We collect nothing. GuardianAI does not collect, transmit, or store any personal data on any server, cloud service, or external system. There is no backend. There is no database. There is no analytics service.
The extension operates entirely within your browser. No data leaves your machine at any point during normal operation.
You can verify this yourself: open Chrome DevTools → Network tab → filter by Fetch/XHR while using GuardianAI. You will see zero outbound requests from the extension.
GuardianAI stores the following data locally in your browser using chrome.storage.local. This data never leaves your device.
| Data | What it contains | Why it's stored |
|---|---|---|
| Settings | Extension preferences (threshold, compliance mode, theme, auto-sanitize mode) | To remember your configuration between sessions |
| Custom keywords | Words or phrases you add in the Keywords tab | To detect organisation-specific sensitive terms |
| Audit log | Timestamp, site, risk level, detection types, action taken, browser user agent. Maximum 50 events. Ring buffer — oldest events are overwritten. | To give you a local record of detection events |
| Onboarding flag | A boolean indicating you have completed onboarding | To avoid showing the onboarding screen on every install |
Your prompt text is never stored. The audit log records metadata only — what type of sensitive data was detected and what action you took — never the content of your prompt.
We don't use your data. We can't — we never receive it. All processing happens on your device, by your browser, for your benefit.
The GuardianAI Chrome extension makes no calls to any third-party service. It does not use Google Analytics, Mixpanel, Sentry, or any other analytics, error tracking, or monitoring service.
The GuardianAI website (guardianai.co.za) uses Google Fonts for typography. This means Google's servers receive a request for font files when you visit the website. This is standard practice and subject to Google's Privacy Policy. The extension itself does not load Google Fonts.
The website includes a waitlist form. Email addresses submitted via this form are stored locally in your browser until a real email service is integrated. No email addresses are transmitted to any server at this time.
GuardianAI is built for South African users and is designed to be consistent with the Protection of Personal Information Act (POPIA), Act 4 of 2013.
Since we collect no data, we have nothing to retain. Your local data (settings, keywords, audit log) is retained on your device until you:
Because we hold no personal data about you, most data subject rights (access, correction, deletion, portability) are self-administered through the extension itself. You can:
GuardianAI is not directed at children under the age of 13 (or under 18 in jurisdictions where a higher age threshold applies). We do not knowingly collect any data from children. If you are under the applicable age threshold, please do not use GuardianAI without parental supervision.
If we make material changes to this privacy policy — particularly if we ever introduce server-side data collection — we will update the effective date at the top of this page and notify users via the Chrome extension update mechanism.
Given our local-only architecture, we do not anticipate making changes that would reduce your privacy protections. Any change that involves collecting data we do not currently collect would require explicit opt-in consent.
If you have questions about this privacy policy, or if you believe GuardianAI has handled data in a way that is inconsistent with this policy, please contact us:
