Last updated: October 21, 2026 · Redstone Logic for Android (app.redstonelogic.circuits)
Redstone Logic ("the App") is a redstone circuit designer and simulator, operated by Swap Widget LLC ("we"). If you have any questions about this policy, email swapwidget@gmail.com.
Your circuits, their names and the App's settings are stored in the App's private storage on your phone. Redstone Logic has no sign-in and no cloud sync of its own, and none of this is ever sent to us.
Files you save. When you export a circuit (as a Redstone Logic file, or as a structure file or schematic for your world), the App writes it wherever you choose through Android's file picker, such as your phone's storage or a cloud drive. Import reads a file only when you pick it. We never receive these files. If you save one to a cloud service, that service's privacy policy applies to the copy.
Android device backup. Android's own backup may copy the App's data to your Google account, as it does for most apps. You control that in your phone's settings.
Only when you choose to. Support & feedback (on the home screen and in the editor's menu) lets you send us a bug report, a feature request or a question. When you tap Send, the App sends your message, its type, the App's version and your Android version to our server at api.swapwidget.com, run by Swap Widget LLC. Nothing is sent unless you tap Send, and no circuits or contact details go with it.
A random ID instead of an account. The first time you use that page, the App makes a random code on your phone. It's sent with your messages so you can see your own requests and our replies, and our server keeps only a scrambled (hashed) form of it. It isn't linked to your name, email or Google account. Uninstalling the App or clearing its data makes a new one.
The public updates log. When we reply to a request or start work on it, the request and our reply appear in the App's Updates log, which everyone using Redstone Logic can see, without your name and with only a short piece of the random ID. Please don't put personal details in a message.
Redstone Logic is a one-time purchase, not a subscription, handled entirely by Google Play. Google processes the payment; we never see your card or payment details, and the App has no ads and no in-app purchases. Google Play's terms and the Google Privacy Policy apply to the purchase.
Apart from support messages you choose to send, we hold no data about you, so there's nothing else for us to hand over or delete on our side. If you have a question or request about your privacy, email us and we'll help.
Your circuits are protected by Android's app sandbox on your device. Support messages travel to our server over an encrypted connection. Keep exported files somewhere you trust, since anyone with a copy can open them.
Redstone Logic is intended for people aged 13 and over and is not directed at children under 13. We don't knowingly collect personal information from children.
If this policy changes, we'll update the date at the top and publish the new version at this address. Significant changes will also be mentioned in the App's release notes.
