You control your WRECKCHORD account and can erase it and all of its data yourself at any time. No email to us required.
That's it - the account and its data are removed from our servers right away.
Any save kept locally on your own device stays on that device - we can't reach it. To remove that too, clear the WRECKCHORD app's data/storage on the device (or uninstall it). We may keep a minimal anti-abuse record where an account was banned for cheating, so bans can't be sidestepped by deleting and re-registering.
If you've lost access to your account, email support@wreckchord.com from the address on the account (or with your callsign) and we'll process the deletion for you.
