Coil Arena — Privacy Policy
In short: Coil Arena has no accounts, no ads, no purchases and no analytics. To play online your device talks to our game server; nothing about you is written to a database, and your progress stays on your device.
Who we are
Coil Arena is made by Big Bad Agency, 1616 1 Street NE, Calgary, AB T2E 4A1, Canada. Contact: hello@bigbad.agency.
What the game sends to our server
To play, your device connects to our game server (coil.bigbad.agency on the web and Android; coil.teambooks.app in the iPhone app). It sends:
- the display name you type (optional — leave it empty and you play as "You"),
- your controls (which way you steer, whether you boost), your screen size (so the server knows what you can see), party-room and rematch requests, ping timestamps, and the colour you picked and its skin level,
- your character look with each run: which character you play and the hat, eyes, pattern, trail, name flair, title and victory pose you wear, sent as 8 small numbers. It is cosmetic only: it changes how your snake looks to other players, never how it plays,
- a random play ID made on your device (a random number, not your phone's hardware ID). The server uses it only to give the once-a-day "Golden Start",
- if you report a player's name: that name and the reason you picked.
Other players in your room see your display name, your snake in its colour and character look, and your length. There is no chat.
What we keep
Nothing after your game. The server holds your name and run in memory only while your snake or room exists. It holds your random play ID in memory only for the current day (UTC) so the Golden Start is given once, then forgets it. None of this is written to a database or to logs. There are no accounts.
The one exception is a report. When a player reports a display name, the server writes that name (as the room showed it), the room code, the game mode, the reason and the time to a report file, so we can read it and block offensive names. Nothing about the person who reported is written: no name, no device ID, no IP address.
Your IP address
Like any internet connection, our server sees your IP address in order to deliver the game; in the iPhone app, Cloudflare carries the connection and sees it too. We don't store it.
On your device
The game saves on your device: your chosen name, colour, look and sound setting; your stars, missions, unlocked skins, skin levels, titles, lifetime stats and the days you played; any names you chose to hide; and the random play ID. Uninstalling the app or clearing its data (or your browser's site data) removes all of it, and we cannot recover it.
What we don't do
No advertising, no advertising ID, no analytics or tracking, no location, no contacts, no sale or sharing of data with anyone.
Children
Coil Arena is not directed at children under 13. Display names are typed by players. The server refuses names on a block list, and any name can be hidden on your device or reported from the game.
Deletion
We store nothing about you to delete, except a display name someone reported (see "What we keep"); email us to have one removed. Your progress lives on your device; remove it by uninstalling or clearing the app's data. Questions: hello@bigbad.agency.
Changes
If the game ever adds ads, purchases, accounts or analytics, this page will be updated before that version is released, with a new effective date.
