The short version
- Made for children aged 3 and up – no personal information needed to play.
- No accounts, no ads, no chat, no tracking.
- Settings and purchased ducks stay on the device.
- Purchases and everything that leaves the app sit behind a parental gate.
- Parents can contact us at any time.
How we protect children
Crazy Rubber Duck is a rubber duck app for children aged 3 and up. We built it so that children can play without anyone collecting information about them.
What the app does not do
- No sign-up and no accounts; it never asks for names, photos, voice recordings or locations.
- No advertising, no chat and no messages to or from other people.
- No analytics, tracking or advertising software from other companies, and no identifiers used to follow a child across apps or websites.
- No access to the camera, microphone, location, contacts or photos.
What stays on the device
Settings, the duck counters and purchased content are stored only on the device. We never receive them. Deleting the app removes them.
Parental gate
Before a purchase, before restoring purchases and before anything leaves the app – email, store rating, these pages – the app asks a grown-up to solve a multiplication task.
Purchases
Purchases are handled by Apple, Google Amazon or Samsung. We never receive payment details.
If a child writes to us
If a child sends us an email, we only use the address to reply once and then delete the message.
The website
The website sets no cookies and does no tracking. It only remembers the chosen language inside the browser; we count visits anonymously on our own server. Details are in our privacy policy.
COPPA (United States)
The Children’s Online Privacy Protection Act (COPPA) protects the personal information of children under 13 in the United States. Crazy Rubber Duck does not collect personal information from children – no names, contact details, photos, voice recordings, location data or persistent identifiers for tracking. That is why no parental consent is needed to play.
If a child contacts us by email, we use the address only to respond once and then delete it, as COPPA permits. Parents can ask us at any time which information we hold about their child (normally none), have it deleted and stop any further use: quack (at) crazy-rubber-duck.com.
GDPR (European Union)
Under the General Data Protection Regulation, children’s personal data deserve special protection. The app processes no personal data of children: what it stores stays on the device. There is therefore nothing for which parents would have to give consent under Art. 8 GDPR. You can find everything about the website and the app in our privacy policy.
