Privacy
Gardiner Invoices keeps the working book on this device until you sign in. After a login, the book is stored against that account so the same desk opens again. Card numbers typed at checkout are checked and then discarded. They are not written to the book.
Speech you dictate stays in the browser. It is not sent to a speech service by this desk. Email and WhatsApp open those apps with the words you wrote. We do not read the customer list for advertising.
You can remove customers, invoices, and the login’s book by deleting the rows on the desk. Account deletion follows from signing out and asking the operator of this desk to drop the login.
