What will be deleted
• Your personal data (email, name, avatar, phone). • Your credentials (password, Google/Apple links, passkeys). • Your personal expenses, custom categories and payment methods. • Your friendships and settings. Groups shared with other people are kept; your participation will be anonymized as "Deleted user".
