Privezap, Privacy for WhatsApp Web, by Privezap, adds a visual privacy layer to WhatsApp Web to reduce casual onlooker exposure in public and shared workplaces. It masks interface elements and supplies quick-access concealment gestures while keeping all processing local. Key controls include element-specific blurring, a decoy Boss Key, and automatic locking. The tool targets professionals, students, and anyone using WhatsApp Web where screen privacy matters.

Who benefits most when using Privezap in shared locations?

Privezap is aimed at people who open WhatsApp Web where others can glimpse the screen, for example in open offices, classrooms, or during presentations. The extension’s workflow focuses on preventing accidental visual disclosures while the user continues normal chat activity. That positioning addresses the practical problem of shoulder-surfing rather than account-level privacy or server-side data controls.

How granular is the visual protection over WhatsApp Web elements?

The extension provides element-level obfuscation so different parts of the interface can be concealed independently. Controls let you tune blur intensity and the extension supports a hover gesture to reveal a blurred item briefly for discreet checks. A local settings panel exposes these options and stores lightweight usage statistics on the device only, so adjustments are under the user's control.

What assurances does Privezap provide about data handling and authentication?

Privezap processes data entirely on the user's machine and does not use remote servers for storage or analytics. Local credentials are protected with PBKDF2 hashing for stored unlock material, and an intruder protection mode temporarily pauses access after repeated failed attempts. Those choices keep authentication and telemetry confined to the desktop environment where WhatsApp Web runs.

How does the extension behave during interruptions and active use?

A single Boss Key shortcut, Ctrl+Shift+X, swaps the page to a discreet notes view for immediate concealment. Automatic locking can trigger on inactivity, tab switches, or window minimization so the screen returns to a locked state without manual steps. The extension accepts password or PIN unlocks, offers light and dark themes for the overlay, and installs on Chrome and other Chromium-based browsers.

Best suited to users who need quick, local screen privacy

Built by an independent, privacy-focused developer, Privezap is a practical choice for people who frequently show WhatsApp Web where others can glance at the display. It centers control on the desktop rather than changing account settings. A recommended preparatory step is to mute or disable desktop message notifications so pop-up alerts do not surface outside the browser view during meetings or shared sessions.
