You can delete your account yourself, from inside the app, at any time. No request or waiting period is needed.
Deletion takes effect immediately.
Expenses and settlements you recorded in shared groups are kept but anonymized — they are detached from your identity and show only the display name snapshot, so the other members' balances stay correct. Groups you administered are handed to another member or archived.
If you can no longer sign in (for example, the app is uninstalled and your Google account is gone), email speeddevelop.dev@gmail.com from the address associated with your account and we will delete it for you.
