Privacy isn’t an afterthought in Trenddit Memo—it’s fundamental to our design. We believe your data belongs to you, and we’ve built every aspect of our Chrome extension around this principle.

From local-first storage to encrypted API keys, Trenddit Memo gives you full control over your information without sacrificing functionality.

Why Privacy Matters for Knowledge Management

When you capture and organize web content, you’re essentially creating a digital representation of your interests, research, and thought processes. This information is incredibly valuable—and sensitive:

  • Research topics reveal your professional interests and competitive advantages
  • Learning patterns show your skill development and knowledge gaps
  • Content preferences indicate personal values and decision-making processes
  • Question patterns expose strategic thinking and business priorities

Traditional cloud-first tools require you to trust third parties with this intimate data. Trenddit Memo takes a different approach.

Local-First Architecture

Your Computer, Your Data

Everything starts and stays local:

  • All captured content stored on your device using Chrome’s secure storage APIs
  • AI processing results cached locally for offline access
  • No server-side storage of your personal content
  • Complete functionality without internet connection (with local AI)

How Local Storage Works

Content capture and storage:

Web Content → Local Processing → Secure Browser Storage
     ↓                ↓                    ↓
  Extracted     AI Analysis        Encrypted Storage
   Content      & Tagging          Your Device

Benefits of local storage:

  • Instant access: No network delays for content retrieval
  • Offline functionality: Review and search content without internet
  • Privacy guarantee: Content never leaves your device unless you choose
  • Performance: Fast search and filtering of your knowledge base

Optional Cloud Sync

Lightweight metadata only: If you choose to enable Chrome sync, only minimal metadata is shared:

  • Content titles and tags (not full content)
  • Organization structure and categories
  • Basic timestamps and source URLs
  • No AI analysis results or sensitive content

What never syncs:

  • Full text of captured content
  • AI conversation history
  • API keys or provider configurations
  • Personal notes and annotations

Encrypted API Key Management

Zero-Knowledge Key Storage

We never see your credentials:

  • All API keys encrypted before storage using browser’s built-in encryption
  • Keys encrypted with device-specific credentials
  • No transmission of keys to external servers
  • Each provider’s keys stored separately with individual encryption

Secure Key Handling

Browser-level security:

// Simplified security model
API Key → Browser Encryption → Secure Storage → Local Access Only
    ↓              ↓               ↓              ↓
Your Input    Native Chrome    Extension     Direct Provider
              Encryption       Storage       Communication

Security benefits:

  • Device-specific: Keys tied to your specific browser installation
  • Tamper-resistant: Encrypted storage prevents unauthorized access
  • Segmented access: Each AI provider’s keys isolated from others
  • Revocable: Easy to remove or change keys without affecting other data

Privacy-First Features

No Tracking or Analytics

Zero surveillance:

  • No usage analytics or telemetry collection
  • No tracking of websites you visit or content you capture
  • No behavioral profiling or pattern analysis
  • No data sharing with third parties

Granular Privacy Controls

You control every aspect:

  • Provider selection: Choose cloud or local processing per task
  • Sync preferences: Enable or disable metadata sync independently
  • Content filtering: Mark sensitive content for local-only processing
  • Retention control: Set automatic deletion rules for old content

Audit Trail and Transparency

Full visibility:

  • Open source code: Complete transparency in data handling
  • Clear documentation: Detailed privacy policy and data flow diagrams
  • Audit logs: Track what data is processed where
  • Export capability: Get all your data out at any time

Privacy Best Practices

Hybrid Privacy Strategy

Match privacy level to content sensitivity:

Public content (news, general research):

  • Use cloud providers for speed and advanced features
  • Enable sync for cross-device access
  • Benefit from latest AI capabilities

Sensitive content (business strategy, personal projects):

  • Use local AI processing for complete privacy
  • Disable sync for this content
  • Keep processing entirely local

Mixed workflows:

  • Start with cloud processing for initial organization
  • Switch to local processing for sensitive analysis
  • Use tags to manage privacy levels

Organization for Privacy

Privacy-aware tagging:

  • Tag sensitive content for easy identification
  • Create privacy-level categories (Public, Internal, Confidential)
  • Use visual indicators for privacy status
  • Filter by privacy level when needed

Content segregation:

  • Separate work and personal content
  • Use different provider configurations by context
  • Create privacy-focused collections
  • Regular audit of sensitive content

Technical Privacy Implementation

Browser Security Integration

Chrome’s security model:

  • Content Security Policy (CSP) compliance
  • Secure extension sandboxing
  • Native encryption APIs
  • Isolated storage contexts

Zero-Trust Architecture

Assume nothing, verify everything:

  • Each provider connection independently secured
  • No shared credentials between providers
  • Isolated processing contexts
  • Minimal privilege access patterns

Data Minimization

Collect only what’s necessary:

  • Capture only essential content metadata
  • Process only relevant portions of content
  • Store only useful analysis results
  • Regularly clean up temporary data

Privacy Compliance

Regulatory Alignment

Built for compliance:

  • GDPR: Right to deletion, data portability, processing transparency
  • CCPA: Consumer privacy rights and data disclosure
  • HIPAA: Healthcare information protection (with local processing)
  • SOX: Financial data security requirements

Enterprise Privacy

Business-ready privacy:

  • Data residency: Keep data in specific jurisdictions with local processing
  • Access controls: Role-based content access and sharing
  • Audit requirements: Complete processing logs and data lineage
  • Compliance reporting: Generate privacy and security reports

Privacy Without Compromise

With Trenddit Memo, you don’t have to choose between powerful AI features and data privacy:

Privacy without compromise:

  • ✅ Local-first storage keeps your content on your device
  • ✅ Encrypted API keys protect your credentials
  • ✅ No tracking or surveillance of your usage
  • ✅ Full data control with export and deletion capabilities
  • ✅ Granular controls for different privacy levels

Privacy that scales:

  • Start with cloud providers for convenience
  • Gradually move sensitive content to local processing
  • Maintain different privacy levels for different content types
  • Scale privacy controls as your usage grows

For complete privacy, consider using Ollama for local AI processing where no data ever leaves your device.
