Questions

Is SharpSharp really free?

Yes. Every tool is free to use as often as you like, with no trial period and no sign-up. Documents you make carry a small SharpSharp watermark unless you choose to have it removed.

How is it free, then?

Tool pages show adverts, and there is an optional small payment if you want documents without the watermark. That is it. Your data is not the product.

What happens to the information I type?

It stays on your own device. The tools work inside your browser, so your figures, names and details are not sent to us or stored on our servers. Close the page and it is gone, unless your browser keeps a draft for you.

Can I use the documents for my business?

Yes. The receipts, invoices, letters and other documents you make are yours to use in your business. You are responsible for checking that what they say is accurate and right for where you work.

Do I need an account?

No. Open a tool, fill it in, download or share the result. No email address, no password, no app to install.

How do I remove the watermark?

Watermark removal is a small one-off payment. You can ask for it through any document tool on the site, and you will be told the price before you pay anything.

Your documents are made in your browser. Names, amounts and anything else you type are never sent to us or stored by us. We count visits and which tools are used, without identifying you, so we know what to improve.
