Privacy Policy

The short version

Your game save stays on your device. There is no account, no login, no analytics, no tracking, and no ads. On iOS, RevenueCat processes an anonymous installation identifier and purchase status to validate and restore access. This service starts when the app opens, including when you have not bought anything.

What data do we collect?

The purchase service processes purchase history and status and an anonymous identifier that RevenueCat generates for your installation so access can be validated and restored.

We do not collect your name, email address, contacts, location, photos, browsing activity, or any usage or gameplay data. We do not collect crash reports. The anonymous identifier is created by the app; it is not your Apple ID, your advertising identifier, or anything that identifies you as a person. None of it is used for tracking, none of it is sold, and none of it is combined with data from other apps or companies.

The purchase service initializes when the iOS app starts. RevenueCat can process the anonymous installation identifier and check purchase status even if you do not buy anything.

Where is my game data stored?

Your save game is stored exclusively in your device's local storage (localStorage on web; via Capacitor on iOS). It never leaves your device and is not synced to any cloud service.

Uninstalling the app or clearing your browser's site data will erase the save. Use the Export save option in Settings to create a backup.

Third-party SDKs and services

There are no analytics SDKs, no advertising networks, no crash reporters and no social-login libraries. The third-party code in the app is:

• Capacitor — native iOS packaging. Sends nothing.
• Apple's StoreKit — takes the payment. Apple holds the purchase record under Apple's own policy.
• RevenueCat — validates purchases and makes them restorable across reinstalls. It receives your purchase history and the anonymous installation identifier described above, and acts as our data processor. Nothing about how you play is sent to it.
• Founding Owner access in version 1.4.0 is checked locally using Apple's verified original purchase. This version no longer sends the original app receipt to our former verification endpoint. Earlier versions may still attempt that request; the endpoint is unavailable.

In-app purchases

The app is free to download. Silicon Pro is available as an auto-renewing subscription (monthly or yearly, with a free trial) or as a one-time lifetime purchase. A legacy one-time Creative Mode unlock is still honoured for everyone who bought it.

We never see your payment details. Payment is handled entirely by Apple through StoreKit; card numbers and billing information never reach us or our processor. What we do receive is the fact of the purchase — which product, and whether it is still active — so the app knows what to unlock and can restore it if you reinstall or switch devices. Purchase records are also held by Apple under their Privacy Policy.

Subscriptions renew automatically unless cancelled at least 24 hours before the period ends; you can manage or cancel one at any time in your Apple ID subscription settings.

Children's privacy

Silicon is rated 4+ and is not directed at children specifically, but it is safe for them: there is no tracking, no advertising, no profiling, and no way for anyone to contact anyone else through the app. We do not knowingly collect personal information from children under 13, and the purchase data described above contains none.

Changes to this policy

We update the date above when this policy changes. The latest update clarifies purchase-service initialization and removal of the former original-purchase verification request in version 1.4.0.
