What to write about

• Something is broken. A field that will not accept a value, a PDF that will not download, a layout that renders wrong. Tell us the browser and version, the device, and what you were doing when it happened. That is usually enough to reproduce it.
• A character printed as a question mark. The PDF uses the standard PDF fonts, so scripts outside Latin and Western European ranges cannot be drawn. Tell us which language you need and it helps us prioritise embedding a font that covers it.
• Privacy questions. Anything in the privacy policy that is unclear, including what advertising partners do and do not receive. If you want a draft wiped from a shared computer, that is something you clear in the browser yourself; we never held a copy.
• Advertising and policy. If an ad on this site looks broken, misleading, or out of place, we want to know which page and roughly when you saw it.
• Corrections to a guide. If something in the guides is wrong, out of date, or misleading for your country, point at the paragraph. We would rather fix it than leave it up.
• Feature requests. Useful, with one caveat: the answer is often no, because the tool stays deliberately narrow. Requests that fit the shape of a browser-only document generator get taken seriously.

What to include so we can help

A short note is fine. For bugs, the useful extras are: browser name and version, phone or desktop, whether you were on the invoice or the estimate page, and a one-line description of what you expected versus what happened. Screenshots help when a layout is wrong. Do not paste full bank details or a client’s private address into the email unless the bug cannot be shown without them.

Subject lines that help us sort mail: “Bug: PDF download on Firefox”, “Guide correction: payment terms”, or “Ad issue on /guides/...”. A clear subject beats a long preamble.

What to expect back

You should get a human reply, not an auto-ticket. That usually means a few days, not a few hours. If the question is a clear bug, we fix it when we can and tell you when it is live. If the question is a feature that would need a server or a paywall, we will say no and explain why rather than promise a roadmap we cannot keep.

We do not offer phone support, live chat, or same-day emergency help with a client invoice. The tool is free and ad-supported; support matches that.

Privacy of your email

Mail you send to tinyutilitylab@proton.me is read by Tiny Utility Lab to answer you. We do not sell that mail, put it on a marketing list, or turn it into a lead for a paid product. We may keep the thread while the issue is open, then delete it when it is done, unless we need a short record of a bug we fixed. Your invoice contents never travel with a normal support email unless you paste them in yourself.

The site itself still does not collect invoice data. Email is the only channel where you might voluntarily send us something from a document, and even then it is optional. See the privacy policy for what the product stores locally and what advertising partners see.

What we cannot help with

Not evasion, just the consequence of how the tool is built. There is no server holding your documents, so:

• We cannot recover a lost draft, a deleted invoice, or a PDF you did not save. We never had a copy. Drafts live in your own browser’s local storage and clearing site data removes them permanently.
• We cannot look up your invoice history, resend an invoice to your client, or tell you what you charged last month.
• We cannot give legal, tax, or accounting advice, or confirm that an invoice satisfies the rules where you are. The guides explain the general practice and say plainly where a question depends on your jurisdiction. For the rest, ask an accountant licensed where you file.
• We cannot chase your client, mediate a payment dispute, or contact anyone on your behalf.

Why there is no contact form

A form needs a server to receive the message, a place to store it, and usually a spam-filtering third party in between. This site has none of those, and adding them would mean the one page where we promise nothing is collected quietly starts collecting things. Email is the honest option: you can see exactly what you are sending and to whom.

Before you write

Two pages answer most incoming mail. The FAQ covers what the tool does, what is saved, and which characters the PDF can show. About covers who we are, how the site is funded, and the features that are deliberately missing. If your question survives both, send it over.
