The duck contract
The summary in three quacks. The full text is right below.
- No account, no email, no real name: you stay an anonymous duck.
- The microphone never sends any sound to our server: everything happens on your phone.
- Google ads (adjustable in Options), and a one-time purchase to remove them.
Signed: the duck

In short
Coin Coin Splash is played without an account. We never ask for your name, email or phone number, and we do not sell any data.
On your phone
Your progress (coins, best depth, cosmetics, settings, recorded quacks, best run) is stored on your device. The microphone (optional) is analysed on the phone to detect a breath, and Quack Studio records your quacks on the phone: no sound is sent to our server. If you choose “Export a file”, that file contains your quacks, and you decide who to share it with.
Online play (Royal Net, Reverse Fishing, With friends, Daily Bath, transfer codes)
The first time you play online, the game creates a random ID. Our server (Cloudflare) stores: that ID and the hash of a secret key, your duck name (two words picked from lists, never free text), the cosmetics you wear, your results (places, depths, medals, points, Daily Bath and Reverse Fishing scores), and the last time you opened a waiting page, to count the ducks present. We never ask for a real identity. Your duck name, outfit and results are visible to other players. A transfer code holds a copy of your progress and best run, without your recorded quacks, and is deleted once used or after 24 hours.
Live games
During a live game, your duck's position and state are relayed to the other players in the room, without being stored. On the same Wi-Fi, this stays between your phones. There is no chat between players.
IP address
To prevent abuse, the server counts requests using a salted, truncated hash of the IP address, deleted after a few hours. The address itself is never stored.
Ads
The game shows ads from Google AdMob. Google may use device identifiers to show and measure ads, according to your choice at first launch (GDPR consent in Europe, Apple's tracking permission). You can change your mind in Options > Ad privacy, or in your phone's settings. Google's policy: https://policies.google.com/privacy
Purchases
The “No Ads” pack and items sold individually are paid through the App Store or Google Play. We never receive any payment information.
Retention
Race history: 60 days. Daily Bath scores and waiting page presence: 30 days. Reverse Fishing games: 7 days. Transfer codes: 24 hours at most. Old race runs: current and previous season. Duck name, medals and season points: until you ask us to delete them.
Children
The game asks for no personal data. Ads for younger players follow Google's appropriate settings.
Your rights
You can ask for access to your online data or for its deletion by writing to us with your duck name (Royal Net page): we will delete the ID and everything linked to it.
