Privacy Policy

Effective 20 August 2026

Gravity Stack is provided by Kobyzada Games. This policy explains how information is handled when you use the game.

Information processed

Gravity Stack stores gameplay preferences, rescue balance, and local high-score information on your device. If you choose Google Play Games sign-in, Google may process your Play Games profile identifier, player name, and scores so authentication and leaderboards work. The game does not receive or store your Google password.

If you choose to watch a rewarded advertisement, Google Mobile Ads may process device identifiers, advertising identifiers where permitted, approximate location derived from network information, ad interactions, diagnostics, and consent choices to provide, measure, secure, and improve advertising. Rewarded advertisements are optional.

If you make an in-app purchase, Google Play processes payment and purchase information. Gravity Stack receives purchase status and product-entitlement information so purchased rescues can be granted. The developer does not receive your full payment-card details.

Purposes

Information is used to operate the game, save preferences, authenticate optional Play Games features, publish leaderboard scores, provide optional rewarded advertisements, fulfil purchases, prevent fraud, diagnose failures, and comply with legal obligations.

Sharing and service providers

Information may be processed by Google as provider of Google Play, Play Games Services, Google Play Billing, and Google Mobile Ads. Google’s handling of information is governed by its own privacy policies and product terms. Gravity Stack does not sell personal information.

Children

Gravity Stack is intended for players aged 13 and older and is not directed to children under 13. Age-related consent and advertising requirements are applied where required by law and platform policy.

Retention and deletion

Local game data remains on the device until app data is cleared or the game is uninstalled. Purchase records and Play Games data may be retained by Google under Google’s policies and legal obligations. See the data-deletion page for available steps.

Security

Reasonable technical measures are used to protect information. No method of electronic storage or transmission is completely secure.

Your choices

You can play without Google Play Games sign-in. Rewarded ads are optional. You can manage advertising and Google account settings through Android and your Google account, and clear local game data through Android settings.

Changes

This policy may be updated when the game, service providers, or legal requirements change. The effective date above identifies the current version.
