Clipboard Guard is a security tool that intercepts and blocks websites from reading your clipboard without permission. It uses two content scripts: interceptor.js runs in the MAIN world to override navigator.clipboard.readText() and navigator.clipboard.read(), while content.js runs in the ISOLATED world to show toast notifications and manage your whitelist. Clipboard Guard does not read your clipboard contents itself — it only prevents other sites from doing so. It does not communicate with any external server.
None. Clipboard Guard collects zero personal information. No names, emails, IP addresses, browsing history, clipboard contents, or behavioral data are ever collected, stored externally, or transmitted anywhere.
Clipboard Guard stores the following data exclusively on your own device using Chrome's storage APIs. This data never leaves your browser.
| Key | What it stores | Purpose |
|---|---|---|
| enabled | Boolean toggle for whether clipboard interception is active (synced via chrome.storage.sync) |
Lets you enable or disable protection across devices |
| whitelist | List of domains you have explicitly allowed to read the clipboard (synced via chrome.storage.sync) |
Permits clipboard access on sites you trust |
| eventLog | Last 50 clipboard access events: domain, allowed/blocked status, and timestamp (stored in chrome.storage.local) |
Shows recent activity log in the popup so you can see which sites attempted clipboard access |
storage
Used to persist your whitelist and enabled preference via chrome.storage.sync, and the event log via chrome.storage.local. Data is stored only on your device (sync data may sync across your Chrome profile if enabled in Chrome settings).
host_permissions (<all_urls>)
Required to run content scripts on all websites so clipboard access attempts can be intercepted regardless of which site you visit. The MAIN world script overrides clipboard read APIs. The ISOLATED world script handles UI notifications and whitelist management. Neither script reads your clipboard contents, page text, user input, or any personal data.
Clipboard Guard does not use analytics, crash reporting, advertising SDKs, or any third-party service. There are no external API calls. All interception logic is bundled inside the extension itself.
Clipboard Guard does not load or execute any code from remote servers. All JavaScript is bundled in the extension package that you install from the Chrome Web Store.
Clipboard Guard is not directed at children under 13. We do not knowingly collect any information from children.
If we update this policy, the new version will be posted at this URL. The effective date at the top will be updated accordingly. Continued use of the extension after changes constitutes acceptance of the updated policy.
