Privacy Policy
Koi Drift has no accounts. You never give us your name, email address or any login. This page says exactly what the game keeps, what it sends, and why — on the web, in the Android app and in the iPhone app.
What stays on your device
Your progress — ponds cleared, cards earned, coins, settings, language, whether you own the Drifter’s Pass — is stored in your browser’s or the app’s local storage on your device. It is not uploaded. If you clear the site’s data or uninstall the app, it is gone; there is no server copy to restore from.
What the game sends to us
Gameplay statistics
The game records simple events — “pond cleared”, “hint used”, “app opened” — with a timestamp and sends them in batches to a server we run on Cloudflare. To tell one device’s events from another’s, the game makes up a random identifier the first time it runs and stores it on your device. That identifier is not linked to you, your phone, your account with anyone, or any advertising identifier. We use these statistics to see which ponds are too hard, which features are used, and whether an update broke something.
The Daily ranking
When you clear the Daily, the game sends the date, your time and your number of moves to the same server so it can tell you how you rank against other players that day. No name is attached; the ranking shows a position and a percentage, not who you are.
Purchases
If you buy the Drifter’s Pass in the Android app, the purchase is made through Google Play. Google handles payment; we never see your card or bank details. The app sends the purchase token Google issues to our server so it can confirm with Google that the purchase is genuine, and our server returns a signed confirmation to the app. We keep no purchase history beyond what Google Play itself keeps.
If you buy the Drifter’s Pass in the iPhone app, the purchase is made through Apple’s App Store. Apple handles payment; we never see your card or bank details. The app checks ownership with the App Store on your device; nothing about the purchase is sent to our server, and we keep no purchase history beyond what Apple itself keeps. Refunds for the iPhone app are handled by Apple under its own rules.
Saving a card to Photos (iPhone and Android)
When you choose to save the Daily card, the app asks for permission to add pictures to your photo library and writes the picture into a “Koi Drift” album. It does not read your other photos.
Advertising
In the Android and iPhone apps
The apps show advertising from Google AdMob in two places: a rewarded video that you choose to watch for a second chance or double coins, and an occasional interstitial advertisement between journey ponds once you are past pond 10 (never during a pond, and never in the Daily, the tutorial or Calm Drift). To do that, the Google Mobile Ads SDK runs in the app and may collect your device’s advertising identifier, an app-bound device identifier, your IP address, which advertisements were shown, and crash and performance data, as described in Google’s privacy policy. On Android you can reset or limit the advertising identifier in Settings. On iPhone the app never asks for permission to track you, so Apple’s advertising identifier is not available to the ads SDK and the advertisements are not personalised. Owning the Drifter’s Pass removes the interstitial advertisements.
On koidrift.com
The written pages of koidrift.com — this site around the game — may carry advertisements served by Google AdSense. Google, as a third-party vendor, uses cookies to serve ads based on your prior visits to this and other websites; you can opt out of personalised advertising at Google’s Ads Settings, and other vendors’ cookies at aboutads.info. The game itself, at koidrift.com, does not show advertisements inside the pond.
Website analytics
koidrift.com uses Cloudflare Web Analytics, which counts visits without cookies and without tracking you across sites.
Cookies
The game sets no cookies. It uses local storage, described above, for your progress and settings, and the service worker caches the game so it works offline.
Children
Koi Drift is suitable for everyone. It asks nobody, including children, for a name, email address, phone number, location or any login. The only identifiers involved are the random per-install identifier for gameplay statistics described above and, in the apps, the identifiers the advertising SDK uses, also described above. There are no chat features, no user-generated content and no way to contact other players inside the game.
Your choices
- Clear the site data in your browser, or uninstall the app on Android or iPhone, to delete everything the game stores on your device, including the random identifier.
- Reset or delete your advertising identifier in Android settings; on iPhone, Settings → Privacy & Security → Tracking and Apple Advertising control what any app may use.
- Write to us at the address below to ask what our server holds against a random identifier, or to have it deleted. You can find your identifier in the game’s log viewer (long-press the logo on the start screen).
Changes
If we change what the game collects, we will update this page and the date at the top before the change reaches you.
