Privacy Policy — Invoice Maker

Last updated: 2026-07-07

What the extension does

Invoice Maker is a browser extension that reads the email you currently have open (Gmail, Outlook Web, or another webmail page) and uses pattern matching to pre-fill an invoice form with best-effort guesses — sender/company name, date, amounts, and reference numbers. You always review and correct this data yourself before anything is generated. The extension then renders a PDF invoice using your own saved branding (logo, colors, business details) and can export the same data as CSV or JSON.

What data we collect

None. We — the developer — do not collect, receive, transmit, or have access to any of your data. There is no backend server, no analytics, and no third-party API involved in any part of the extension's operation.

What data the extension reads, and where it goes

• Email content — read directly from the page's DOM (or your text selection) only when you click the extension on an open email. It is parsed locally using regular expressions and never leaves your browser, is never uploaded, and is never sent to any server, including ours.
• Business/branding details, templates, invoice history, and logo images — stored locally using the browser's built-in chrome.storage.local and IndexedDB APIs. This data stays on your device and syncs only if your own Chrome profile sync is enabled by you — the extension does not add any sync or transmission of its own.
• Generated PDFs / CSV / JSON exports — created entirely client-side and saved to your Downloads folder using the browser's download API. Nothing is uploaded.

Permissions we request, and why

• activeTab — lets the extension read the page you're currently viewing only when you actively click the extension icon; it has no access to other tabs or background browsing.
• scripting — used to run the on-demand text-extraction script on the current tab for webmail providers without a dedicated content script.
• storage — used to save your branding templates, settings, and invoice history locally via chrome.storage.local.
• downloads — used to save the generated PDF/CSV/JSON files to your device.
• Host access to mail.google.com and outlook.office.com / outlook.live.com — used solely to run the Gmail/Outlook-specific extraction content scripts when you have those sites open.

Data sharing

We do not sell, rent, trade, or share any data with third parties, advertisers, or analytics providers, because no data ever reaches us in the first place.

Data retention and deletion

All data is retained locally until you delete it yourself (e.g. removing a template, clearing invoice history, or uninstalling the extension, which removes its local storage entirely).
