Build Island Privacy Policy
Summary
Build Island is a brick-building game you can play alone, or online with other people on the same island. Playing alone sends nothing anywhere. When you choose to play online, the game uses Epic Online Services (a free service from Epic Games) to find other players and connect your headset to their headsets. We do not sell data, show ads or run analytics, and we have no account system of our own.
1. Information we collect
We do not ask for your name, email address, contacts, location, photos or payment details. Nothing leaves your headset until you press an online option on the game's Play Online panel (Quick Join, Private Island or Join With Code). Then:
- An anonymous player identifier. Epic Online Services gives your headset an anonymous ID (an Epic "product user ID") created from an anonymous device identifier. If your Meta account can confirm you own the app, the game may use a Meta user proof to sign you in to Epic instead; in that case your Meta user ID is shared with Epic for sign-in only.
- Island information. The island you host or join is listed in an Epic lobby with the game's name, version, whether it is private and, for private islands, a 4-digit code.
- Live game data. While you are on a shared island, your headset sends the other players' headsets your head and hand positions, your chosen avatar, the brick you are holding and where it is about to go, and every brick you place, move, recolour or remove (which brick, which colour, which studs). This is needed to show you, and your building, on their island. When you join, the host sends you the bricks already on the island.
- Voice (optional, off by default). Only if you turn VOICE on, your microphone audio is sent live through Epic's voice service to the other players on your island. We never record or store it. You can mute any player or everyone.
- Reports. If you report a player, the report (their anonymous ID, a reason and your anonymous ID) is sent to Epic's player reporting service so we can review it.
2. Information stored on your device
The app saves on your headset: your world of bricks, your chosen avatar, music track and volume, and the list of players you have blocked. This data never leaves the device and is deleted when you uninstall the app.
3. How information is used
Only to run shared islands (finding an island, connecting players, keeping the bricks in sync), to carry optional voice chat, and to act on reports (for example, preventing a banned player from playing online). It is not used for advertising or profiling.
4. Sharing
Online play is provided through Epic Online Services, which processes the data above under the Epic Games privacy policy (epicgames.com/site/privacypolicy). The other players on your island receive your live game data and, if you turn it on, your voice. Meta handles platform features such as purchases and its system reporting under Meta's own privacy policy. We do not share data with anyone else.
5. Retention
We retain as little as possible. Lobby and island data exist only while an island is open. Voice is never stored. Your anonymous Epic ID remains with Epic so the same headset keeps the same ID; reports are kept only as long as needed to review them and enforce the rules. Data on your headset is kept until you uninstall the app.
6. Children
The game is rated for "Users Interact" content. Online play can be avoided entirely by building alone. Voice chat is off unless turned on, any player can be muted or blocked from the in-game Builders list, and private islands can be limited to friends who have the code. We do not knowingly collect personal information from children.
7. Permissions
The app uses the internet permission for online play, and the microphone (record audio) permission only if you turn voice chat on - you are asked first. It does not use the camera, location, contacts or eye tracking.
8. Your choices
Build alone to share nothing. Online, you can leave an island at any time, keep voice off, mute, block or report any player. To ask about or request deletion of data connected to your anonymous ID, contact us at the address below.
9. Changes
If this policy changes, the updated version will be published at this address with a new effective date.
