Privacy · Nobu Kaizen games
What our games collect. Nothing.
Twin Stars, Slingshot, Harmonia, Lantern and Loom are Nobu Kaizen games for iPhone. Updated 3 October 2026.
In every game
Every game says it in Settings, under Privacy: “This game collects nothing. No account, no network, no tracking.”
None of the games contains networking code: nothing they hold leaves your device unless you send it yourself, as with a Loom tapestry from the share sheet. We checked the source and each game’s pre-release build for networking code, and found none.
There is no account, no sign-in, no analytics, no ad network and no tracking. Apple offers its own opt-in “Share With App Developers” setting; it is Apple’s, and we receive nothing through it unless you opt in there.
Because the games collect nothing, they collect nothing from children either.
Permissions and links
The games never ask for your camera, microphone, location, contacts or notifications. The one permission any game asks for is Loom’s, to add a picture to your photo library.
The links in Settings — Privacy policy, Help and, in Twin Stars, one link to XLEVATED — open outside the game; the game itself fetches nothing. Like any website, nobukaizen.com runs on a web host that keeps standard access logs: the address each request came from, its time and the browser.
On your device
Your progress and your settings stay on your device, in the game’s own storage, and the games never send them anywhere. Like any app’s data, they are part of your own device backup if you use one.
Settings → Reset progress erases a game’s progress. Anything you bought stays yours.
Buying an unlock
Twin Stars is free and has nothing to buy. Slingshot, Harmonia, Lantern and Loom each have one unlock.
Apple handles buying and restoring the unlock; what Apple collects when it does is Apple’s, under Apple’s privacy policy, not ours.
The game checks a purchase on your device — which unlock, and whether Apple verified it — and sends it nowhere.
Loom and your photos
When you tap Save as wallpaper, Loom opens the share sheet with the tapestry you made. If you choose Save Image there, the picture is added to your photo library.
Loom asks only to add photos, never to see your library. Its request reads: “Loom adds the tapestry you save to your photo library, so you can set it as your wallpaper.”
Anything else you do in the share sheet is your choice; Loom sends nothing on its own.
