PageShield Privacy Policy
Effective Date: 3 August 2025
Overview
PageShield is a Chrome extension that helps users identify and manage hidden or suspicious elements on websites, such as invisible iframes and overlapping buttons. This privacy policy explains how PageShield handles data and ensures user privacy.
What PageShield Does
PageShield scans the webpage currently open in your browser for elements that may be invisible, overlapping, or otherwise deceptive. It notifies you when suspicious elements are detected and provides options to highlight, block, or whitelist them. You may also optionally run an AI-based scan to evaluate risk. It additionally blocks known advertising domains.
What Data Is Accessed or Used
PageShield does not collect or share any personal information on user activity. All data processing is done locally in your browser. The extension temporarily accesses the following information for the purposes described:
Suspicious HTML (such as iframe or button code) is analyzed in memory only. It is not stored or transmitted unless an AI scan is triggered.
If you activate an AI scan, PageShield sends the current page URL and suspicious element HTML to a third-party AI model hosted by OpenRouter.ai. This data excludes cookies, login details, form input, and personal identifiers. PageShield does not have any access to the IP address information or details of any requests which are sent through OpenRouter. OpenRouter's privacy policy states that they do not collect, store or sell any data from requests routed through it.
Your settings—such as whether the extension is enabled, your strictness level, and any whitelisted iframe sources—are saved locally using Chrome’s extension storage system.
AI Scanning
PageShield includes two types of optional AI-based evaluations:
Preliminary Scan: Automatically runs after detection and sends the page URL and stripped HTML of suspicious elements to an AI model. It returns a flag/ignore result and a numeric risk score.
Full AI Scan: Manually triggered by the user, sending the same kind of data and receiving a short text explanation.
These scans are only performed when detection occurs or when triggered by the user. No private information is included.
Tracker Blocking
PageShield uses a curated list of known ad and tracking domains to block network requests using Chrome’s built-in blocking API. This occurs entirely in the browser. No external data collection or syncing occurs.
What PageShield Does Not Do
PageShield does not collect names, emails, passwords, or any personally identifiable information.
PageShield does not use cookies or fingerprinting techniques.
PageShield does not track your browsing history. PageShield does not have any servers or databases with any user's browsing history, whatsoever.
PageShield does not send background data to any remote server, except when you explicitly trigger an AI scan.
PageShield does not serve ads or share data with advertisers.
PageShield does not track or monitor users over time after installation. PageShield only counts the number of installs, and the geographic location from which the installs come from. Additionally, PageShield counts which type of Browser (Chrome, Edge) the extension was installed on.
User Control
Users may:
Enable or disable PageShield at any time
Adjust the detection strictness level
Whitelist iframe sources
Clear all saved data from the extension popup
Minimal Analytics
When the extension is first installed, PageShield sends a single anonymous pageview to GoatCounter, a privacy-focused analytics tool. This is used solely to monitor total installation activity. No IP addresses, cookies, or personal data are recorded at all.
Permissions Requested
PageShield uses the following Chrome permissions:
activeTab: To analyze the current page only
storage: To save local settings and preferences
declarativeNetRequest: To block known trackers locally
host_permissions: "*://*/*": To allow detection across all visited websites
These permissions are used only for functionality described in this policy and never for personal tracking or data collection.
Policy Updates
This policy may be updated in the future. If updates are made, they will be published at:
