Privacy Policy

No Personal Data Stored
No User Tracking
Anonymous Analytics Only

BothLang is built with privacy as a core principle. We understand that your language preferences and browsing activity are personal. That's why we've designed our service to work entirely locally with minimal data collection.

Our Promise

We collect only what's necessary to improve our service and provide you with the best translation experience. No personal information, no browsing history, no content tracking.

What We DON'T Collect

Here's what we absolutely do not collect, store, or have access to:

  • Personal Information: No names, emails, usernames, or any identifying information
  • Content: We never store or transmit the content you translate
  • Browsing History: We don't track which websites you visit
  • Translation Content: The text you translate stays on your device and is never sent to our servers
  • User Accounts: We don't link any data to your accounts or browser profile
  • Location Data: No GPS, IP address tracking, or location-based information
  • Device Information: No device fingerprinting, hardware specs, or system information

Important Note

All translations happen using third-party translation APIs (Google Translate, Edge Translate) or local processing. We simply display the results - no content passes through our servers unless you explicitly use our AI translation service.

  • Translation attempts (success/failure rates)
  • Language pairs (e.g., English → Vietnamese)
  • Extension installation/updates
  • Feature usage patterns

❌ What We DON'T Track

  • Your username or account information
  • Content you translate
  • Personal browsing patterns
  • IP addresses or location
  • Device or browser fingerprints
  • Cross-site tracking

Data Retention

Local Storage (Your Device)

The extension stores minimal settings locally on your device:

  • Language Preferences: Your chosen source and target languages
  • Extension Settings: UI preferences and configuration
  • Session Data: Temporary data that's cleared when you close your browser

Analytics Data

Anonymous usage statistics are retained according to Google Analytics' data retention policies:

  • Default Retention: 26 months for analytics data
  • No Personal Data: Since we don't collect personal information, there's nothing personal to retain
  • Aggregated Only: All data is aggregated and cannot be traced back to individuals

Your Privacy Rights

Since we don't collect personal data, traditional data rights (like deletion requests) don't apply. However, you have complete control:

  • Uninstall Anytime: Remove the extension to stop all data collection immediately
  • Local Data Control: Clear your browser data to remove any local settings
  • Opt-out of Analytics: Use browser extensions that block Google Analytics if desired
  • Transparency: This privacy policy explains everything we collect

GDPR & Privacy Laws

Our minimal data collection approach means we're compliant with GDPR, CCPA, and other privacy regulations by design. We don't collect personal data, so there's no personal data to protect, process, or delete.

Third-Party Services

We use Google Analytics to understand service usage. Google's privacy policy applies to this data:

  • Purpose: Anonymous usage statistics and improvement insights
  • Data: Only anonymous, aggregated usage patterns
  • Control: You can block Google Analytics with browser extensions

Translation Providers

When you translate content, the extension uses third-party translation services:

  • No Intermediary: We don't intercept or process the translation requests
  • Provider Policies: Each provider's privacy policy applies to their services

  • Notification: We'll update the "Last Updated" date below
  • Significant Changes: Major changes will be announced through the service
