thedixitjain 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
| Component | Data Storage | Retention |
|---|---|---|
| Tasks | Task inputs, outputs, step data | Visible in dashboard |
| Memory | Persistent snippets across tasks | Until manually deleted |
| Context | Per-task accumulated context | Task lifetime only |
| Knowledge Base | Uploaded files, crawled sites | Until manually removed |
| Integrations | OAuth tokens, connection data | Until disconnected |
| Computer Use | Browser session, screenshots | 30 days after last use |
Instructions
Step 1: Classify Data in Agent Workflows
Map what data each agent processes:
| Data Category | Examples | Handling |
|---|---|---|
| Public | Product info, FAQs, pricing | No restrictions |
| Internal | Sales reports, meeting notes | Limit to authorized agents |
| Confidential | Customer emails, CRM data | Access controls + audit |
| Restricted | PII, PHI, payment data | Minimize exposure + compliance |
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
Error Handling
| Issue | Cause | Solution |
|---|---|---|
| PII in Slack channel | Agent forwarded customer email | Add "never forward PII to Slack" to prompt |
| Sensitive file in KB | Uploaded by mistake | Remove file + trigger KB resync immediately |
| Memory contains PII | Agent auto-created memory | Delete memory + add "never store PII" to prompt |
| Audit finding | Agent accessing unnecessary data | Remove unused integrations from agent |
