2. Information we collect
We do not collect any of your information through the Extension.
The Extension does not communicate with any external server and has no accounts. It does not include any third-party services for advertising, analytics, tracking or the like.
3. Content of the pages you visit
To display masks, the Extension runs on the web pages (http and https) you open and reads their content. This content is used only to display and restore masks in your browser, and is never sent anywhere.
4. Information stored in your browser
So that masks can be restored the next time you open a page, the Extension stores the following information in your browser (chrome.storage.local):
- The domain of each site where you created masks, and the page path
- Information used to find hidden elements again (CSS selector, element type, the beginning of the element’s text (up to 200 characters) and image URL)
- Text you hide with Select text, and the text just before and after it (up to 24 characters each)
- Each mask’s effect, strength, on/off state and creation time
- The defaults for new masks
Hidden text and similar information are stored unencrypted. Please do not use the Extension to hide passwords or other secrets. This information is never sent anywhere.
5. Why each permission is needed
storage: To store your masks in your browser- Running on web pages (http and https): To display masks over elements and text on the page
6. Sharing with third parties
Because we do not collect your information, we do not share it with any third parties.
7. Deleting your data
- In the Extension’s Settings, you can delete the settings for each site, or all settings
- Removing the Extension from Chrome deletes all stored information
