1) The promise

Discreet coordination should feel effortless to the user and defensible to the platform:

• Private by design: conversations stay confidential to participants.

• Consent-forward: every sensitive interaction is explicit, logged, and reversible.

• Legitimate discretion: built to protect users’ privacy—not to enable harm, coercion, or illegal activity.

• Simple UX: “secure” cannot require technical knowledge.

---

2) The problem you’re solving

Users who value discretion (executives, creators, high-profile professionals, members with reputational risk) need a place to:

• coordinate plans privately,

• share sensitive details safely (location, schedules, preferences),

• formalize confidentiality expectations (NDAs),

• reduce exposure to screenshots, leaks, impersonation, and “he said / she said” disputes.

Public social apps are optimized for discovery and virality. Discreet coordination needs the opposite: privacy, verification, boundaries, and accountability.

---

3) Principles that define “how it should work”

A. End-to-end confidentiality (content)

• Message content is protected from third parties and from the platform itself (where feasible).

• Attachments, voice notes, and calls follow the same protection standard.

B. Metadata minimization (context)

• Protect not only what was said, but who talked to whom, when, and how often as much as practical.

• Store the minimum needed to operate safely and resolve disputes.

C. Verified participants

• Discreet systems collapse without identity integrity.

• Verification should be private, tiered, and respectful (not publicly visible).

D. Clear boundaries + safety

• Consent, reporting, blocking, and escalation must be first-class flows.

• NDAs must never be used to silence abuse or wrongdoing.

---

4) Core user flows

Flow 1 — “Start a secure thread”

1. User selects a verified profile → Start Secure Chat

2. Platform confirms: both parties verified + privacy mode enabled

3. Chat opens with:

   • “Confidential by default” header

   • quick controls: Disappearing timer, Screenshot warnings, Lock chat

4. Optional: “Add NDA” appears as a pre-chat gate or in-chat upgrade

UX requirement: the user never has to “turn on” security. They only choose levels of retention and formality.

---

Flow 2 — “Add an NDA without killing the moment”

NDA should be fast, human, and aligned with real intent:

• NDA types

  • Light NDA (social discretion): protects identity, photos, and private details.

  • Standard NDA (events/introductions): adds non-disclosure around plans, locations, companions, gifts.

  • Custom NDA (for high-profile): editable clauses, jurisdiction, term length.

• NDA steps

  1. User taps Add NDA

  2. Select type → preview plain-language summary

  3. Both parties review → e-sign

  4. System issues:

     • time-stamped certificate

     • version hash (prevents “you changed it” disputes)

     • revocation rules (what happens if one party leaves)

Critical guardrail: include explicit carve-outs:

• “This NDA does not restrict reporting harassment, coercion, threats, or illegal activity.”

---

Flow 3 — “Discreet coordination that still feels safe”

Inside the secure chat, coordination tools should be structured (to prevent oversharing and reduce misunderstandings):

• Plans & logistics cards (instead of free-text):

  • Time window (not exact time if user chooses)

  • General area (not exact address unless explicitly shared)

  • “Arrival check-in” toggle

• Selective sharing

  • Location can be shared as:

    • Area-level (neighborhood)

    • Pin for 30 minutes

    • One-time directions

• Safety check-ins

  • Optional “I’m okay” prompts

  • Trusted contact alerting (opt-in, privacy-respecting)

---

5) Security + privacy requirements (product-level, not implementation-level)

A) Message protection

• Strong encryption for messages and attachments.

• Forward secrecy where possible (older messages remain protected even if a key is later compromised).

• Device-level protections:

  • app lock (PIN/biometric),

  • hidden previews for notifications,

  • secure local storage.

B) Retention controls (user-driven)

• Default: disappearing messages with sensible presets (e.g., 1 hour / 24 hours / 7 days).

• “Keep” requires explicit action from both parties (mutual retention).

C) Screenshot + export friction (honest, not magical)

You cannot fully stop screenshots. You can:

• warn users when screen capture is attempted (where OS allows),

• watermark sensitive media (subtle, non-invasive),

• limit forwarding/export,

• educate clearly: “Confidentiality is enforced by agreement and policy, not only technology.”

D) Identity and impersonation defense

• Verified badges (private tiers)

• Secure profile linking (prevents copycat profiles)

• “In-thread verification” prompt for first-time chats (lightweight)

---

6) Trust, safety, and policy (non-negotiable)

Discretion cannot mean “no accountability.” Build safety into the same layer as privacy:

• One-tap block / report

• Evidence bundle (user-consented) for serious cases:

  • allows a user to preserve specific messages before expiry for investigation

• Clear policy:

  • NDAs cannot be used to suppress reports of harm

  • coercion, threats, non-consensual content → immediate enforcement

• Member conduct scoring (private, non-public):

  • repeated reports trigger limits or removal

---

7) Differentiation language (positioning)

Use language that signals premium privacy and responsibility:

• “Confidential by default. Consent by design.”

• “Verified discretion—built for real-world coordination.”

• “Privacy-first, NDA-ready, safety-backed.”

Avoid messaging that implies secrecy for wrongdoing. Replace “untraceable” or “can’t be caught” with “confidential,” “data-minimal,” “member-protected,” “policy-backed.”

---

8) What success looks like (KPIs)

• Secure chat activation rate after introductions

• NDA adoption rate (light vs standard vs custom)

• Incident rate per 1,000 chats (reports, blocks)

• Time-to-sign NDA (median)

• Member trust score improvements over time

• Retention: users who use secure coordination tools vs chat-only

---

9) Recommended feature set (MVP → V1 → V2)

MVP

• Verified members

• Secure chat with disappearing messages

• NDA: Light + Standard templates + e-sign + certificate

• App lock + hidden notifications

• Block/report + safety carve-outs in NDA

V1

• Plans/logistics cards

• Selective location sharing (area vs pin)

• Mutual “keep” for retention

• Media watermarking + screenshot warnings (where supported)

V2

• Custom NDAs (editable clauses)

• Trusted contact safety check-ins

• High-profile mode (extra metadata minimization + stricter controls)
