Developer builds invoicing app with no accounts, no server, and no user data stored

A developer launched PDF Pebble, a free invoice-generator app aimed at sole traders, deliberately built without user accounts, a backend server, or any server-side data storage. All invoices, business details, and documents are stored locally on the user's device, a choice made to avoid responsibility for holding sensitive financial data for thousands of small businesses. The app supports multiple tax regions — including Australia, India, the UAE, Europe, and the US — by modelling each region as a data record rather than using branching code logic. It also features two independent renderers to handle both standard A4 invoices and narrow thermal receipt formats, which require fundamentally different layouts. The trade-offs are acknowledged openly: there is no cross-device sync, no data backup, and no way to track or re-engage users since no account information is ever collected.
