Everything Byron holds about you can be deleted, permanently, whenever you want. If the app is still on your phone, do it yourself in ten seconds. If you've already removed it, ask us here.
Open Byron → Profile tab → scroll to the bottom → Delete account → confirm. Same on iPhone and Android.
It happens straight away: your account and everything attached to it goes from our servers, and the copy on your phone is wiped. You don't need to fill in anything below, and nothing waits in a queue.
Then we have to find your record for you, and that's harder than it sounds — Byron accounts are anonymous. There's no email address, password or name attached to one, so there is nothing to look you up by unless you tell us. Give us whatever you can remember below. Your display name is usually enough on its own.
All of it. There is no partial delete and nothing is held back:
Nothing is kept in a “deleted” state, there's no grace period, and it can't be undone. If you want your hoard back afterwards you start from scratch.
If you created a group that still has other members, the group carries on so their board keeps working — but your membership, your name and your scores are removed from it. A group left with nobody in it is deleted outright.
Deletion is the one built into the app, but it isn't the only right you have. To ask for a copy of your data, to correct it, or to object to how it's used, email byron@stupidhuman.dev — the same address, and the same identification problem, so bring the same details. The privacy policy sets out what we hold and why.
