Terms of use

Terms

The rules of the road for using PopDF, in plain language.

Draft for review: these terms must be reviewed by Liquid Technology's legal adviser before PopDF opens to the public. Last updated 5 November 2026.

1. Who you're dealing with

PopDF is provided by Liquid Technology Limited, registered in Malta (C105818), Tagliaferro Business Centre, Sliema, Malta. By creating an account or using PopDF you agree to these terms.

2. The service

PopDF lets you send PDF documents for electronic signature, sign documents sent to you, and download a sealed copy with a certificate of completion. Documents are encrypted in your browser; we can't read them.

3. Your account

Give accurate details: they appear on the certificates of documents you sign, and are kept in your browser. Signing needs no account. Sending needs your email address confirmed with a code we email you; you may also set up an account to keep your documents in a list on every device, protected by a passkey or recovery code that only you hold. Keep your recovery code safe: we can't recover it. You're responsible for your device and for keeping your links private.

4. Links and keys

Anyone holding a PopDF link can open that envelope. Share links only with the intended person, and keep your owner link safe. We can't recover lost links or keys, and we can't recover a popped envelope. Download your sealed copy before your envelope pops.

5. Acceptable use

Don't use PopDF for anything unlawful, fraudulent or harmful; to impersonate anyone; to send malware; or to overload or probe the service except through our security disclosure process. We may suspend access to stop abuse.

6. Legal effect of signatures

PopDF provides simple electronic signatures. You're responsible for deciding whether that's suitable for your document. Some documents, such as wills, deeds that need witnessing or documents requiring qualified electronic signatures, need a different process. We don't give legal advice.

7. Plans and pricing

PopDF is in beta. Plans, limits and beta pricing are shown on the pricing page and may change. Paid plans will be opt-in and announced at least 30 days before any charge applies.

8. Availability and liability

We work hard to keep PopDF running but provide it "as is" during early access. To the extent the law allows, we're not liable for indirect or consequential losses, or for losses caused by lost links, expired or popped envelopes, or documents you chose to sign. Nothing in these terms limits liability that can't legally be limited, including for consumers' statutory rights.

9. Changes and ending

You can stop using PopDF at any time. We may update these terms; we'll give notice of material changes in the app.

10. Our software and brand

PopDF's software, design and name belong to Liquid Technology Limited and are protected by copyright and other intellectual property law. You may use PopDF as we offer it. You may not copy, modify, decompile or reverse-engineer its code (except where the law allows you to regardless), redistribute or resell it, use it to build a competing service, or use the PopDF name or look for your own products. The open-source components PopDF includes (such as pdf.js, pdf-lib, fontkit, mammoth, Tiny Little Office and the Noto fonts) remain under their own licences, which you can read with the files themselves.

11. Law

These terms are governed by the laws of Malta, and the courts of Malta have jurisdiction, without affecting any mandatory consumer protections where you live.
