Discreet emergency mode
An everyday-looking experience designed to allow discreet initiation of a protection protocol when the person cannot openly show they are seeking help.
Technology for personal protection and trust networks
Preparing for controlled beta testing.
Discreet protection when asking for help must be possible.
Angelus Guardian is a technology initiative created to strengthen trust networks and support faster responses in contexts of violence against women, gender-based violence and femicide risk.
Angelus is a complementary support tool and does not replace the police, emergency medical services, firefighters or official emergency services. In immediate danger, also contact your local emergency services.
Two complementary forms of protection
02
Angelus Central
A coordination environment between the protected person and their trusted guardian network, with routines, protection journeys, temporary accompaniment, contextual location and alerts.
Angelus is a complementary support tool and does not replace official emergency services.
When asking for help isn't simple
Some situations don't allow a phone call, a long explanation or visible interaction with your device.
- You can't call or explain what's happening.
- Someone may be watching what you do on your phone.
- A scheduled check-in may go unconfirmed.
- Connection may drop during an occurrence.
- You may need to act discreetly and quickly.
The Angelus approach
Angelus turns discreet actions — an alternate code, a single tap, a missed check-in — into a coordinated protection journey: silent alerts, context shared according to the protocol and follow-up by trusted people.
How it works
Network preparation and discreet response when it matters.
01
Organize your network
The protected person organizes their trusted guardian network.
02
Prepare protection
Prepares a routine or protection journey.
03
Share accompaniment
Shares temporary accompaniment when needed.
04
Guardians receive context
Guardians receive context and alerts according to the protocol.
05
Clear closure
The incident is closed clearly.
Multiple ways to ask for help
Different triggers, manual and automatic, for different risk situations.
Silent SOS
Immediate manual activation.
Duress Code
Enter an alternate code and ask for help without raising suspicion.
Protection journey
Lets you set an arrival time and a tolerance window. If arrival is not confirmed by the deadline, Angelus can notify your configured guardians — without stating a confirmed emergency.
Critical Battery
Guardians can be notified when the device is about to shut down. Available in controlled beta validation.
Connection Loss
The system logs network interruptions during an incident. Available in controlled beta validation.
Automatic Escalation
Resending and broadening alerts when necessary. Available in controlled beta validation.
Protection scenarios
Each situation calls for a different kind of response.
Fictional scenarios show how Angelus protocols and signals can support a trusted network at different moments.

- Under validation
- In development
Angelus protection
Protection comes first. Discreet protocols and protection journeys support the trusted network.
Available in controlled beta validation
Discreet emergency mode
When discreet emergency mode is triggered, the network receives maximum priority — with no visible emergency interface on the device.

In developmentPresentation narrative
Express delivery
Presentation narrative about prioritizing alert delivery through available channels — without promising absolute availability.
1 of 5
Alert generated
An event requires the network to be reached quickly through configured channels.
Protection journey
Marina leaves work at 7 p.m. and schedules her arrival one hour later. If the deadline and tolerance end without confirmation, her network receives an attention notice.
Available in controlled beta validation
Safe Journey
Marina schedules arrival and tolerance; if the deadline ends without confirmation, the network gets an attention notice — not a confirmed emergency.
1 of 5
Scheduling
Before leaving, Marina sets departure, destination and arrival window.
Under validationPresentation narrative
Check-in reminder
A gentle reminder before or at the expected confirmation moment — not an emergency or missed check-in.
1 of 5
Active journey
Marina is close to the agreed arrival time.
Under validationPresentation narrative
Extended journey
Marina consensually changes the active journey deadline; the network sees the new expected time.
1 of 5
Unexpected delay
A legitimate delay requires more time than planned.
Missing confirmation does not prove an emergency — it only signals a pending confirmation.
Follow-up signals
Follow-up signals help the trusted network interpret the quality and continuity of information received.
Under validation
Critical battery
A limited device capacity signal — not a manual trigger.

Trip in progress
Rafaela is still en route with the device active.
Under validation
Connection loss
Network loss during an occurrence; the last known position is preserved.
1 of 5
Stable connection
The device was sending updates normally.
Under validation
Connection restored
Signal returns and updates resume from the latest point — without inventing missing history.
1 of 5
Still offline
The network follows the last known position.

Outdated location
No new ping for a relevant period — distinct from total connection loss.
1 of 5
Recent updates
The network was receiving pings at short intervals.

Location permission lost
The device stopped authorizing location — distinct from temporary inaccuracy or network loss.

Active occurrence
A follow-up session was in progress.
Occurrence lifecycle
Revocation, guardian confirmation, alert delivery and closure — each state has a distinct meaning.

For protected people and guardians
Follow along in the browser, with the Guardian app as a convenience
Protection does not require installing another app. The secure link remains a central option for guardians.
- Guardians can follow along in the browser without creating an account.
- Installing the Guardian app is optional and adds convenience.
- The Guardian app may offer push and incident organization (in development).
- No basic critical guardian access depends on a public commercial offer.
- The protected person uses Angelus on Android (controlled beta); iPhone is in development.
Push notifications and background behavior vary by device, permissions and Beta stage — we do not promise delivery in every scenario without E2E validation.
