Page access

The extension needs page access to place blur overlays on top of sensitive areas. That access is used locally for the current browsing experience.

Storage

Chrome storage remembers preferences, site presets and Pro status. Some preferences and site presets use storage.sync and follow your Chrome synchronization settings. Replacement scenarios, subscription credentials, the per-profile installation identifier and the daily analytics marker use storage.local.

Network calls

The extension contacts Supabase for subscription verification, intentionally submitted support requests and, from version 2.7.3, optional product analytics after explicit consent. Upgrade links open the website paywall. Analytics are forwarded server-side to PostHog; the PostHog SDK is not included in the extension. Screen content is not uploaded for blur processing.

Manifest V3 technical breakdown for security reviewers

Screen Privacy Blur requests activeTab, tabs, scripting, storage and sidePanel. These let it identify the target tab, apply bundled protection code, remember settings and keep controls beside the page. The existing https://*.supabase.co/* host permission supports backend requests. Optional site permissions are requested for replacement scenarios that must remain protected across page reloads. Version 2.7.3 does not add permissions or host permissions for analytics.

How to prepare before sharing

When setting up Why Screen Privacy Blur needs browser permissions (Browser Permissions Guide | Screen Privacy Blur), Screen Privacy Blur runs 100% locally in your Chromium browser so private records, credentials, and financial balances remain hidden or replaced with realistic demo data before any frame is shared.

  1. Open the browser tab or desktop context you plan to present.
  2. Place blur overlays over the private fields that can appear during the walkthrough.
  3. Review the visible area, then start the call or recording.
