Frequently Asked Questions
Honest answers to the questions that matter most.
Mortui doesn't make a snap judgment. It follows a deliberate, multi-step process designed to minimize false positives before any action is taken.
Anomaly Detection
The app continuously collects behavioral data — app usage, screen activity, physical movement, and circadian rhythms — in 15-minute intervals. Every day at 2 AM UTC, it compares your recent behavior against your established baseline using statistical analysis.
Consecutive Suspicious Days
A single anomalous day won't trigger anything. The app requires multiple consecutive days of significant deviation from your normal patterns before it considers escalating. This filters out sick days, vacations, and forgetful weekends.
Grace Period
If the threshold is met, Mortui doesn't immediately execute. It starts a 4-hour grace period and sends a full-screen alert to your device — waking the screen, showing over the lock screen, and bypassing Do Not Disturb. All you need to do is check in with your PIN or biometrics to cancel.
Check-in Cancels Everything
Checking in at any point — through the alert itself, or just by unlocking the app — immediately cancels the grace period and clears the alert. If you don't check in and the grace period expires, the app verifies one final time that no check-in occurred before proceeding.
Phased Execution
Only after all checks fail does Mortui execute your configured actions — and it does so in a deliberate order. File deletions run first, ensuring sensitive data is destroyed. Then messages are delivered to your designated recipients. Each action runs independently, so a failure in one doesn't block the others.
Mortui supports both biometrics and PIN — but we strongly recommend setting up a PIN, and here's why.
Consider the scenario Mortui is built for: you're incapacitated, or worse. If someone has physical access to your body, they potentially have access to your fingerprint or face. A fingerprint can be pressed to a sensor. A face can be held up to a camera. Biometrics authenticate who you are — but they can't verify that you're the one choosing to authenticate.
A PIN lives only in your head. It can't be extracted from an unconscious or deceased person. No one can hold your hand to a keypad and guess the right sequence. This makes it the most reliable way to prevent someone from opening Mortui and disabling your configured actions — deleting the files you wanted destroyed, cancelling the messages you wanted sent, or viewing what you've set up.
Biometrics are still available as a convenience for everyday use. But when it comes to the moment that matters most, a PIN is the lock that only you can open.
Mortui uses pure statistical analysis — z-scores, variance-inverse weighting, and baseline profiling — instead of machine learning or AI. This is a deliberate choice, not a limitation.
Transparency. Statistical methods are deterministic and explainable. When Mortui flags something as anomalous, you can trace exactly why: which metric deviated, by how much, and against what baseline. There's no black box. No hidden weights. No model that "just decided" your behavior was suspicious.
Privacy. AI models — especially good ones — need training data. That means either sending your behavioral data to the cloud for processing, or running a resource-heavy model on-device. Mortui does neither. The math runs locally, efficiently, and never needs to phone home. Your patterns stay on your device, period.
Reliability. Statistical baselines adapt to your actual behavior over time using established mathematical principles. They don't hallucinate, overfit to noise, or degrade unpredictably after an update. The same input will always produce the same output — which is exactly what you want from an app that might one day decide whether to execute your final wishes.
No dependencies. No model files to download or update. No inference engine to maintain. No risk of a third-party model change altering how your behavior is interpreted. The analysis engine is self-contained, auditable, and will work the same way years from now as it does today.
Yes — always.
Mortui is a one-time purchase, but updates are delivered through Google Play just like any other app on your device. When we ship a bug fix, security patch, or new feature, it goes out to every user through the standard Google Play update mechanism. No subscription check, no paywall on updates.
If you have automatic updates enabled on your device, you'll receive them without lifting a finger. If you prefer manual updates, they'll be waiting for you in the store whenever you're ready.
An app that manages your digital estate should never stop working because a payment lapsed. You paid once — the app is yours, updates included.
No — Mortui is Android only, and there are no plans for an iOS version. This isn't a resource or timeline issue. It's a platform limitation.
Mortui's core functionality depends on capabilities that iOS deliberately restricts for third-party apps:
- • No persistent background execution. Mortui's monitoring service runs continuously in the background, collecting behavioral data every 15 minutes. iOS kills background apps within seconds and offers no reliable equivalent. The system-scheduled alternatives are irregular and entirely at iOS's discretion.
- • No access to app usage or screen activity. The majority of Mortui's behavioral signals — which apps you use, how often you unlock your phone, screen-on time, keyboard activity, and sleep/wake patterns — come from APIs that simply don't exist on iOS. Apple doesn't allow apps to monitor other apps' usage.
- • No programmatic SMS or file access. On Android, Mortui can send SMS messages and delete files automatically in the background. iOS requires user interaction for both — which defeats the purpose of an app designed to act when the user can't.
- • No auto-start after reboot. Android restarts Mortui's monitoring service automatically after a device reboot or app update. iOS has no mechanism for this — monitoring would silently stop until you manually reopen the app.
An iOS version would need to be a fundamentally different product — server-dependent, with far fewer behavioral signals, and significantly less reliable at detecting incapacitation. Rather than ship a compromised version that can't deliver on the core promise, Mortui remains Android-exclusive where the platform allows it to work as designed.
