Privacy Policy
Last updated: 28 May 2026
PhishGuard ("the extension") is an anti-phishing tool that analyzes web pages before they load in your browser. This policy explains exactly what data it processes, where that data goes, and what it stores.
What the extension processes
When you navigate to a site that is not already trusted or on the built-in list of well-known domains, the extension fetches that page in the background and processes:
- The page's URL and domain.
- The page title.
- The page's HTML and the contents of scripts loaded by the page.
This data is used only to assess whether the page is a phishing, keylogging, or data-theft threat.
Data sent to third parties
To perform the analysis, the extension sends the page content described above to a third-party AI provider — Anthropic, OpenAI, or DeepSeek, depending on configuration. The request is made directly from the extension to that provider's API over HTTPS.
Your use of those providers is governed by their respective privacy policies:
- Anthropic — anthropic.com/legal/privacy
- OpenAI — openai.com/policies/privacy-policy
- DeepSeek — deepseek.com/privacy
The extension does not send your data to any other server, and does not include your browser cookies or login session when it fetches a page for analysis.
What is stored, and where
The following are stored locally on your device using the browser's extension storage, and are never uploaded by the extension:
- Your list of trusted ("whitelisted") domains.
- Your check on/off preferences.
You can clear this at any time by removing the extension or clearing its storage.
What is NOT collected
- No browsing history is logged or transmitted by the extension.
- No analytics, tracking, or advertising identifiers.
- No personal account information.
- Trusted and well-known sites are not fetched or sent anywhere for analysis.
Data retention
The extension itself does not retain analyzed page content after a check completes. Retention of API request data is determined by the AI provider's policy linked above.
Changes
This policy may be updated as the extension evolves. Material changes will be reflected on this page with a new "last updated" date.
