Lindy Data Handling

Overview

Lindy agents process data through triggers, LLM calls, actions, knowledge bases, and memory. Data flows through Lindy's managed infrastructure with AES-256 encryption at rest and in transit. This skill covers data classification, PII handling, prompt-level data controls, and regulatory compliance.

Prerequisites

• Understanding of data types processed by your agents
• Knowledge of applicable regulations (GDPR, CCPA, HIPAA)
• For HIPAA: Business Associate Agreement (BAA) with Lindy (Enterprise plan)

Lindy Data Architecture

Instructions

Step 1: Classify Data in Agent Workflows

Map what data each agent processes:

Step 2: PII Controls in Agent Prompts

Add data handling instructions directly to agent prompts:

## Data Handling Rules
- Never include full email addresses in summaries — use "[name]@[domain]"
- Redact phone numbers in logs — show only last 4 digits
- Do not forward customer personal information to Slack channels
- When storing to spreadsheet, omit columns: email, phone, address
- If asked to share customer data externally, decline and escalate

Step 3: Knowledge Base Data Safety

Knowledge base files are searchable by the agent. Control what goes in:

DO upload:

• Product documentation
• FAQ articles
• Policy documents
• Public knowledge articles

DO NOT upload:

• Customer databases with PII
• Credentials or API keys
• Internal HR documents (unless agent specifically needs them)
• Financial records with account numbers

Resync considerations: KB auto-refreshes every 24 hours. If you upload sensitive content by mistake, remove it AND trigger a manual Resync.

Step 4: Secure Memory Usage

Agent memories persist across all future tasks. Be deliberate:

Safe memory: "Customer prefers email communication over phone"
Safe memory: "Billing questions should escalate to finance@company.com"

Risky memory: "John Smith's SSN is 123-45-6789"  ← NEVER store PII in memory
Risky memory: "API key for Stripe: sk_live_xxxx"  ← NEVER store secrets

Add to agent prompt:

## Memory Rules
- Never store personally identifiable information (PII) in memory
- Never store credentials, API keys, or passwords in memory
- Memories should contain preferences, patterns, and procedures only

Step 5: Computer Use Data Isolation

If using Computer Use (browser automation):

• Sessions persist for 30 days with saved credentials
• Enable Incognito mode for sessions handling sensitive data
• Use dedicated (not shared) computer assignments for sensitive agents
• Review screenshots captured during execution for data exposure

Step 6: Integration Account Isolation

• Authorize dedicated service accounts per agent (not personal accounts)
• Use Gmail with a team alias, not an individual inbox
• Create read-only database credentials where possible
• Revoke access immediately when an agent is decommissioned

Step 7: Regulatory Compliance

GDPR (EU Data Protection):

• Document what personal data each agent processes
• Ensure agents only process data with valid legal basis
• Implement data subject access/deletion capabilities
• Agent prompt includes "do not retain personal data beyond task completion"
• Review Lindy's data processing agreement

CCPA (California Consumer Privacy):

• Identify agents processing California resident data
• Ensure opt-out mechanisms exist for data processing
• Agent prompt prevents selling/sharing personal information

HIPAA (Healthcare):

• Enterprise plan with BAA in place
• Agents only access minimum necessary PHI
• No PHI in agent memory or knowledge base
• Audit trail enabled for all PHI access
• Agent prompt includes PHI handling restrictions

Step 8: Data Retention Management

Agent Prompt Addition:
## Data Retention
- Do not reference data from tasks older than 30 days
- Clear task context after each run (do not accumulate indefinitely)
- When updating memory, remove outdated entries
- Summarize customer interactions, do not store verbatim transcripts

Data Handling Checklist

• Each agent's data classification documented
• PII handling rules in every agent prompt
• Knowledge base audited for sensitive content
• Memory creation restricted (no PII, no secrets)
• Integration accounts isolated per agent
• Computer Use sessions set to dedicated + incognito where needed
• Regulatory compliance requirements mapped
• BAA in place if handling healthcare data
• Data retention policy defined and enforced in prompts
