What we process
When you use the plugin, ChatGPT sends the details needed to build the invoice: your business and your customer's names and contact details, invoice number, dates, line items, rates, discount, tax rate, shipping, notes, and payment instructions. We use them to return the invoice and then discard them. We do not store them, build profiles, or sell data.
The PDF and CSV download links carry the same invoice details inside the link itself, compressed, so the file can be rebuilt on request. The server does not save the file. Anyone you share a download link with can open that invoice, so share the PDF itself rather than the link.
Logs
Our host (Vercel) keeps standard request logs, such as time, URL path, and IP address, for a short period for security and reliability. We do not log invoice details on purpose, but a download link is a URL, so it can appear in those logs.
Anonymous usage counts
To see which features people use, we record anonymous usage counts: which tool ran, whether it succeeded, how long it took, and a few non-personal aggregates such as the number of line items and the currency code. Page views and downloads are counted the same way, with a coarse flag for automated traffic. These counts never include invoice contents, amounts, customer or business details, names, IP addresses, or browser details.
If you join the list on our homepage, we store your email address, the page you used, and the time in our database (Neon, hosted in the US) to send product updates about new tools. You can ask us to delete it at any time by emailing gabriel@primecapequity.com. To stop spam, the form keeps a one-way hash of the sending network address for one day to limit repeated sign-ups; the address itself is not stored. If you email us for help, we keep that email to reply.
