Privacy Policy

Effective November 5, 2026 · Applies to Holdout: Zombie Tower Defense (“Holdout”, shown as 死守 on Chinese-language devices) for iOS and Android, published by Lumiora Labs Inc. (“we”).

What the game stores, and where

To keep your progress, the game saves the following only on your device, in the app’s private storage:

• game progress: levels, records, unlocked towers, research, items, in-game credits and achievements;
• the commander name you choose (a random name is assigned at first launch);
• settings such as language, sound volume, graphics quality and vibration.

This data never leaves your device and we have no access to it. You can erase it at any time with Settings → Reset progress, or by deleting the app. Depending on your device settings, the operating system may include app data in your own device backups (for example iCloud or Google backups); those backups are governed by Apple’s or Google’s privacy policies, not ours.

What we do not do

• No accounts or sign-in, and no contact information is requested.
• No advertising and no advertising identifiers.
• No analytics, crash reporting or third-party tracking SDKs.
• No location, camera, microphone, contacts or photo access.
• No in-app purchases. The in-game credits and supply crates are earned by playing and cannot be bought with real money.
• The game does not need or use an internet connection to play.

Links that leave the game

The Privacy and Support buttons in Settings open this website in your browser. This website is static: it sets no cookies and runs no analytics. Our hosting provider may process standard technical data (such as IP address) to deliver the page securely.

Email

If you email us, we receive your email address and whatever you choose to write. We use it only to reply to you and delete it when it is no longer needed for that purpose.

Children

Holdout does not collect personal information from anyone, including children under 13.

Your rights

Because we hold no personal data about you from the game, there is nothing for us to access, correct or delete. For anything related to an email you sent us, contact us at the address below.

Changes

If a future version adds features that handle personal data (for example online play), we will update this policy and the App Store / Google Play privacy information before that version is released, and change the date above.
