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 pilot.
- The microphone never sends any sound to our server: everything happens on your phone.
- Google ads (adjustable in Options), and one-time purchases to remove them or get a skin.

In short
Coin Coin Squadron 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 (golden feathers, records, upgrades, cosmetics, medals, settings, recorded quacks, best flight) 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.
Online play (Ranked, Duck Flock, Co-op with friends, 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 pilot name (two words picked from lists, never free text), your plane's look, your results (Ranked scores, medals and season points, Duck Flock rating and wins) and the paths of your ranked flights, used as ghosts for other pilots. We never ask for a real identity. Your pilot name, look and results are visible to other players. A transfer code holds a copy of your progress and is deleted once used or after 24 hours.
Live games
During a co-op game or a duel, your plane's position and state are relayed to the other pilots 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 hash of the IP address, deleted after one hour. 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, legendary skins and items sold individually are paid through the App Store or Google Play. We never receive any payment information.
Retention
Ranked races and their ghosts: current and previous season. Transfer codes: 24 hours at most. Anti-abuse counters: one hour. Pilot name, medals, season points and Duck Flock rating: 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 pilot name: we will delete the ID and everything linked to it.
