Cue Master 3D: Privacy Policy
Last updated: 24 October 2026
Cue Master 3D ("the game") is made by Bui Dinh Dan ("we", "us"). This policy explains what information the game uses, why, and the choices you have. It covers the iOS and Android apps.
Summary
- No accounts and no sign-in. We never ask for your email, contacts, photos or precise location.
- Your progress is saved on your device.
- Online matches go through our game server, which receives only your in-game nickname, level, rating, avatar number, chosen cue and your shots, and keeps nothing after the match.
- The game shows optional rewarded ads (energy refill, an extra trickshot shot, double coins, free coins) and an occasional full-screen ad between matches through Google AdMob.
- The game has no in-app purchases and no analytics SDK of its own.
- We do not sell your information.
Data Collection & Analytics
Stored on your device
Your progress, settings, coins, gems, rating, cues, trickshot stars and statistics are stored only on your device. Deleting the game deletes them.
Online play
When you choose Play Online, the game connects to our game server (cuemaster3d.buidan.com) over an encrypted connection. The server receives your in-game nickname (generated by the game), level, rating, avatar number and equipped cue so it can find you an opponent at your level and show them your profile, plus your aim and shots during the match. This information is shared with your opponent for that match only. The server keeps it in memory while you are connected and does not store it, log it to a profile or link it to your device. Like any internet service, the server sees your IP address while you are connected; it is not stored. You can always play offline (vs AI, practice and trickshots) without connecting.
Advertising
The game shows optional rewarded ads (trickshot energy when you run out, one more shot in a trickshot stage, double coins after a match, free coins) and an occasional full-screen ad between matches through Google AdMob. To show and measure ads, Google may collect device and advertising identifiers, approximate location derived from your IP address, ad interactions and diagnostic data. Ads are never required to play.
Analytics
The game does not use Google Analytics, Firebase Analytics or any other analytics SDK.
Notifications
If you allow reminders, the game schedules local notifications on your device (your free Daily Spin is ready, your trickshot energy is full, a nudge after a few days away). They are created on the device; no push service or server is involved.
Third-Party SDK Disclosures
| Service | What it receives | Why | Policy |
|---|---|---|---|
| Google AdMob | Device and advertising identifiers (IDFA on iOS only if you allow tracking), IP address (used to estimate your region), device and app information, ad interactions and diagnostics. | To show and measure ads and prevent fraud. | Privacy policy |
| Our game server (cuemaster3d.buidan.com) | In-game nickname, level, rating, avatar number, equipped cue, your shots; IP address while connected. Nothing is stored. | Online matchmaking and matches. | This policy |

Your choices: in the EEA, UK and Switzerland the game asks for your consent through Google's consent form before any ad loads, and you can change it any time under Settings → Privacy Options. On iOS the game asks for permission before using your advertising identifier (App Tracking Transparency); you can change this in iOS Settings → Privacy & Security → Tracking. On Android you can reset or delete your advertising ID in your device settings. Online play is optional.
Children's Privacy (COPPA)
The game is not directed at children under 13, and we do not knowingly collect personal information from children under 13, in line with the U.S. Children's Online Privacy Protection Act (COPPA) and similar laws. Ads are configured as not child-directed and limited to content suitable for teens. There is no chat between players. If you are a parent or guardian and believe your child has provided personal information through the game, email [email protected] and we will delete it.
Account & Data Deletion
The game has no accounts, so there is no account to delete. To delete your data:
- On your device: uninstall the app. This removes everything the game stored.
- Online play: the game server does not store anything about you, so there is nothing to delete.
- Advertising data: data collected by Google AdMob is controlled by Google. You can reset your advertising ID in your device settings or manage it at https://myadcenter.google.com.
Security
Online play and ad traffic use encrypted connections (HTTPS/WSS over TLS).
Changes
If this policy changes, we will update this page and the date at the top.
