Privacy Policy

1. Introduction

StopLight ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our AI-powered email classification service.

2. Information We Collect

Account Information

When you sign up for StopLight, we collect:

• Full name
• Email address
• Preferred inbox provider (Gmail, Outlook, or Yahoo)

Email Data

When you connect your inbox, our AI accesses your email content solely for classification purposes. We process:

• Email sender information
• Email subject lines
• Email body content (processed in real-time, then discarded)
• Email metadata (timestamps, read/unread status)

Usage Data

We collect behavioral data to improve our AI classification:

• How you interact with classified emails (reply, archive, reclassify)
• VIP sender designations
• Gamification activity (XP, streaks, badges)

3. How We Use Your Information

• Email Classification: To assign RED, YELLOW, or GREEN priority tiers using our GPT-4o-mini pipeline
• AI Summaries: To generate 1–2 sentence email summaries
• Self-Learning: To adapt classification to your preferences over a 30-day behavioral loop
• Security: To scan links via Google Safe Browsing API
• Gamification: To track XP, levels, streaks, and achievements

4. Data Security

We take data security seriously:

• OAuth 2.0: We authenticate via OAuth — we never see or store your email password
• PII Scrubbing: Personal identifying information is automatically scrubbed before AI processing
• Data Minimization: Email content is processed for classification and immediately discarded. Only metadata and AI-generated summaries are retained
• Encryption: All data in transit is encrypted via TLS 1.3

5. Data Sharing

We do not sell, rent, or share your personal data with third parties for marketing purposes. We may share data only with:

• Service Providers: OpenAI (for AI classification), Google (for Safe Browsing API) — under strict data processing agreements
• Legal Requirements: When required by law or to protect our rights

6. Your Rights

You have the right to:

• Access your personal data
• Request correction or deletion of your data
• Disconnect your inbox at any time
• Export your data
• Opt out of behavioral learning

7. Data Retention

Email content is processed in real-time and not stored. AI-generated summaries and metadata are retained for the duration of your account. Upon account deletion, all data is permanently removed within 30 days.
