Privacy Policy

Last updated: April 16, 2026

1. Introduction

At OncePDF (a product of Lumewise Technology), accessible from oncepdf.com, we prioritize the privacy of our visitors. This Privacy Policy document contains types of information that is collected and recorded by OncePDF and how we use it. We are committed to processing data strictly within the boundaries of international privacy regulations, including GDPR and CCPA.

2. Log Files and Analytical Data

OncePDF follows a standard procedure of using log files. These files log visitors when they visit websites. The information collected by log files includes internet protocol (IP) addresses, browser type, Internet Service Provider (ISP), date and time stamp, referring/exit pages, and possibly the number of clicks. These are not linked to any information that is personally identifiable. The purpose of the information is for analyzing trends, administering the site, tracking users' movement on the website, and gathering demographic information.

3. Cookies and Web Beacons

Like any other website, OncePDF uses "cookies". These cookies are used to store information including visitors' preferences, and the pages on the website that the visitor accessed or visited. The information is used to optimize the users' experience by customizing our web page content based on visitors' browser type and/or other information.

You can choose to disable cookies through your individual browser options. To know more detailed information about cookie management with specific web browsers, it can be found at the browsers' respective websites.

4. Google DoubleClick DART Cookie

Google is one of the third-party vendors on our site. It also uses cookies, known as DART cookies, to serve ads to our site visitors based upon their visit to oncepdf.com and other sites on the internet. However, visitors may choose to decline the use of DART cookies by visiting the Google ad and content network Privacy Policy at the following URL – https://policies.google.com/technologies/ads

5. Third-Party Advertising Partners

Third-party ad servers or ad networks use technologies like cookies, JavaScript, or Web Beacons that are used in their respective advertisements and links that appear on OncePDF, which are sent directly to users' browsers. They automatically receive your IP address when this occurs. These technologies are used to measure the effectiveness of their advertising campaigns and/or to personalize the advertising content that you see on websites that you visit.

Note that OncePDF has no access to or control over these cookies that are used by third-party advertisers.

6. Browser-Native Data Sovereignty

Unlike traditional PDF editors, OncePDF operates on a "Privacy-by-Design" architecture. The vast majority of document processing (including OCR, sanitization, and rendering) occurs locally within your browser's environment. This means your sensitive documents are never uploaded to our servers for these operations. In the event a server-side helper is required, all data is encrypted in transit and at rest, and is purged from our systems within 60 minutes of completion.

7. GDPR Data Protection Rights

We would like to make sure you are fully aware of all of your data protection rights. Every user is entitled to the following:

  • The right to access – You have the right to request copies of your personal data.
  • The right to rectification – You have the right to request that we correct any information you believe is inaccurate.
  • The right to erasure – You have the right to request that we erase your personal data, under certain conditions.
  • The right to opt-out – You have the right to object to our processing of your personal data.

8. Children's Online Privacy Protection

Another part of our priority is adding protection for children while using the internet. We encourage parents and guardians to observe, participate in, and/or monitor and guide their online activity. OncePDF does not knowingly collect any Personal Identifiable Information from children under the age of 13.

9. Legal Entity and Contact
