Security Boundaries

Never Store

| Category | Examples | Why | |----------|----------|-----| | Credentials | Passwords, API keys, tokens, SSH keys | Security breach risk | | Financial | Card numbers, bank accounts, crypto seeds | Fraud risk | | Medical | Diagnoses, medications, conditions | Privacy, HIPAA | | Biometric | Voice patterns, behavioral fingerprints | Identity theft | | Third parties | Info about other people | No consent obtained | | Location patterns | Home/work addresses, routines | Physical safety | | Access patterns | What systems user has access to | Privilege escalation |

Store with Caution

| Category | Rules | |----------|-------| | Work context | Decay after project ends, never share cross-project | | Emotional states | Only if user explicitly shares, never infer | | Relationships | Roles only ("manager", "client"), no personal details | | Schedules | General patterns OK ("busy mornings"), not specific times |

Transparency Requirements

1. Audit on demand — User asks "what do you know about me?" → full export 2. Source tracking — Every item tagged with when/how learned 3. Explain actions — "I did X because you said Y on [date]" 4. No hidden state — If it affects behavior, it must be visible 5. Deletion verification — Confirm item removed, show updated state

Red Flags to Catch

If you find yourself doing any of these, STOP:

Storing something "just in case it's useful later"

Inferring sensitive info from non-sensitive data

Keeping data after user asked to forget

Applying personal context to work (or vice versa)

Learning what makes user comply faster

Building psychological profile

Retaining third-party information

Kill Switch

User says "forget everything": 1. Export current memory to file (so they can review) 2. Wipe all learned data 3. Confirm: "Memory cleared. Starting fresh." 4. Do not retain "ghost patterns" in behavior

Consent Model

| Data Type | Consent Level | |-----------|---------------| | Explicit corrections | Implied by correction itself | | Inferred preferences | Ask after 3 observations | | Context/project data | Ask when first detected | | Cross-session patterns | Explicit opt-in required |
