Invoice data and privacy
Invoice calculations, previews, field checks and downloads run locally in your browser. There is no invoice upload service, account system or payment processor in this version.
Where your draft lives
Without saving, the active draft lives in this browser tab. Save on this device explicitly writes one draft to localStorage in the current browser profile. Drafts can remain after closing the tab. There is no autosave and no automatic restoration. Use Delete saved draft to remove the stored copy.
Exports and imports
Downloads contain entered customer, seller and payment information. Imports read a selected JSON file locally and accept the application model only. Treat exported files as private business records. Local storage and downloads are not encrypted by this application.
Network requests
The application loads its pages and assets from the site host. It does not make invoice-data requests to third parties and includes no invoice-content analytics. The hosting provider may process ordinary request metadata such as IP address and page URL. Do not put invoice details into page URLs.
Shared devices
Other people using this browser profile may access a saved draft. Browser extensions or software on the device may also access page content. Use a trusted device and delete saved drafts when appropriate.
