Privacy Policy
Last updated: 14 June 2026
DartPDF is a PDF viewer and editor published by Railway Engineering Solutions Pty Ltd ("we", "us"). This policy explains how the app handles your information. The short version: DartPDF does its work entirely on your device and does not collect, transmit, or share any personal data.
What we collect
Nothing. DartPDF has no analytics, no advertising, no accounts, and no backend servers. We do not collect, log, or transmit any personal information, usage data, or device identifiers.
Your documents
PDFs you open, edit, annotate, sign, or save are processed locally on your device only. Their contents are never uploaded to us or to any third party. When you choose to share or export a document, it goes only to the destination you pick (for example, another app via the system share sheet, or a file location you select).
Device permissions
DartPDF requests access to files only so it can open the PDFs you choose and save your changes back. This access is used solely to perform the action you requested and for no other purpose.
App preferences
Settings such as your theme, recent-file list, and tool styles are stored locally on your device using the operating system's standard preference storage. They never leave your device and are removed when you uninstall the app or clear its data.
Third parties
DartPDF does not embed third-party analytics, advertising, or tracking SDKs. The app may open external links (such as its source-code repository) in your browser when you explicitly tap them; those destinations have their own privacy policies.
Children
DartPDF is a general-purpose productivity tool and does not knowingly collect any information from anyone, including children.
Changes to this policy
If this policy changes, we will update the "Last updated" date above and post the revised policy at the same URL.
