Enterprise-grade. Family-simple.

The platform behind the peace of mind

When you trust a system with your family's safety, the technology behind it matters. Signal Homecare is built on security, privacy, and reliability standards you'd expect from a bank — wrapped in an experience that's as simple as checking the weather.

Security that never sleeps

Every layer of Signal Homecare is designed to keep your family's data safe — from the sensors in the home to the app on your phone.

Mutual authentication

The hub and our servers verify each other's identity before sharing any data — preventing anyone from intercepting or impersonating either side.

Every connection between the in-home hub and our servers is mutually authenticated with replay protection. Both sides prove their identity before any data is exchanged — preventing impersonation and man-in-the-middle attacks.

Multi-factor authentication

Sensitive actions like changing alert contacts require an extra verification step — just like your bank does for important transactions.

Your account is protected with step-up authentication for sensitive actions. Email-based one-time passcodes are required when changing alert contacts, managing devices, or modifying security settings — the same rigour you'd expect from your bank.

Device and session management

See every device signed into your account at a glance. Revoke access to any session instantly. Trusted device recognition, forced logout, and session limits give you complete control over who can see your family's information.

Immutable audit trail

Every important action is permanently recorded in a log that can't be altered or deleted — complete transparency and accountability.

Every sensitive action — from changing alert contacts to modifying settings — is permanently recorded in a tamper-proof, append-only log. Full transparency, full accountability, always.

Signed software updates

Every update to the hub is verified as genuine before it's installed — nothing runs unless it's been checked and approved.

Every update to the in-home hub is cryptographically signed, staged through controlled rollout phases, and version-tracked with a full inventory. Nothing runs on your hub unless it's genuine and verified.

Verified from source to home

We verify every component of our software at every stage — from development to your home. Nothing untested reaches your system.

Our CI/CD pipeline is hardened against tampering at every stage. Dependencies are pinned and verified, builds are reproducible, and every deployment is traceable from source code to your home.

Security event monitoring

We actively watch for suspicious activity and block threats before they become problems.

Centralised detection for abuse patterns including brute-force attempts, credential stuffing, and anomalous access. Our operations team monitors a dedicated security dashboard so threats are caught before they become problems.

Automated backup verification

We regularly test that our backups can be restored — so if anything goes wrong, recovery is proven to work.

Backups are only trustworthy if restore is proven to work. Automated restore jobs run on a schedule in an isolated environment, verifying data integrity — so we know recovery works before we ever need it.

Settings history and instant undo

Every settings change is tracked, and any version can be restored instantly if something doesn't work as expected.

Every change to endpoint configuration is versioned with full diff history. Configurations are validated before being applied, and any version can be rolled back instantly. Drift detection catches mismatches automatically.

Simple setup, serious safeguards

Getting started with Signal Homecare is straightforward — but behind the simplicity, every step is carefully secured.

Two-step QR home claim

Scan a QR code and enter a short pairing code to securely link your account to a home — no shared passwords needed.

Each home is claimed through a secure two-step QR code flow with cryptographic verification. The process binds a physical hub to a specific account — no shared passwords, no guessable codes, no room for impersonation.

Secure email invitations

Family members receive a secure, one-time email invitation. Each link can only be used once and expires automatically.

Family members are added through cryptographically signed, time-limited email invitations. Each invite is single-use and expires automatically — ensuring only the intended recipient can join, and only within a controlled window.

Temporary installer access

Installers get limited, temporary access that expires automatically — no permanent access, no visibility into your history.

Installers and support staff receive time-boxed, minimal-privilege access that expires automatically. No permanent broad access, no visibility into historical data — just what's needed, for exactly as long as it's needed.

Multi-home support

Caring for more than one person? Switch between homes from a single account with clear navigation, unambiguous context, and strict data boundaries. Notifications and views are always scoped to the home you're looking at.

Consent and authority tracking

The system records who authorised setup, on what basis, and which versions of privacy notices and terms each person has seen and accepted. Admins can see where records are missing or outdated — full compliance visibility at a glance.

Safe account closure

Closing a home follows a careful process with safety checks to prevent accidental deletion. All data and access are properly removed.

Decommissioning a home follows a controlled workflow with a retention hold period before final deletion. All credentials, invites, and notification routes are revoked. Typed confirmation and step-up authentication are required — no accidental deletions.

Intelligent, thoughtful alerting

Signal Homecare doesn't just send notifications — it sends the right notification, to the right person, at the right time, with a clear explanation of why.

Alert chain — the right person, every time

Set who gets notified first, and who to contact next if there's no response. You can also set quiet hours for overnight.

Set primary and secondary contacts for each home. Define escalation rules so that if the first person doesn't respond, alerts are automatically passed to the next. Schedule quiet hours to avoid unnecessary disturbances overnight.

Real-time in-app notifications

Alerts arrive on your phone instantly, the moment something needs your attention.

Alerts arrive instantly over a secure WebSocket connection — no polling, no delays. Future email notifications are built into the architecture and ready to activate.

Explainable alerts

Every notification tells you exactly why it was triggered — in plain language. You'll see what was expected, what was observed, and a confidence level. No opaque alerts, no guesswork. Just clear, trustworthy information.

Improve alerts with your feedback

If an alert doesn't seem right, tell Signal Homecare why — it learns from your feedback and gets better over time.

If an alert doesn't feel right, tell Signal Homecare why — choose from structured categories like "visitor present", "routine change", or "one-off event". Your feedback helps Signal Homecare learn and improve over time, within safe, bounded limits.

Visitor and carer scheduling

Mark when a carer, cleaner, or family member is expected — as a one-off or recurring schedule. Signal Homecare adjusts its awareness during those windows, reducing false alerts and keeping monitoring intelligent and context-aware.

Bathroom and long-stay detection

If someone has been in the bathroom longer than usual, Signal Homecare can alert you — especially important overnight when falls are more common.

Configurable rules for the bathroom — including overnight presence detection and adjustable long-stay thresholds. Day and night sensitivity can differ, and the system only activates when adequate sensor coverage is in place.

Daily intelligence, not just data

Signal Homecare doesn't overwhelm you with raw sensor readings. It distils the day into a calm, clear picture.

  • Daily digest

    A calm, once-a-day summary of how the day went — based on what actually happened, not guesswork. No need to open the app constantly. If everything seems normal, you'll know. If something was different, you'll see exactly what.

  • Weekly routine drift summary

    A weekly view of how routines are shifting over time — comparing the current week to what's normal for this home. Gradual changes that are impossible to spot day-to-day become visible at a glance.

  • Sensor health monitoring

    Battery levels, connectivity, and maintenance needs are tracked proactively by our operations team. If a sensor needs attention, we'll know before it becomes a gap in coverage — and we'll sort it out, so you don't have to.

Your data. Your rights. Built in.

Your data rights aren't an afterthought — they're built into every part of the system. Every data right is a working feature, not a policy document.

Data export

Request a complete, machine-readable export of your home's data at any time. Downloads are scoped to your home, redacted where necessary, and delivered via a secure, time-limited link. Every export is fully audited.

Controlled deletion

Home offboarding follows a deliberate workflow — a retention hold period, credential revocation, and final deletion with typed confirmation. No accidental data loss, no orphaned records, no uncertainty.

Consent tracking

Every version of our privacy notice and terms is tracked, and every acceptance is recorded with a timestamp. Admins can see at a glance where records are missing or outdated — verifiable compliance, not guesswork.

Sign in with what you already use

Sign in with your Google account — no new passwords to remember, no separate credentials to manage. No new passwords to remember — your existing Google account handles the login securely.

Your Google credentials are never stored by Signal Homecare. Login happens directly with Google, and only your name and email address are shared — nothing else.

Built for families. Secured like a bank.
