Privacy Policy
Last updated: 9 October 2026
WA Privacy is a Chrome extension that blurs content on WhatsApp Web (web.whatsapp.com) so people looking at your screen can't read it, with per-chat visibility settings and an optional PIN lock.
WA Privacy does not send any data to the developer or to any third party. There are no servers, no analytics, no ads and no tracking. Everything described below stays in your browser.
What the extension handles
| Data | Why | Where it is kept |
|---|---|---|
| Chat names shown on WhatsApp Web | To remember which chats you chose to show, and which parts of them | chrome.storage.sync (your Chrome profile; synced by Chrome to your other devices if you use Chrome Sync) |
| Your settings (what is blurred by default, blur strength, hover reveal, pause) | To apply your preferences | chrome.storage.sync |
| App lock PIN | To unlock WhatsApp Web | Only a salted PBKDF2-SHA-256 hash is stored, in chrome.storage.local on this computer. The PIN itself is never stored and is never synced. |
| Last activity time (a timestamp of your last click, key press, scroll or mouse movement on WhatsApp Web) | To lock WhatsApp Web after the inactivity delay you choose | chrome.storage.local on this computer. Only the time is kept, not what you clicked or typed. |
| Page content on WhatsApp Web (names, photos, previews, messages, media) | Read in the page only to apply the blur. It is not stored, copied or sent anywhere. | Not stored |
The extension does not read, store or transmit the text of your messages, your contacts' phone numbers, or any data from websites other than web.whatsapp.com.
Permissions
- storage: saves the settings, chat choices and app-lock data described above.
- scripting: activates the extension in WhatsApp Web tabs that were already open when it was installed or updated, so they are protected without a reload.
- Access to https://web.whatsapp.com/: needed to blur WhatsApp Web and show the lock screen. The extension does not run on any other website.
Sharing and selling
We do not sell, share or transfer any user data. No data is used for advertising, profiling, credit-worthiness or any purpose other than the extension's single purpose described above.
Your control
- Change or remove any chat's settings at any time from the extension's popup.
- Export or import your settings from the popup.
- Removing the extension from Chrome deletes all of its stored data (settings, chat choices, PIN hash and activity timestamp).
Changes
If this policy changes, the updated version will be published on this page with a new date.
