What the service is
An API that turns HTML or a stored template into a PDF, and a free invoice generator built on the same renderer. There is no dashboard, no self-service signup and no payment. Keys are issued by hand, and the plans page describes limits the API enforces rather than a purchase you can make.
The invoice generator
Free, with no account and no watermark, and it stays that way. The invoices you make with it are yours, for any purpose, with nothing to attribute. Downloads are limited to ten an hour from one connection so that one caller cannot spend the shared budget the tool runs on.
Your documents
What you send stays yours. We render it and delete it on the schedule in the privacy page: an hour for the invoice generator, the plan retention for an API key. We claim no licence over it beyond what rendering it requires, and we do not use it for anything else.
What you should not send
Every render opens your HTML in a real browser, so the renderer is built to assume the document is hostile: outbound requests are validated at connect time, private address ranges are refused, and a set of attacks is attempted against it in CI on every change. Do not send documents designed to test that. If you want to probe it, write to us and we will talk about it, which is a much faster route to an answer than a rate-limited guess.
Do not use the service to produce documents that impersonate somebody, or content that is illegal where you are. An account doing either loses its key.
Your key is yours to protect
A live key spends your credits, and anything shipped to a browser is readable. Keep keys on your own servers. If one leaks, write to us and it is revoked immediately, with no grace window. Rate limits count per account rather than per key, so issuing more keys does not raise them.
What we do not promise
There is no uptime commitment during early access, and no support obligation beyond a person reading hello@paperpony.dev. Free-plan output is watermarked and free-plan renders run with JavaScript disabled. Credits are a hard stop rather than an overage bill: when they run out, renders stop.
The retention numbers are enforced by a sweep rather than promised by a table, which also means output is genuinely gone when it expires. Keep your own copy of anything you need to keep.
Changes and ending
You can stop using the service at any time, and asking for your data to be deleted is one email. We can withdraw a key, and if we do it without cause we will say why.
What these terms do not cover yet
There is no governing-law clause here, no limitation of liability, no warranty disclaimer and no notice period for changing this page. That is deliberate rather than an oversight. Those four are written by a lawyer, and a clause invented to fill a gap is worse than the gap: it reads as binding and is not.
They arrive before paid access opens. Until then there is no payment, no contract to buy, and nothing either side is exposed to that the four would govern. If you need them settled sooner, say so at hello@paperpony.dev and they will be.
