Privacy Policy

Last updated: August 2026 · Plain-English summary for the Guardian Angel browser extension

Your API keys stay on your computer. We do not operate a Guardian Angel server that collects your keys or inbox.

Email content is only sent when you click “Check This Email.” Nothing is read automatically in the background.

Who we are

Guardian Angel is a browser extension that helps users review Gmail messages for possible scam or phishing risk. This policy describes how the extension handles information.

What is stored on your device

Your Groq and/or Google Gemini API keys (so you do not have to re-enter them)
Which AI provider you selected
Optional local scan history (last 10 checks: subject, score, recommendation) — stored only on that device

This data is stored using the browser’s local extension storage. It is not uploaded to a Guardian Angel backend.

What is sent when you scan an email

When you click Check This Email, the extension reads the open Gmail message and sends:

Sender
Subject
Email body text (length-limited)

…to the AI provider you selected:

Groq — requests go to Groq’s API (api.groq.com)
Google Gemini — requests go to Google’s Generative Language API

Those companies process the text to return a safety score and advice. Their own privacy policies and terms apply to that processing. Guardian Angel does not receive a copy of your email content on a separate developer server.

What we do not do

We do not sell your data
We do not use your email content for advertising
We do not read your inbox in the background
We do not require an account on a Guardian Angel website to use the extension

Permissions

The extension requests only what it needs:

Storage — save settings and keys on your device
Active tab / scripting — read the Gmail message you are viewing when you ask for a check
Host access — Gmail in the browser, plus Groq and Google AI API endpoints

AI limitations

Results are produced by third-party AI models and can be wrong. Do not treat a “safe” score as a guarantee. When unsure, do not click links or send money; contact the company using a phone number you already know, or ask someone you trust.

Children

The extension is not directed at children under 13. It is intended as a practical safety aid for adults, including older adults and their families.

Changes

If this policy changes in a meaningful way, the “Last updated” date above will be revised. Continued use of the extension after changes means you accept the updated policy.

Contact
