Legal disclaimer
 
 
DocuJ is provided "as is" and "as available", without warranty of any kind. To the maximum extent permitted by law, DocuJ disclaims all express, implied, and statutory warranties, including merchantability, fitness for a particular purpose, accuracy, non-infringement, and uninterrupted or error-free operation.
 
You are solely responsible for what you do with DocuJ and for the consequences of that use — including having the rights to process your documents, keeping backups, verifying every output before relying on it, and complying with all laws and obligations that apply to you.
 
DocuJ is a document-editing tool and does not provide legal, compliance, or other professional advice. Signatures, redactions, and edits may not satisfy every legal or organizational requirement; verifying that is your responsibility.
 
To the maximum extent permitted by law, DocuJ is not liable for any damages or loss of data arising from your use of the software. Nothing here excludes rights that cannot lawfully be excluded.
 
 
  
 
   
 
Terms of Use
 
 
By using DocuJ you agree to these Terms. DocuJ is a browser-based PDF editor; your documents are processed locally and are not uploaded to us.
 
DocuJ is currently free to use. We may add optional paid plans or features in the future; if we do, their price and terms will be shown before any purchase, and we intend to keep a free tier available.
 
You are solely responsible for your use of the Service and its results, including having the rights to process your documents, keeping backups, verifying output, and complying with the laws and obligations that apply to you. You may not use the Service unlawfully or to infringe others' rights.
 
DocuJ's own code, design, and branding remain ours; you keep all rights in your documents. Bundled open-source components are licensed under their own terms.
 
The Service is provided "as is" without warranties, and our liability is limited to the maximum extent permitted by law. We may update these Terms; continued use means you accept the changes. Questions: contact@docuj.com.
 
 
  
 
   
 
Privacy Policy
 
 
DocuJ processes your PDFs locally in your browser. The documents you open and edit are not uploaded to us — we never see or store their contents.
 
Some non-document resources are downloaded so the app can run, such as the application files and, for OCR, the language data for the language you choose. These never send us your document contents.
 
We use limited Cloudflare analytics to understand aggregate usage and improve DocuJ. Cloudflare Web Analytics measures page views and performance without cookies, persistent identifiers, or cross-site tracking. Where enabled, Zaraz records only feature-action names — never document contents, filenames, form contents, passwords, search terms, or other free text. We do not combine analytics with advertising data, create individual profiles, or send DocuJ events to advertising or marketing services.
 
We do not sell your data, show ads, or require an account. Preferences such as your language are kept in your browser's local storage and are not sent to us.
 
You can contact us at contact@docuj.com to access, correct, or delete any personal data we hold about you (such as emails you send us), or to object to its processing. We keep contact emails only as long as needed to handle your request. You also have the right to complain to the Spanish Data Protection Agency (AEPD).
 
If we add paid plans later, billing will be handled by a third-party processor and this Policy will be updated. Questions: contact@docuj.com.
