Policy Guard Firefox

Policy Guard

Reads Terms of Service and Privacy Policies and tells you what to be cautious about — before you agree. Flags concerns on policy pages and on signup forms, always quoting the exact clause it found. Works offline. AI analysis optional.

Features & Capabilities

Nobody reads Terms of Service. Policy Guard reads them for you and says what is worth being cautious about — before you click "I agree". On a policy page, a small panel appears in the corner with what it found: data sharing, AI training on your content, automatic renewal, arbitration clauses, class action waivers, and ten other categories. Each concern is in plain language, and each one shows the exact sentence it came from. On a signup form — the moment that actually matters — it flags the policies you are being asked to accept, and can read them for you without you leaving the page or opening them. Every finding cites the document. Press "Show on page" and it scrolls to the clause and selects it. A concern with no sentence behind it is not shown at all. Good terms are reported too. If a policy lets you delete your data, keeps your content ownership, or promises not to sell your information, it says so. A list of only bad news is not an honest reading. What runs by default Pattern matching. It is instant, free, works offline, and sends nothing anywhere. That is the whole extension unless you choose otherwise. Optional AI analysis For a closer reading you can add your own Anthropic API key. It is off by default, never runs on its own, and tells you what a scan will cost before you spend anything — roughly $0.02 to $0.09 per policy, paid directly to Anthropic. Results are cached, so the same document is never paid for twice. Anything the AI claims that cannot be found word-for-word in the policy is discarded rather than shown to you, and the extension reports how many findings it threw away. About the permissions Policy Guard reads page text to work out whether a page is a policy. That happens on your device and nothing is transmitted. Access to Anthropic's API, and permission to fetch a policy linked from a form, are both optional and are requested only when you turn those features on. Not legal advice. Policy Guard can miss things, and it is no substitute for reading anything that genuinely matters to you. Source code: https://github.com/Grandizas/PolicyGuard

Is Policy Guard Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Policy Guard requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details
  • Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
  • High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****
Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Policy Guard is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.

Risk likelihood analysis details
  • High This extension was recently updated in the past month. New updates may not be stable or safe.
