questions or assistance accessing or deleting support correspondence, contact smartgrow75@gmail.com. Requests are handled according to available information and applicable requirements. We do not hold a cloud copy of game progress and cannot recover deleted local saves.

This policy may change as features or services change. The update date appears above.

Active play time and result statistics are stored on your device and are not an IQ test. Occasional ad breaks may appear after level results, not during a puzzle. Availability depends on your age/privacy choices and ad readiness. No hint is granted without the rewarded ad earned event.
