Synergy through structure

Intentional living and meaningful connections. Structure your relationships, activities, and experiences — they become more than the sum of their parts.

Kensic helps you track activities, nurture relationships, pursue interests, and reflect on experiences. Unlike social media, it's private by design.

🔒

Privacy First

Your data stays on your device by default. Cloud backup is optional and encrypted. No ads, no tracking, no selling your social graph.

📄

10 Frame Types

Journal entries, pros & cons, reading lists, playlists, decision trees, life events, medical notes, quotes, and more. Each frame type is purpose-built — not just a blank text box.

📡

Bluetooth Broadcasting

Broadcast your presence to melded friends via BLE. Your ID rotates every 15 minutes to prevent tracking. Two modes: Melded Only (friends) or Everyone (open discovery).

🤖

AI Assist

Chat with Claude to reflect on your journal, get suggestions for activities, or brainstorm plans. Your data stays local — AI conversations are private and never stored on our servers.

The stuff that makes you go "wait, it does that?"

Every feature above is backed by systems that work quietly in the background. Here's what powers it all.

🗺️

The Smart Map

Five modes that turn your map into a living record of your life and community.

📍

Activity Logging

The default mode. Log what you're doing, who you're with, and where you are. GPS detects nearby saved places and suggests companions via Bluetooth.

🔍

Explorer Mode

See everywhere you've ever been. Skyrim-style discovery markers show visited vs. unvisited places, visit counts, and gaps in your neighborhood.

🏘️

Neighborhood Trends

Rich neighborhood profiles with written narratives, community-uploaded photos, and per-category activity counts. See what makes each neighborhood unique — its character, its popular spots, and what people actually do there.

🔥

Kensic Heat Map

Animated weekly heat distribution showing where people in your city are active — by interest category. See which neighborhoods are buzzing for coffee, fitness, nightlife, or culture right now.

🛡️

Stingray Shield

Real-time cell tower monitoring that detects IMSI catchers (fake cell towers used for surveillance). Alerts on suspicious tower behavior, network downgrades, and rapid tower changes. (Android only, Night tier)

🤝

Meld

Exchange profiles, interests, and places with someone standing right in front of you. No accounts, no friend requests.

📱

Tap to Connect

Hold phones together to exchange profiles via NFC or Bluetooth. You choose what to share — interests, places, contact info — and what stays private.

📡

Nearby Detection

BLE scanning runs in the background, detecting melded friends nearby. Kensic suggests them as activity companions automatically — no app-opening required.

🔄

Broadcast Presence

Broadcast your presence to nearby friends via Bluetooth. Two modes: Melded Only (visible only to people you've melded with) or Everyone (open discovery). Your broadcast ID rotates every 15 minutes.

Set It & Forget It

Systems that work in the background while you live your life.

📅

Calendar Sync

Import calendar events as activities with one tap. Pair events with people, interests, and places. Your planned life and your real life in one view.

🎯

Goals & Streaks

Set personal goals like "run 3x per week" or "try a new restaurant monthly." Kensic evaluates your activity log automatically and nudges you when you're falling behind.

📊

Discover Feed

Personalized suggestions based on your activity patterns. Rediscover dormant interests, reconnect with friends you haven't seen, and find trending activities near you — powered by anonymous community data.

🔐

Your Data Passport

Bring your life in. Take it with you. Share what you want.

📥

Import Tools

Pull in your history from Google Takeout, Instagram, Apple Maps, contacts, calendar, and notes apps. Don't start from scratch — bring your life with you.

📤

Data Export

Export everything you've built — people, places, activities, journal entries, stats. It's your data. Take it anywhere, anytime.

📎

.kensic File Sharing

Send activity invites and share loose activities as portable .kensic files. Recipients open them in the app and everything slots into place.

Your data, your control

We built Kensic with privacy as the foundation, not an afterthought. Every feature is designed to protect you.

🏠

Local First

All data lives on your device. You're not the product—you're the customer.

🔑

End-to-End Encrypted

When you do use cloud features, everything is encrypted with keys only you control.

🚫

Zero Tracking

No analytics, no behavioral profiling, no selling your data to third parties. Ever.

🔐 Privacy Mode & Access Control

  • Private Tag System — Mark any person, place, activity, or frame as "Private." Hidden from all views until you unlock Privacy Mode.
  • 5-Digit PIN Protection — 100,000 possible combinations. Required on app open, optional on Privacy Mode activation/deactivation.
  • PIN-on-App-Open — Lock the entire app behind your PIN. No one gets past the splash screen without it.
  • PIN-on-Activate — Require PIN to turn Privacy Mode ON (prevents accidental activation).
  • PIN-on-Deactivate — Require PIN to turn Privacy Mode OFF (prevents unauthorized viewing of private content).
  • Auto-Privacy Tagging — Automatically tag all new records (people, activities, locations) as Private by default.
  • Four-Finger Emergency Activation — Long-press with 4 fingers anywhere in the app for 1.5 seconds to instantly activate Privacy Mode.
  • Privacy Screen (Android) — When Privacy Mode is active, app content is hidden from recent apps/task switcher and screenshots are blocked (FLAG_SECURE).

🛡️ Threat Protection

  • Escalating PIN Lockout — 10 failed PIN attempts = 24-hour lockout. Then 3 days, 6 days, 9 days, and so on. Exponential deterrent against brute force.
  • Front Camera Capture Night — After 5 failed PIN attempts, silently photograph the intruder using the front-facing camera. Stored securely for evidence.
  • PIN Lockout Persistence — Lockout periods survive app restarts and device reboots. Can't bypass by uninstalling.
  • Stingray Shield (Anti-Spoofing) Night — Real-time cell tower monitoring detects IMSI catchers (fake cell towers). (Android only — iOS does not expose cell tower APIs.) Alerts you when suspicious cell behavior is detected: network downgrades, rapid tower changes, abnormal signal patterns, and more.

🔒 Encryption & Data Security

  • AES-256-GCM Encryption — Military-grade authenticated encryption for all private data. Industry-standard cipher with tamper detection.
  • PBKDF2 Key Derivation — Your PIN is never stored. Instead, it derives an encryption key using PBKDF2-HMAC-SHA256 with 100,000 iterations (OWASP standard).
  • Encrypted Cloud Backups — If you enable cloud backup, your entire database is encrypted client-side before leaving your device. We never see your plaintext data.
  • Encrypted Meld History — All records of who you've melded with (device IDs, timestamps, profile IDs) are encrypted with your Privacy PIN.
  • Encrypted Error Logs — Error logs (for debugging) are encrypted with AES-256-GCM and auto-deleted after 3 days. Only shared with Sentry if you opt in via bug reports.
  • Secure Data Deletion — When you delete data, it's securely removed from the encrypted SQLCipher database to prevent forensic recovery from disk blocks.

📡 Broadcast & Sharing Security

  • Meld via NFC — Tap phones to exchange encrypted profiles and interests. No accounts, no friend requests, no cloud middleman.
  • Meld-Gated Broadcast — Share location updates, activities, and moments ONLY with people you've physically melded with. Everyone else sees nothing.
  • Broadcast UUID Cycling — Your broadcast ID rotates every 15 minutes to prevent tracking by passive listeners.
  • Broadcast Encryption Night — All broadcast packets are AES-256-GCM encrypted with keys exchanged during Meld. Afternoon tier uses hash-based filtering only.
  • Meld Filter (Receiver) — Automatically hide broadcasts from anyone you haven't melded with, even if they somehow got your device ID.

🔨 Release Build Hardening

  • Code Obfuscation — Dart code symbols are obfuscated in release builds to prevent reverse engineering of the APK/IPA.
  • Debug Symbol Separation — Debug symbols are stripped from release builds and stored separately for crash reporting (Sentry).
  • ProGuard/R8 (Android) — Additional obfuscation and minification for Android release builds.

🏗️ Infrastructure & Architecture

  • Local-First Storage — All data lives on your device in an encrypted SQLCipher database. No mandatory cloud sync.
  • Zero Analytics — No analytics SDKs, no behavioral tracking of any kind. We don't know what you do in the app.
  • No Third-Party SDKs — No ad networks, no social login tracking pixels, no data brokers. Just Supabase (for optional backups/auth) and Google Maps (for places).
  • Content Moderation (Broadcast Only) — Report abuse in broadcast content. Moderation applies ONLY to broadcast features, never to your private data.

"Is this overkill?"

Yes. This is the security equivalent of bringing a tactical nuke to a water gun fight.

But you'll be glad when the day you actually need it all arrives. Most apps give you a padlock emoji and call it "secure." We give you an entire fortress.

Why I built this

I spent five years in behavioral health—crisis stabilization, wraparound services, rehabilitative mental health. I watched people struggle to make sense of their relationships and reflect on what mattered, using tools that were never designed for that.

Moving into healthcare analytics showed me how systems shape behavior, and how most apps claim to help people while actually serving ad revenue and engagement metrics.

🔍

Tools Don't Work

Journaling apps feel sterile. Social media feels performative. Nothing captures the texture of real relationships.

📊

People Need Structure

People want to reflect, grow, and connect—but they need structure that respects autonomy, not algorithms that exploit attention.

🔒

Privacy Is Non-Negotiable

Every app wants to own your data and monetize your social graph. Documenting your life shouldn't mean surrendering control of it.

So I built Kensic the way it should have existed all along: local-first, privacy-respecting, and designed around how people actually think and relate.
