BlurShield processes everything locally on your device. We do not collect, store, or transmit any personal data or page content. Your browsing activity stays on your device.
This extension does not collect:
The auto-detect feature scans page text using regular expressions to identify sensitive patterns (emails, phone numbers, API keys, etc.). This processing happens entirely within your browser. No page content is ever sent to any server. The extension only applies CSS blur filters to matching elements — it does not read, copy, or store the detected text.
When you save blur configurations, the extension stores only CSS selectors and coordinates (e.g., "div > p:nth-of-type(2)" or "{x: 100, y: 200}") via chrome.storage.sync. The actual text content behind the blur is never saved. This data syncs across your Chrome devices via your Google account.
The extension requests the following permissions, used solely for core functionality:
BlurShield does not request access to all websites. It only operates on the tab you explicitly activate it on.
Pro plan payments are processed by ExtensionPay and Stripe. Payment information is handled entirely by these third-party services and is never accessible to this extension. See their respective privacy policies for details.
The extension communicates with extensionpay.com solely to verify Pro plan subscription status. No browsing data or page content is sent.
If this policy changes, the updated version will be posted here with a new date.
