Privacy Policy for FireFlag

Last Updated: February 4, 2026

Overview

FireFlag is committed to protecting your privacy. This privacy policy explains our data practices for the FireFlag browser extension.

FireFlag collects ZERO personal data.

Data Retention

Material changes will be announced in the extension's release notes.

Compliance

FireFlag complies with:

  • GDPR (EU General Data Protection Regulation)
  • CCPA (California Consumer Privacy Act)
  • Mozilla Add-on Policies
  • Firefox Data Collection Requirements

Since we collect zero data, compliance is straightforward: no data collection means no privacy concerns.

Transparency

FireFlag's privacy commitment is backed by:

  • No server infrastructure: We don't run servers, so there's nowhere for your data to go
  • Open source code: Anyone can verify our privacy claims
  • Formal verification: Core safety components are mathematically proven
  • Mozilla review: Extension is reviewed by Mozilla before publication

Summary: FireFlag collects ZERO data. Everything stays on your device. Your privacy is guaranteed by design, not just by policy.
