If you still have the app, the fastest way is in-app: Settings → delete this household or delete my account — both permanently erase your data 30 days later (cancellable from the same screen until then), and either way you can export your data first. See our Privacy Policy for exactly what each one erases.

Don't have the app installed, or would rather not? Use the form below instead. This isn't instant — we verify it's really you before erasing anything, same as any other request to delete a real household's financial data — but we'll follow up at the email you give us.

We'll reply from support@duolign.co.uk once it's handled.
