Privacy Policy

Overview

Silent Killer: Hoistway Havoc ("the Game") is a mobile arcade game developed by Joshua Worth. This privacy policy explains how we handle information when you use our Game.

Information We Do NOT Collect

The Game does not collect:

• Personal information (name, email, phone number, address)
• Location data
• Usage analytics of our own (we run no analytics service and no server)
• Photos, contacts, or other device data

Local Data Storage

The Game stores the following data locally on your device only:

• Game progress and high scores
• Game settings (audio preferences, display settings)
• Unlocked content and achievements

These local records stay on your device. If you use the optional platform services below, the Game also submits scores and achievements to that platform. The Amazon edition stores the app-specific Amazon user ID and whether that user owns the ad-free purchase in local app storage. You can delete local data by uninstalling the Game or clearing the app's data through your device settings.

Third-Party Services

The Game integrates with the following optional platform services:

• Apple Game Center (iOS): If you choose to sign in, Game Center handles leaderboards and achievements according to Apple's Privacy Policy.
• Google Play Games (Google Play edition only): If you choose to sign in, Play Games handles leaderboards and achievements according to Google's Privacy Policy.

Using these services is entirely optional. The Game functions fully without signing into either platform. The Amazon edition does not use Google Play Games.

Purchases

The one-time "Go Ad-Free" purchase is handled by the store where you obtained the Game: Apple, Google Play, or the Amazon Appstore. We do not receive your payment details.

In the Amazon edition, Amazon's purchasing SDK provides an app-specific Amazon user ID, product ID, receipt IDs, and purchase or cancellation status. The Game uses these locally to confirm ad-free ownership, restore purchases for the current Amazon account, and remove ad-free access after a refund or cancellation. The SDK communicates with Amazon to retrieve purchase history and confirm fulfillment. We do not send these purchase identifiers to a developer-operated server. Amazon handles this information under Amazon's Privacy Notice.

Children's Privacy

The Game is not directed at children. It is rated for players aged 13 and over, it is not part of any children's program on any store, and we do not knowingly collect personal information from anyone, including children under 13. If you believe a child under 13 has used the Game and you want the advertising identifier associated with that device cleared, use the device controls listed under Advertising, or contact us and we will help.

Advertising

The Game shows banner, interstitial and rewarded ads. Ads are served through Unity LevelPlay mediation, which passes each ad request on to whichever ad network wins it. The networks enabled in the Game are Unity Ads, AppLovin, Vungle (Liftoff), Meta Audience Network, Mintegral and Pangle.

To select and measure ads, those companies receive:

• your device's advertising identifier (the Advertising ID on Android, the IDFA on iOS, and only if you allow tracking when iOS asks);
• coarse technical information about your device, such as model, operating system version, language and general region;
• which ads were requested, shown, tapped or completed.

We do not receive any of that data ourselves. It goes from your device to the ad networks. Each network publishes its own privacy policy, and you can limit what they receive with your device's own controls: on Android, Settings > Privacy > Ads > Delete advertising ID; on iOS, Settings > Privacy & Security > Tracking.

The Game asks for tracking permission on iOS. Declining is fine: the Game still works and still shows ads, they are just less relevant.

Versions released before 2.9.0 served ads through Google AdMob instead of Unity LevelPlay. If you are running one of those builds, the company receiving your advertising identifier and the technical information above is Google, under Google's Privacy Policy. Everything else in this section, including the device controls and the ad-free purchase, applies the same way.

Changes to This Policy

We may update this privacy policy from time to time. Any changes will be posted on this page with an updated revision date. We encourage you to review this policy periodically.
