Privfox Screen privacy

Your presentation habits stay on your Mac.

Privfox Screen is designed so its core privacy features do not require an account, a server, or a reason to send your data anywhere.

What Privfox Screen stores locally

Privfox Screen stores only the settings needed to work: onboarding completion, your Safe Apps list (bundle identifiers and display names), companion appearance preferences, the emergency-shortcut configuration, and whether optional alerts are enabled. These values are saved locally using macOS UserDefaults.

What Privfox Screen does not collect

Permissions in plain language

Basic Safe Apps alerts use standard macOS workspace activation notifications. That lets Privfox Screen learn only which app became frontmost so it can compare its bundle identifier with your Safe Apps list.

No Accessibility permission is required for the basic workflow.

Presentation Mode, Safe Apps alerts, the Privacy Curtain, and the supported global shortcut work without Privfox Screen reading screen content or observing typed text.

Optional website links

The Get updates control opens privfox.com/updates in your default browser. Privfox Screen does not collect your email address or make newsletter requests itself. The updates page will explain the mailing provider and its data use before signup is enabled.

Website support form

If you contact Privfox through the website, we receive the information you choose to submit: your email address, optional name, selected topic, and message. Formspree processes and temporarily stores the submission so it can be delivered to Privfox. Cloudflare processes the request, IP address, and Turnstile security signals to prevent automated abuse. The private Turnstile key and support destination are not placed in the public website code.

Formspree's current free plan retains submission history for 30 days. Privfox retains a support message in the receiving inbox only as long as reasonably needed to answer the request, investigate a report, maintain necessary records, or prevent abuse. Do not submit passwords, private screen contents, meeting links, or other information that is not needed for support.

Your choices

You can remove Safe Apps, turn alerts off, change the shortcut, disable the fox, and clear the app's local settings from within the app. Removing Privfox Screen removes its local application data along with the app.

Changes to this page

Because Privfox Screen is open source, material privacy changes will be documented in release notes and in the source repository before a release is published.
