How Mortui Works

Mortui watches how you use your phone. When that pattern stops in a way that looks like more than a quiet week, it asks you to check in. If you don’t, it can ask someone you trust to check on you — and only then does it do what you asked it to do.

The Problem We Solve

Most people leave behind files they never wanted read, and things they never got to say. When someone passes away or becomes incapacitated, this digital estate often remains unmanaged.

Mortui addresses these challenges by providing an intelligent, automated solution for digital estate management — ensuring your digital wishes are carried out exactly as intended.

  • Privacy violations from accessible sensitive data
  • Security risks from unprotected accounts
  • Important messages never delivered to loved ones
  • Digital clutter that persists indefinitely
“Deliver what must be said, destroy what must be forgotten.”
Mortui's guiding principle — ensuring your digital legacy aligns with your wishes.

The Four Phases of Mortui

From initial learning to action execution, Mortui operates through a carefully designed process.

Behavioral Learning Phase

During the initial 14-21 day training period, Mortui learns your unique behavioral patterns by continuously monitoring:

App Usage

Which apps you use, when, and for how long

Device Patterns

Screen unlocks, screen-on duration, typing activity

Physical Activity

Daily step count from the step-counter sensor

Circadian Rhythms

Sleep patterns and daily usage timing

Statistical Analysis Engine

Using advanced statistical methods, Mortui creates a baseline "behavioral fingerprint" unique to you. The system employs:

  • Equal weighting — every behavioral signal carries the same share of the score, so no single metric can carry a verdict on its own
  • Z-Score analysis — measures how many standard deviations current behavior deviates from baseline
  • Direction matters — a drop in activity is what raises concern, and unusually high activity counts as evidence you are fine. Timing signals such as when you first unlock your phone are scored in both directions
  • Weekday/weekend separation — separate baselines for different day types
  • Rebuildable, never self-adjusting — the baseline never drifts on its own, because a slow decline in activity would simply become the new normal. If your routine genuinely changes, Rebuild Baseline relearns it from your last few months of recorded behaviour with no retraining period and no gap in coverage

Anomaly Detection & Triggers

When behavior deviates from your baseline, Mortui weighs it against two thresholds:

Suspicious

2.5+ standard deviations for 2+ consecutive days triggers a manual check-in prompt.

Critical

3.5+ standard deviations escalates fastest — but still needs a second consecutive suspicious day. No single unusual day can trigger anything.

Someone can check on you first

You can add up to three emergency contacts and verify each one — they get a single text from your phone explaining that you listed them. Then, if a countdown runs four hours with no check-in, each receives one more text asking them to call you or check on you. The moment you check in, everyone who was texted gets an all-clear.

With a verified contact in place, the grace period stretches to twelve hours whenever the battery allows, so a person has time to reach you before anything irreversible happens. Emergency contacts never receive your files or final messages — only the request to check on you.

This step is optional. With no contacts added, Mortui goes from the check-in alert straight to the countdown, and everything else works exactly the same.

Fail-Safes Built In

  • Duration-based airplane mode skip — brief toggles don't suppress analysis
  • Vacation mode pause — manually pause monitoring during travel
  • Recovery detection — prevents false triggers when behavior normalizes
  • Battery dead handling — accounts for device being powered off

Secure Action Execution

Based on your pre-configured preferences, Mortui can execute a range of actions. Some actions require the full version. Estate delivery is by email only — if you named emergency contacts, they are never sent your files or messages.

Secure File Deletion Free

Three-pass overwrite — random data, zeros, then ones — flushed to disk and then deleted. Combined with Android’s file-based encryption, the content is not practically recoverable.

Message & File Delivery Paid

Send final messages, files, and instructions to designated recipients via Gmail/Outlook OAuth. Attach encrypted vault files to deliver passwords, account info, or documents alongside your message.

Encrypted File Vault Paid

Store sensitive files in an on-device AES-256-GCM encrypted vault. Import files, build CSV spreadsheets, or create key-value tables with built-in templates for passwords and account credentials. Vault files are encrypted at rest using Android Keystore keys.

Privacy-First Design

All behavioral data remains on your device. Zero cloud storage. No third-party analytics.
