Privacy Policy Ninja Dash. Last updated: September 19, 2026. Ninja Dash ("the app") is developed and published by Yinghua ("we", "us").
DATA WE STORE ONLINE. The app stores exactly three things on our leaderboard service (Google Firebase): the display name you choose, your best score, and a random 6-character player ID generated on your device. No email address, no real name, no location, no device identifiers, and no other personal data are sent to us. (The advertising ID used by Google AdMob is described under ADVERTISING below; it goes to Google, not to us.)
WHO CAN SEE IT. Your display name, player ID and best score are shown on the public WORLD leaderboard inside the app, and to any player who adds your player ID as a friend. Please do not use your real name as your display name.
DATA STORED ONLY ON YOUR DEVICE. Your settings, character design, coins, unlocked auras and capes, and friend list are saved only on your own device and are deleted when you uninstall the app.
PHOTO FOR SKIN COLOUR. The character creator can pick your ninja's skin colour from a photo you choose. The photo is read once, on your device, to work out a single colour; only that colour is kept. The photo itself is not saved by the app and is never uploaded anywhere.
IN-APP PURCHASES. The app sells packs of in-game coins. All purchases are processed by Google Play Billing. Payment is handled entirely by Google: we never see, receive or store your card number, billing address, Google account or any other payment information, and no purchase data is sent to our servers. What we receive from Google is only a confirmation that a purchase completed, which the app uses to add the coins to your balance. Your coin balance and what you have unlocked are saved only on your own device, alongside the rest of your settings.
COINS CAN BE SPENT ON RANDOMISED ITEMS. Coins, whether earned by playing, received for watching an ad, or bought with money, can be spent on the Lucky Draw, which awards a cosmetic aura or cape at random. The star drop rates are published inside the app on the Lucky Draw screen ("Drop Rates"). These items are cosmetic only: they cannot be sold, traded, transferred, or exchanged for money or anything of real-world value, and there is no cash-out of any kind. Coins are consumable and have no monetary value. Refunds are handled by Google Play under Google's refund policy, not by us.
ADVERTISING. The app shows optional rewarded video ads, served by Google AdMob. An ad only plays when you choose to watch one (for example, to double the coins from a run or to get free coins in the shop); the game never shows ads on its own, and you can play fully without ever watching one. To serve and measure ads, Google's advertising SDK collects your device's advertising ID, approximate location based on your IP address, and ad-interaction data, and processes them under Google's Privacy Policy (policies.google.com/privacy). We never receive this data ourselves. In the EEA, UK and Switzerland you are asked for consent before personalised ads are shown. You can reset or delete your advertising ID at any time in your Android settings (Settings > Google > Ads). The app contains no analytics and no other tracking.
OFFENSIVE NAMES AND REPORTING. Display names are automatically checked against a filter that blocks slurs and profanity. Players can report any name on the leaderboard using the report button next to it; reported players are hidden immediately for the person who reported them, and we remove offending records from our database.
DATA DELETION. To remove your display name, player ID and score from the leaderboard, email us at the address below with your player ID (shown on the app's home screen) and we will delete the record. Everything else the app stores lives only on your device and is removed when you uninstall the app. Advertising data is held by Google; you can reset your advertising ID in Android settings.
CHILDREN. The app is intended for players aged 13 and over. It collects no personal information itself. Because the app sells coins that can be spent on randomised cosmetic items, some rating authorities apply a higher age band in their territory; see the age rating shown on the app's Google Play listing for your country.
CHANGES. If a future version changes any of the above, this policy will be updated at this same address before the update is released.
