Privacy.

Mono Invoice. is designed so that privacy isn't a policy — it's an architecture. The short version: your invoice data never leaves your device.

What happens to your invoice data

Everything you type — your business details, client names, line items, amounts, logos — is processed entirely in your browser. Nothing is sent to a server. There is no database, no account, and nothing for us to store, sell, or leak.

Auto-save

Your current invoice is saved in your browser's local storage so it's still there if you close the tab. That data lives only on your device. Clearing your browser data removes it completely.

PDF generation

PDFs are generated by your own browser's print function, on your device. The finished invoice is never transmitted anywhere.

Third parties

The page loads the Inter typeface from Google Fonts, which means your browser makes a standard font request to Google's servers. No invoice content is included in that request.

Questions

This page describes the entire data practice of Mono Invoice. — there is intentionally nothing more to disclose. If something is unclear, the product's design principle is the answer: if it would require sending your data somewhere, Mono Invoice. doesn't do it.
