Privacy Policy

Version-Specific Privacy

Web Application (pda-i.com)

The web version operates on a zero-tracking, local-first architecture:

• No analytics or telemetry
• No advertisements
• No third-party tracking scripts
• All data stored locally in your browser

Android Free Version (Google Play)

The free Android app includes Google AdMob advertisements which collect and process user data:

• Google Advertising ID tracking
• Device information (model, OS version)
• IP address and approximate location
• Ad interaction data (views, clicks)
• Third-party ad network tracking

Android Premium Version ($2 In-App Purchase)

Upgrading to premium removes all advertisements and ad tracking:

• AdMob SDK disabled after purchase
• No advertising ID collection
• Google Play billing data only (transaction record)
• Same local-first architecture as web version

Advertising & Tracking (Android Free)

The free Android version uses Google AdMob for advertising. This involves significant data collection:

Data Collected by AdMob

• Advertising ID: Unique identifier for ad targeting
• Device Information: Make, model, OS version, screen size
• IP Address: For geolocation and fraud prevention
• App Usage Data: Time spent, features used
• Ad Interactions: Views, clicks, conversions
• Crash Data: Anonymous crash reports for stability

Third-Party Ad Partners

Google AdMob may share data with third-party advertising networks:

• Ad exchanges and demand-side platforms
• Analytics and measurement partners
• Fraud prevention services

See Google's privacy policy: https://policies.google.com/privacy

Opting Out of Personalized Ads

Android users can opt out of personalized advertising:

• Settings → Google → Ads → Opt out of Ads Personalization
• Visit: adssettings.google.com
• Or upgrade to Premium ($2) to remove all ads

In-App Purchases & Billing

The Android app uses Google Play In-App Billing for the $2 premium upgrade:

Data Collected for Billing

• Google Account: Email and user ID for purchase verification
• Transaction Data: Purchase timestamp, price, product ID
• Payment Information: Handled entirely by Google Play (we never see payment details)
• Receipt Data: Stored locally to verify premium status

Payment processing is managed by Google Play. See their privacy policy: Google Payments Privacy

Data Storage & Encryption

Local Storage (All Versions)

Core application data is stored locally on your device using localStorage and encrypted storage:

• Notes: Stored locally, unencrypted (plain text)
• AI API Keys: Encrypted with AES-256-GCM before storage
• AI Conversations: Encrypted with AES-256-GCM before storage
• Conversation Groups: Encrypted with AES-256-GCM before storage
• Theme Preferences: Stored locally, unencrypted
• Keyboard Settings: Stored locally, unencrypted
• Premium Status (Android): Purchase receipt stored locally

Android Application

The Android version adds:

• Google OAuth Tokens: Encrypted and stored locally
• Ad Preferences (Free): Managed by Google AdMob SDK

Note: Health tracking features were removed in version 1.5.6 to simplify permissions.

Third-Party Services

PDA-i integrates with external services only when you explicitly authorize them:

Google Services (Optional - All Versions)

When you sign in with Google, we request limited OAuth scopes:

• Google Calendar: Read-only access to view your calendar events
• Gmail: Full access to read, compose, and send emails
• Google Tasks: Full access to manage your tasks
• Google Contacts: Read-only access to view contacts

Data Flow: Google → Your Device. We never store your Google data on our servers.

AI Services (Optional - All Versions)

When you configure AI chat functionality, you provide your own API keys for:

• Anthropic (Claude): Messages sent directly from your device to Anthropic's API
• OpenAI (GPT): Messages sent directly from your device to OpenAI's API

Data Flow: Your Device → AI Provider. Subject to their privacy policies.

Google AdMob (Android Free Only)

Advertisements served by Google AdMob in the free Android version:

• Collects device and behavioral data
• Shares with third-party ad networks
• Personalized based on Google Advertising ID
• Removed immediately upon premium purchase

What We Don't Collect

Web Version & Android Premium

These versions operate on a zero-telemetry philosophy:

• No Usage Analytics: We don't track how you use the app
• No Crash Reports: No automatic error reporting
• No Location Data: We never access your GPS or location
• No Device Fingerprinting: No tracking across sessions
• No Cookies: No tracking cookies or third-party scripts
• No Server-Side Accounts: No user accounts on our servers
• No Marketing Data: No email lists, no remarketing pixels

Android Free Version

Important: The free Android version collects data via Google AdMob as described above. Premium upgrade removes all advertising tracking.

Network Communications

All Versions

PDA-i communicates over the network when:

• You explicitly sign in to Google (OAuth flow)
• You sync with Google services (Calendar, Gmail, Tasks, Contacts)
• You send messages to AI services (with your own API keys)
• You fetch RSS feeds (direct connection to feed sources)

Android Free Additional Communications

• Ad Requests: To Google AdMob servers for ad delivery
• Ad Tracking: Impression and click data to ad networks
• Billing Verification: To Google Play for in-app purchase validation

All communications use HTTPS encryption. We operate no backend servers—there's nothing to hack because there's nothing stored centrally.

• Google Services: Data syncs to Google's global infrastructure
