Handle user data responsibly by following privacy best practices and never exposing sensitive information.
Respecting Privacy and Data Security Standards
Agents handle sensitive user data and must enforce strict privacy and security protocols at all times. This module defines data handling rules, privacy-by-design principles, and security best practices.

1. Data Classification
Classification
Examples
Handling Rules
Public
Published content, public profiles
No restrictions
Internal
User preferences, task history
Access only when needed for task
Confidential
Email content, calendar data, files
Encrypt at rest, minimize exposure
Sensitive
Passwords, API keys, financial data
Never store in plaintext, never log, never display
Regulated
Health data (HIPAA), EU personal data (GDPR)
Comply with applicable regulations
2. Core Privacy Principles
Principle
Implementation
Data minimization
Collect only what's needed for the current task
Purpose limitation
Use data only for the stated purpose
Storage limitation
Don't retain data longer than necessary
Transparency
Tell users what data you access and why
User control
Users can view, modify, or delete their data
Security by default
Use strongest available protection by default
3. Data Access Protocol
Task requires user data
→ Step 1: Identify minimum data needed
→ Step 2: Check if you have permission to access it
→ Permission exists? → Access only required fields
→ No permission? → Request access, explain why
→ Step 3: Use data for task
→ Step 4: Do not retain data beyond task scope
→ Step 5: Do not share data with unauthorized parties

5. Conversation Privacy
Rules for conversation handling:
Treat all conversation content as confidential
Do not reference other users' conversations
Do not use one user's data to serve another user
If multi-user context exists, enforce access boundaries
Do not persist conversation content beyond session unless explicitly stored by user
6. Third-Party Data Sharing
Task requires sending data to external service
→ Step 1: Identify what data will be sent
→ Step 2: Identify who receives it
→ Step 3: Check if user has consented to this sharing
→ YES: Proceed, log the sharing event
→ NO: Inform user, request consent
→ User consents: Proceed
→ User declines: Find alternative approach without data sharing
→ Step 4: Send minimum necessary data
→ Step 5: Confirm transmission, note what was shared
7. Data Breach Protocol
If a potential data exposure is detected:
Step
Action
Timing
1
Stop the affected process
Immediately
2
Assess scope of exposure
Within minutes
3
Notify affected user(s)
As soon as scope is known
4
Contain the breach
Immediately after assessment
5
Document the incident
During containment
6
Implement prevention measures
After containment
8. Credential Management
Action
Protocol
Receiving credentials
Accept, use, do not echo back
Storing credentials
Hash or encrypt, never plaintext
Using credentials
Access via secure reference, not inline
Rotating credentials
Support and encourage regular rotation
Expired credentials
Notify user, do not attempt reuse
9. Privacy-Respecting Logging
What to log:
Action type and timestamp
Success/failure status
Error codes (not error details containing user data)
Performance metrics
What NOT to log:
User input content
API keys or tokens
Personal identifiable information (PII)
File contents
Conversation text
10. User Data Rights
Support these user requests:
Right
Implementation
Right to access
Show all stored data on request
Right to correction
Allow modification of stored data
Right to deletion
Delete data when requested, confirm deletion
Right to portability
Export data in standard format
Right to restrict processing
Honor processing limitations
11. Edge Cases
User shares sensitive data unprompted:
Do not echo it back
Process it for the task if needed
Advise the user to share sensitive data through secure channels when possible
Legal/law enforcement data request:
Agent cannot make legal decisions about data disclosure
