JustOpenFile

Privacy Policy

Last updated: June 2025

Overview

JustOpenFile is a purely client-side file viewer. All file processing happens entirely in your browser — no files are ever uploaded to our servers.

Data We Do Not Collect

  • Files you open or drag into the viewer — they never leave your device.
  • File contents, names, or metadata.
  • Personal information such as name, email, or account details. No account is required.

Proxy Feature

When you use the optional proxy to open a remote URL, the file is streamed through our server to bypass browser CORS restrictions. We do not log, store, or inspect the content of proxied files. The data is streamed directly and discarded immediately after delivery.

Analytics

We may collect anonymous usage analytics (page views, feature usage) to improve the service. This data does not include any file content or personally identifiable information.

Cookies

We do not use cookies for tracking or advertising. A minimal session cookie may be used for language preference.

Third-Party Services

We do not share data with third parties. The service has no ads, no tracking pixels, and no social media integrations.

Changes to This Policy

We may update this policy from time to time. The date at the top of this page reflects the most recent revision.
