Your content stays local
No WhatsApp content, browsing history or extension telemetry is sent to the developer.
Privacy by design

Privacy at a glance
The important facts, first.
Three verified facts explain how the extension handles your WhatsApp content, processing and settings.
Blur runs in the page
Supported WhatsApp Web elements are changed visually inside your browser.
Only settings use storage
Preferences use Chrome storage; temporary lock state stays in local extension storage.

Extension data collection
Privacy Blur for WhatsApp Web is the website brand for the extension whose manifest name is “WhatsApp Web Privacy Blur — Hide Chats, Names & Media.” It is designed to operate without collecting or sending WhatsApp messages, contact or group names, profile photos, media files, phone numbers, chat metadata, browsing history, analytics events, tracking data, or extension telemetry to the developer.
In practical terms
The extension has no developer-operated content backend.
Local processing on supported pages
The extension runs content scripts on https://web.whatsapp.com/* and
https://business.whatsapp.com/*. These scripts inspect page elements only
as needed to apply visual blur, hover reveal, and local lock behaviour.
All visual changes happen within the browser page where the supported WhatsApp interface is open.
Chrome extension storage
The extension uses two Chrome-provided storage areas for different purposes:
chrome.storage.sync
Stores privacy preferences such as enabled protections, blur strength, appearance, and password-lock settings. If password lock is configured, the extension stores a locally generated SHA-256 password hash rather than the plain-text password.
chrome.storage.local
Stores the temporary locked/unlocked state on the current browser installation.
Depending on your Chrome account and sync settings, Google Chrome may sync values from
chrome.storage.sync across browsers where you are signed in. This syncing is
provided by Chrome, not by a server operated by the extension developer.
Chrome extension storage contains settings only; WhatsApp messages, photos, media and files are not written there.
Password Lock is a local visual gate
It does not encrypt WhatsApp chats, authenticate your WhatsApp account, replace device or account security, or prevent screenshots. The plain-text password is not stored.
Why each Chrome permission is requested
The current extension manifest requests storage and access to the two supported WhatsApp domains.
The manifest does not request browsing-history, camera, microphone, location, cookies, or all-sites access.
Website hosting and connection data
The privacyblur.in website is hosted on Netlify. To deliver and secure the
website, the hosting provider may process standard connection and security information,
such as an IP address, browser user agent, request time, and requested URL.
This is website-delivery data handled under the hosting provider's practices. Visiting this website does not grant it access to your WhatsApp chats.
Support email and correspondence
When you email privacyblur.support@gmail.com, your email address, message, attachments, and normal email metadata are processed by your email provider and by Google/Gmail. The Privacy Blur developer/publisher receives the information you choose to include so the request can be answered or investigated.
Support correspondence may be retained as needed to respond, diagnose issues, and maintain appropriate support records. You may request deletion by emailing the same address, subject to legitimate security, record-keeping, or legal needs. Avoid sending private WhatsApp content unless it is necessary for your request.
External links
Links to the Chrome Web Store, WhatsApp, email services, or other third-party websites take
you outside privacyblur.in. Those services may process standard service,
connection, or account data according to their own terms and privacy policies. Privacy Blur
does not control those third-party practices.
Analytics and third-party services
The current Privacy Blur extension and privacyblur.in website do not include
developer-operated analytics, advertising, telemetry, or error-reporting SDKs. The extension
also does not include payment services, authentication services, or external content-processing APIs.
Hosting, browser, email, Chrome Web Store, and WhatsApp providers may independently process standard service data under their own terms and privacy practices. Their processing is not developer-operated Privacy Blur analytics.
Privacy Blur does not currently offer Pro checkout or licensing on this website, and the website does not collect payment details. This policy will be updated before any paid service or payment provider is introduced.
Data retention and control
Extension data
Preferences remain in Chrome extension storage until they are changed, reset, removed by the browser, or affected by your Chrome sync and account settings.
Support correspondence
Emails and attachments may be kept as needed to answer the request, diagnose issues, maintain appropriate records, and meet legitimate security or legal needs. You may ask for deletion by contacting support.
Website connection and security data may be retained by the hosting provider according to its own practices and settings.
Policy updates
This policy may be updated if extension functionality, permissions, storage behaviour, or external-service usage changes. The “Last updated” date at the top of this page will identify the current version of the policy.
