Knock Knock Courier – Privacy Policy
Effective date: 29 October 2026
Knock Knock Courier needs no account and keeps your game progress only on your device; the only part that sends data off the device is Google AdMob advertising. This policy covers the Knock Knock Courier mobile game for Android ("the Game"), developed and published by independent developer Volkan Yalçın ("we").
Data we handle
Data | Where it is kept | Who can access it |
|---|---|---|
Game progress: money, level, XP, deliveries, vehicles bought, buildings, hired couriers | On your device only | Only you |
The company name you type in the game | On your device only | Only you |
Settings: sound, language, graphics quality, steering mode | On your device only | Only you |
Advertising ID, IP address, device model, OS version, language, approximate location (from IP), ad interactions | Google's servers | Google (AdMob) |
Your ad consent choices | Your device and Google's servers |
The Game does not ask for location, camera, microphone, contacts or file permissions. We have no servers, accounts or analytics of our own. Please don't type your real name or other personal details as your company name.
How data is used
- Game data: to save your progress and show your company name on the depot billboard. Legal basis: performing our contract with you.
- Advertising data: to show interstitial ads and the rewarded ads you choose to watch, cap ad frequency, prevent fraud, and personalise ads if you consent. Legal basis: your consent for personalised ads; our legitimate interest for non-personalised ads.
We do not sell your data or share it with anyone other than our ad partner.
Third-party services
- Google AdMob: interstitial and rewarded ads — Google Privacy Policy, How Google uses data from partner apps.
- Google User Messaging Platform (UMP): asks for ad consent in the EEA, UK and Switzerland — Google Privacy Policy.
- Unity engine: runs the Game; Unity Analytics and crash reporting are turned off — Unity Privacy Policy.
Consent and ad choices
In the EEA, UK and Switzerland the Game shows Google's consent form before any ads; if you decline, you only see non-personalised ads. Anywhere, you can reset or delete your advertising ID (Android Settings → Privacy → Ads) or turn off personalised ads at Google Ad Settings. Clearing the Game's data brings the consent form back. Watching rewarded ads is always optional.
Retention, deletion and security
Game data stays on your device until you uninstall the Game or clear its data (Android Settings → Apps → Knock Knock Courier → Storage → Clear data); we hold no copy. Advertising data follows Google's retention policy. Traffic to Google uses encrypted HTTPS connections.
Children
The Game is not directed at children under 13 and does not knowingly collect personal data from them. If you believe a child under 13 has used the Game and ad data was shared, contact us and we will act on it.
Your rights and contact
Under the GDPR and Turkey's KVKK (Law No. 6698) you may access, correct and delete your data, object to processing, and withdraw consent. You can exercise these for game data directly with the deletion steps above, and for ad data through Google My Account.
