Terms of use
Last updated: 14 October 2026 · Apply to pdfsigna.com and to the PDFsigna applications.
Nothing is on sale today. The Windows application is out on the Microsoft Store and the macOS one is in Apple review; version 1.0 is free on both. Section 5 applies now. A paid Pro plan is only a possibility, with no date: the purchase terms in section 6 would apply if it ever exists, and today there is no purchase to govern.
1. What these terms are
These terms govern access to and use of the pdfsigna.com website and use of the PDFsigna applications for macOS and Windows. By using the site you accept them; if you don’t agree with them, don’t use it.
2. Who provides the service
The site and the applications are operated by Color Vivo Internet, S. L. You can contact us at support@pdfsigna.com or through the support page. Its tax ID, registered address and the other details required by article 10 of Spanish Law 34/2002 are in the legal notice.
3. Using the website
The site is informational. You may read it, link to it and quote it. You may not use it for unlawful purposes, interfere with its operation, or extract its content in bulk in a way that degrades the service for others.
We take reasonable care to keep the site available and accurate, but we do not guarantee that it is always reachable or free of error. Third-party prices shown in the comparisons were verified on the date stated in each table and may have changed since; the source is each vendor’s public website.
4. Intellectual property
The PDFsigna name, logo, icons, illustrations, text and site design belong to their owner. You may quote excerpts with attribution and a link, as is customary. You may not reuse the brand or the design to present another product as if it were this one.
Other product names mentioned here — Adobe Acrobat, PDF Expert, DocuSign, Signaturit, AutoFirma and the rest — are trademarks of their respective owners and are cited for comparative and informational purposes. PDFsigna is not affiliated with Adobe or FNMT, or with any of the others.
5. Application licence
The applications are licensed as follows:
- A licence to use, not a sale of the software. You acquire a personal, non-transferable right to use the application, with no time limit.
- No paid licences today. Version 1.0 is free. If a Pro licence is ever offered — a possibility we’re considering, with no date — its actual terms will be published here and on the store before it can be bought. Our intention, not a commitment, is that a one-time purchase wouldn’t expire and would include updates, that any yearly option would stay optional, and that nothing already paid for would be taken away.
- What you sign stays signed. Documents you sign with the application stay signed even if you stop using it: the signature lives in the PDF.
- No account. Using the application requires no registration or identification of any kind.
- You may not decompile, redistribute or sublicense the application, except to the extent the law expressly allows and does not permit to be excluded by contract.
If the application is acquired through a store — the Mac App Store or the Microsoft Store — that store’s terms apply in addition, and its policy governs payment, refunds and updates.
6. Price and purchase
The price
PDFsigna version 1.0 is free. A paid Pro licence is on our roadmap as a possible option; there is no date and no commitment. If it happens, its price will be published on the store before it can be bought. No checkout is open today.
Where to buy
Only through the Mac App Store and the Microsoft Store. This website sells nothing and charges nothing, and there is no other sales channel. If there is ever something to buy, the purchase — and a subscription, should one exist and you choose it — would go through your store account, under that store’s terms.
Refunds and withdrawal
Because the purchase relationship is with the store, refunds and the right of withdrawal are handled by the store — Apple for the Mac App Store, Microsoft for the Microsoft Store — under its own terms, and you request them there. Those terms are theirs and can change, which is why this page does not copy their time limits. Nothing in this section limits the rights consumer law gives you.
7. Warranties and liability
The applications will be supplied in conformity with consumer law, which these terms neither exclude nor limit. Beyond that, the software is provided as is: we do not warrant that it is fit for a particular purpose or free of defects.
And one warning that matters more than the usual formula: PDFsigna is a tool that produces and verifies electronic signatures, but it does not determine the legal validity of a specific document in a specific situation. The level it reports describes what kind of signature was produced, based on the certificate used and where its key is held; what effect that has in a given proceeding depends on the jurisdiction, on the type of document, and on who receives it. That needs legal advice, and this page is not it.
We are not liable for damage arising from use contrary to these terms, for the unavailability of third-party services needed in order to sign — timestamping authorities, revocation services or trusted lists — or for loss of documents from causes outside the application. Nothing in this section limits liability where the law does not permit it to be limited.
8. What PDFsigna is not
- It is not approved or certified by the European Union. No such approval exists for applications, and anyone advertising one is saying something that means nothing.
- It is not a qualified trust service provider. Certificates are issued by third parties and timestamps by a timestamping authority; PDFsigna uses them, it does not issue them.
- A visual signature is not an advanced electronic signature. That is the distinction the product rests on, and it is not relaxed even here.
9. Changes
These terms may change. When they do, the date at the top changes. If a change affects a purchase already made, the terms in force at the time of that purchase apply.
10. Governing law
These terms are governed by Spanish law. If you are a consumer, that choice does not deprive you of the protection of the mandatory rules of the country where you live, nor of the right to bring proceedings before the courts of your own domicile.
