Privacy policy
Nerovyn Block Puzzle is provided by Aleksandar Rankovic, operating under the Nerovyn brand in Montenegro. For privacy requests, contact nerovyngames@gmail.com.
Playing and local game data
You can play as a guest. Your chosen player name, avatar, scores, progress, coins, gems, saved power-ups and preferences are stored on your device. This version does not upload that progress to a cloud save or online leaderboard. Coins and gems are game items; this version does not offer purchases with real money or collect payment-card details.
Optional Google sign-in
If you choose Google sign-in, Google and Firebase Authentication process your account identifier, name and email to create and maintain your game account. We do not receive your Google password. Authentication services may also process IP addresses, device or browser information and security logs to operate the service and prevent abuse. Signing out does not delete the game account or your local progress.
Advertisements and privacy choices
The game integrates Google AdMob and Google's User Messaging Platform. Advertising services may process IP addresses (including approximate location), advertising or other device identifiers, app interactions and diagnostic information to deliver and measure advertisements and prevent fraud. Optional reward videos grant a power-up only after the advertising service confirms the reward. Ads between rounds appear at breaks in gameplay.
Where required, the app requests your advertising privacy choice before requesting ads. Where available, you can reopen the consent controls from Settings → Ad privacy options. Ad availability depends on your connection, privacy choices and the advertising service. Guest play may still involve advertising data; choosing guest mode is not an advertising opt-out.
Advertising is currently being tested; test ads do not generate revenue for the developer. The same SDK privacy considerations apply during testing. Non-personalised ads can still process technical information.
Why information is processed
We use account information to provide the optional sign-in service, local data to operate and personalise gameplay, and limited service information to protect the app against misuse. Advertising data is processed for advertising, measurement and security, with consent where required. You may withdraw an advertising consent through the available privacy controls.
Service providers
Google provides Google sign-in, Firebase Authentication, AdMob and consent-management services. They may process data outside your country under their applicable safeguards and terms. Learn more from Google's privacy policy, Firebase privacy and security information and Google advertising information. The developer does not sell your game profile to other businesses.
Retention and deletion
Local progress remains on your device until you reset it, clear the app's storage or uninstall it, subject to any backups controlled by your device. Your Firebase game account remains until deleted. In the updated app, Profile → Account & data → Delete game account asks for confirmation and a fresh Google sign-in; after Firebase confirms deletion, it removes your game account and clears the local game profile, progress, scores, currencies, power-ups and settings on that device. This does not delete your Google account. Other devices or device backups must be cleared separately.
You can also request account deletion by email without installing the app. After verifying account ownership, we aim to complete email requests within 30 days. We do not maintain a separate cloud copy of your game progress. Service providers may retain limited records for security, fraud prevention or legal obligations under their own retention policies; deleting the Firebase account does not automatically erase independently held advertising logs.
Your choices and requests
You may ask to access, correct or delete personal information associated with your game account by contacting us. You can change your local display name and avatar in the app. You can play without Google sign-in, sign out, delete the game account, reset local game data or change available advertising privacy choices. Depending on where you live, you may have additional rights to object, restrict processing or complain to a data-protection authority.
Age audience
This release is intended for people aged 13 and over, and is not directed at children under 13. Where local law requires a parent's or guardian's permission, it should be obtained before using an account or giving consent. If you believe a child under 13 has supplied personal information through the game, contact us so we can investigate and arrange deletion.
Permissions and changes
The game uses an internet connection for sign-in and advertisements. It does not provide features that access your camera, microphone, contacts or precise GPS location. We will update this page when data handling or features change, including if purchases, cloud saving or online leaderboards are added.
