Privacy Policy
This policy covers the app Pixelo: Pixel Art Coloring (vn.fighttech.pixelo) and no other app. It is
published by Trung-Hieu Tran, the developer named on the Google Play store listing for this app, who can
be reached at trunghieu4121993@gmail.com. The app works without an account and is
built to collect as little as it can. This page says what is collected, why, and what you can do
about it.
1. Data we do not collect
We do not ask for your name, e-mail address, contacts, precise location, photos or any account. There is no sign-up. Your colouring progress is stored only on your device.
2. Data collected automatically
| Data | Purpose | Processor |
|---|---|---|
| Anonymous usage events (screens opened, picture started or finished, hint used, purchase started) with a random install identifier and the device's Advertising ID | Understand which features are used and improve the app (analytics) | Google Firebase Analytics |
| Crash reports: stack trace, device model, OS version, app version, free memory, the screen you were on | Find and fix crashes | Google Firebase Crashlytics |
| Purchase tokens and product IDs | Deliver and restore Premium | Google Play Billing |
| When an ad is shown: Advertising ID, IP address and the approximate (country / city) location derived from it, device model, OS version, language, screen size, app version, and whether the ad was viewed or clicked | Show the ad, credit a rewarded hint, prevent fraud and measure ad performance | Unity Ads (Unity Technologies) |
| Nearby-device names and the colouring state you share while a “Play together” room is open | Let two devices on the same Wi-Fi colour one picture together | Nobody — it stays on your local network and is not sent to us or to a server |
The install identifier is a random UUID created by the app. It is not linked to a Google account or to any personal information, and it is gone when you uninstall the app. Analytics data is retained by Firebase for up to 14 months.
3. Ads
Pixelo is free and shows ads: a banner on some screens, an occasional full-screen ad between pictures, and a rewarded video you can choose to watch in exchange for a hint. Premium removes the banner and the full-screen ads. Ads are delivered by Unity Ads, which processes the data in the row above under its own privacy policy. You can opt out of personalised advertising there, or by resetting or deleting your Advertising ID in Android Settings › Privacy › Ads.
4. Play together (local network)
When you host or join a room, the app advertises itself on your Wi-Fi network so the other device can find it, and the two devices exchange the picture you are colouring and the taps you make. The name shown to the other player is the one you type in the app; it is stored on your device only. Nothing from a room reaches our servers, because there are none.
5. Permissions
- Vibrate — a haptic tick when an area fills. Can be switched off in More.
- Storage (Android 9 and lower only) — to save a finished picture to your gallery when you tap Save.
- Internet, network state, nearby Wi-Fi devices — purchases, ads, anonymous statistics, and finding a nearby player when you open a Play-together room. Colouring itself works fully offline.
6. Purchases
Premium subscriptions and the lifetime purchase are processed by Google Play. We never see your payment details. Google's handling of that data is described in the Google Privacy Policy.
7. Children
The app is suitable for all ages and is not directed specifically at children under 13. We do not knowingly collect personal information from children.
8. Your choices and how to delete your data
- Uninstalling the app deletes all local progress and the install identifier.
- To request deletion of the analytics data tied to your install, e-mail trunghieu4121993@gmail.com from any address with your device model and the approximate install date. We delete it within 30 days.
- Reset or delete your Advertising ID in Android Settings › Privacy › Ads to break the link between ad requests and this device.
9. Changes
We will update this page when our practices change and note the effective date above.
