The Yume Tower app itself does not collect or transmit personal data to us.
Last updated: 25 August 2026
Yume Tower itself doesn't collect anything. There are no accounts and no sign-in. The app doesn't use analytics or advertising, and it contains no third-party SDK that gathers information about you. The one exception is beta testing through TestFlight, described below, where Apple may share some information with us.
Saved games and settings are written to storage on your own device, and they are never uploaded anywhere. On iPad they are removed when you delete the app. On a Mac they stay in your Library folder until you remove them yourself.
If you have iCloud or device backups switched on, your saves may end up in those backups. Apple handles that under Apple's own privacy policy, and we have no access to it.
The full version is a one-time purchase, and Apple handles the payment through the App Store. We never see your payment details, your name or your address. What Apple gives us is anonymous sales figures.
During the beta the app is distributed through Apple's TestFlight, and TestFlight is the one case where information about you can reach us. While you use a TestFlight build, Apple may provide us with crash logs, basic device and usage information (such as device model, OS version and session counts), and any feedback or screenshots you choose to send. If you installed from a public TestFlight link, Apple does not give us your email address. All of this goes to Apple first, under Apple's own privacy policy, and we see only what Apple passes on. Sending crash reports and feedback is controlled by your own sharing settings, so whether to send them is up to you.
The app doesn't collect data from anyone, children included.
If a later version needs to collect something, we will update this page and the privacy information on the App Store before that version goes out, and we will say what changed.
