Privacy Policy
The short version
Marble Derby does not sell your personal information and does not track you across other companies' apps and websites. Ads only appear when you choose to watch one for a reward. The game works without an account. If you choose to sign in or buy coins, the limited information described below is used.
What stays on your device
Your marble, level, coins, achievements and settings are saved on your device so the game remembers your progress. If you delete the app without signing in, that progress is removed.
Accounts (optional)
You can sign in with Apple to back up your game and restore it on another device. If you do, we store your Apple user identifier (an ID Apple gives us, not your email, unless you choose to share it) and a copy of your game progress on our server. If you buy coins without signing in, we create an anonymous account ID for the purchase. You can delete your account and its backup at any time inside the game (Shop, Delete account). Deleting removes your backup and the link to your Apple ID; we keep an anonymous record of purchases for accounting and refund purposes.
Purchases
Coin packs and other purchases are processed by Apple. We use RevenueCat, a purchase-management service, to confirm purchases. RevenueCat receives your anonymous account ID and purchase details, and does not receive your payment information. Apple handles all payment details; we never see your card.
Optional reward videos (ads)
Some features let you choose to watch a short video ad for a reward, such as free power-ups. You never have to watch one, and there are no ads between races. These ads are provided by Google AdMob. We set them up for a family audience: they are marked as directed to children, limited to content suitable for all ages, and are not personalized. To show and measure an ad, Google may collect limited information such as an app-specific device identifier, approximate location based on your IP address, and whether the ad was watched. We do not use ads to track you across other apps and websites. You can read Google's policy at policies.google.com/privacy.
What we collect, in short
Only if you use these features: your Apple user identifier, your game progress backup, and purchase history. The game shows ads only when you choose to watch one (see above). We do not collect your name, location, contacts or photos, and we do not use analytics tools.
Children
The game is designed to be suitable for all ages. We do not knowingly collect personal information from children. Reward video ads are set up as directed to children, are limited to content suitable for all ages, and are not personalized.
Your choices
You can play without signing in, delete your account inside the game, or contact us at pkanddad.games@gmail.com to ask what we hold about you or to have it deleted.
Changes
If we change how we handle information we will update this page and its date.
