Quiet Universe works without an account. Game Center progress sync is optional. Eligible free players may choose to watch a rewarded advertisement to unlock game content; ads never interrupt a puzzle automatically.
The app stores puzzle progress, downloaded levels, settings, and purchase entitlements on your device. Anonymous players use a random installation identifier. If you enable Game Center sync, our service stores a one-way digest of the verified Game Center player identifier and links progress and engagement events across your devices. We never send your Game Center alias, avatar, email, friends, or Apple ID to Railway. We record puzzle events and distinguish downloads you request from automatic background prefetches.
Google AdMob provides optional rewarded ads. The app requests non-personalized ads, does not request App Tracking Transparency permission, disables Google's publisher first-party identifier, and does not send your puzzle content, name, email, or Game Center identity to Google. Google and participating ad providers may nevertheless process device and app information, approximate location derived from an IP address, consent choices, ad interactions, diagnostics, and fraud-prevention signals to select, deliver, measure, and secure ads. Apple's SKAdNetwork may provide privacy-preserving install attribution without exposing the advertising identifier to the app. A random reward-attempt identifier is attached to a completed ad so our service can verify the reward; it is not an account identifier. You can review available consent choices from “Privacy & ad choices” in the app.
In-app purchases are processed by Apple. We receive entitlement and transaction information needed to provide Premium access, but not your full payment-card details.
Railway hosts the content, progress, and reward-verification service and may process technical request metadata needed to secure and operate it, such as IP addresses and request logs. Google provides consent and advertising services. Puzzle, download, rewarded-attempt, safety-report, and revenue-reconciliation records are retained while the service operates or until they are no longer needed for the purposes described here, subject to fraud-prevention, accounting, and legal requirements.
You can play included offline content without Game Center. Authenticated players can delete cloud progress and associated analytics events in the app. Deleting the app clears local data but does not itself delete cloud data. For questions, contact info@stuhr.biz.
We may update this policy when the app or its services change. The effective date above will identify the current version.
