Swarm Vector: Privacy Policy
Last updated: 16 October 2026
Swarm Vector ("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 and the browser version at https://swarmvector.buidan.com.
Summary
- No accounts and no sign-in. We never ask for your name, email, contacts, photos or precise location.
- Your progress is saved on your device.
- The mobile apps show optional rewarded ads and an occasional full-screen ad through Google AdMob. The browser version shows no ads.
- The game contains no analytics SDK of its own.
- Online play sends gameplay data to our game server only while you play online.
- We do not sell your information.
Data Collection & Analytics
Stored on your device
Your progress, settings, callsign and unlocks are stored only on your device (in the browser version, in your browser's local storage). They are never sent to us. Deleting the game, or clearing site data in your browser, deletes them.
Online play
When you choose online play, the game connects over an encrypted connection (TLS) to our game server (wss://play.swarmzone.click). The server receives:
- Your callsign and pilot portrait number, shown to other players in the room.
- Your controls and in-game state (steering, boost, formation), used only to run the match and discarded when you leave.
- Your best online run (callsign, score, peak swarm size, trails sliced, sector reached, date), stored on the public global leaderboard.
- Your IP address, which is part of any internet connection. It may appear briefly in server logs for security and troubleshooting.
There is no chat. Offline matches against computer players send nothing to our server.
Advertising
The mobile apps show optional rewarded ads and an occasional full-screen ad 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.
Browser version
The browser version is served from swarmvector.buidan.com. It shows no ads and loads no analytics or advertising scripts. Our web host may keep standard access logs (IP address, browser type, pages requested) for security and to keep the site running.
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 |
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 in the game's 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.
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. 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 (or, in the browser, clear site data for swarmvector.buidan.com). This removes everything the game stored.
- Global leaderboard: email [email protected] with your callsign and we will remove your entry within 30 days.
- 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
Information sent by the game travels over encrypted connections (HTTPS/TLS).
Changes
If this policy changes, we will update this page and the date at the top.
