Your account
Username, email, password, and deleting everything.
Changing details
Username, display name, email, and password all change from Profile → Settings in the app.
Deleting your account
Settings → Delete account. You'll type your username to confirm. This removes your profile, every Splat and its files, likes, views, and reports — permanently. There is no undo and no grace period.
Blocked accounts
Blocking is bidirectional: you never see their Splats, they never see yours. Manage blocks from the feed overflow menu.
