Privacy Policy
Second Player Studios · Last updated: 27 October 2026
The short version: Patient Zero has no accounts, no ads, no analytics and no purchases inside the game. Playing alone, and designing levels, sends nothing anywhere. Playing with friends online uses Unity's multiplayer services, which receive an anonymous player ID and your IP address so they can connect you. Playing on the same Wi-Fi tells other devices on that network your device's name so they can find your game.
What the game stores on your device
- your settings (volume, vibration on or off, camera style)
- which levels you have unlocked, your stars for each level, and the last level you played
- the levels you make in the level designer, saved as small text files in the game's own folder on your device (
Android/data/com.secondplayerstudios.patientzero/files/LevelDesigns), where you can copy them over USB if you want to
This lives on your device. It never leaves it, and uninstalling the game deletes it.
Sharing levels you make
When you tap Share on a level, the game puts a text code for that level on your device's clipboard. What happens next is up to you: you can paste it into any messaging app, and a friend can paste it back into their game. The game itself uploads nothing, and we do not host, see or store any level.
Playing online (Control Group, Online)
Online games run through Unity Gaming Services, operated by Unity Technologies, so that phones on different networks can reach each other without any network setup:
- Unity Authentication signs the game in anonymously when you host or join online. It creates a random player ID, not linked to your name, email or any account, so the service can recognise the session. We never ask for or receive any login.
- Unity Relay carries the game's traffic between players. To do that it necessarily receives each player's IP address (from which a rough, city-level location can be inferred) and the game data of the session itself: positions, bites, the state of the level. Online, players appear to each other as "Player 1", "Player 2" and so on; your device's name is not sent.
Unity processes this data to provide the service, under its own privacy policy. We do not receive your IP address and we do not combine any of this with anything else. If you never play online, none of it happens.
Playing on the same Wi-Fi (Control Group, Local)
A Wi-Fi game is announced to other devices on the same local network with your device's name (for example "Pixel 8") and the name of the level being played, so friends' menus can list it. The other players in a game also see each device's name in the lobby. Joining sends game data directly between the devices on that network. Nothing goes over the internet.
If your device's name includes your own name, you can change it in your phone's settings (About phone, Device name) before playing with others.
What we do not do
- We do not collect names, email addresses, phone numbers, contacts or photos.
- We do not use advertising, advertising IDs, or analytics. Unity's engine diagnostics are turned off.
- There are no in-game purchases.
- We do not sell or share data with anyone.
Children
Patient Zero is not directed at children under 13. Online play has no chat and no way to send messages; players are only connected by sharing a six-character code with friends.
Your choices and deleting data
- Play alone, design levels, or play on Wi-Fi only, and no data reaches any service.
- The anonymous player ID belongs to this installation; uninstalling the game removes it from your device. To ask for the data Unity holds for that ID to be deleted, contact us at the address below and we will pass the request to Unity.
- Your levels and progress are only on your device: delete a level from the Custom Levels list, or uninstall the game to delete everything.
Purchases
Patient Zero is bought through the store (Google Play), under that store's own terms and privacy policy. We receive no payment details.
Changes
If a version of the game changes what it sends anywhere, this policy is updated before that version is released, with the date the change takes effect.
