Privacy Policy

1. Information We Collect

1.1 Analytics Data

We collect anonymous usage analytics to improve our service, including:

• Page views and navigation patterns
• Search queries (origin and destination toll plazas)
• Device type and browser information
• Geographic location (city/region level only)

1.2 Session Data

We assign anonymous session IDs to understand user interactions. Session IDs are:

• Randomly generated and stored locally in your browser
• Not linked to any personally identifiable information
• Used solely for analytics and improving user experience
• Automatically deleted when you clear your browser data

2. Voice Assistant Privacy

2.1 How Voice Recognition Works

• Browser-based processing: Voice recognition uses your browser's built-in Web Speech API (provided by Google Chrome, Microsoft Edge, or Safari)
• No audio recording: We never record, store, or have access to your voice audio
• Transcript only: The browser converts your speech to text locally, and only the text transcript is processed
• Privacy by design: The microphone automatically stops after each query result

2.2 What We Receive

When you use the voice assistant, we receive only:

• Text transcripts: The written form of what you said (e.g., "Balintawak to Clark")
• Extracted data: Origin plaza, destination plaza, and vehicle class
• Search metadata: Timestamp, session ID, and whether the query succeeded

We never receive or store:

• Your voice audio recordings
• Your name, phone number, or email address
• Your exact GPS location
• Any personally identifiable information

2.3 Text-to-Speech (TTS) Audio

When we speak toll results aloud:

• We use OpenAI's text-to-speech API to generate audio (e.g., "The toll is 467 pesos")
• Generated audio is cached in Supabase public storage for faster repeat queries
• Cached audio contains no personal information—only toll amounts and plaza names
• Cache files are publicly accessible but anonymous (no user linkage)

2.4 Your Voice Privacy Rights

• Opt-out anytime: Simply don't use the voice assistant feature. The manual calculator is always available.
• Control microphone access: Your browser will ask for permission before accessing your microphone. You can revoke this anytime in browser settings.
• No voice profiles: We do not build voice profiles, voiceprints, or any biometric identifiers.
• Automatic stop: The microphone stops immediately after showing your result. We never listen in the background.

3. How We Use Your Data

• Provide toll calculations: Process your queries (voice or manual) to show accurate toll fees
• Improve accuracy: Analyze failed queries to enhance plaza name matching
• Analytics: Understand which routes are most popular to prioritize features
• Performance optimization: Monitor response times and error rates

We do not:

• Sell your data to third parties
• Use your data for advertising
• Share your data with marketers
• Build user profiles for tracking across websites

4. Data Storage and Security

• Database: Search queries and analytics are stored in Supabase (PostgreSQL) with encryption at rest
• Retention: Analytics data is retained for 90 days, then anonymized or deleted
• Access control: Only authorized administrators can access analytics data
• HTTPS: All data transmission is encrypted using industry-standard SSL/TLS

5. Third-Party Services

We use the following third-party services:

• Google Web Speech API: Browser-based voice recognition (Google's privacy policy applies)
• OpenAI TTS API: Text-to-speech audio generation (OpenAI's privacy policy applies)
• Supabase: Database and storage (Supabase's privacy policy applies)
• Vercel: Hosting and deployment (Vercel's privacy policy applies)

6. Cookies and Local Storage

We use browser local storage (not cookies) to:

• Store your anonymous session ID
• Remember your theme preference (light/dark mode)
• Cache frequently used data for faster loading

You can clear this data anytime in your browser settings under "Clear browsing data" → "Local storage."
