Morning
The kitchen light came on at 6:10.
Ten minutes earlier than usual, which is how you know it is a good day. Tea on the veranda by half past. The gate opened once, for the milk.
- Kitchen light — 6:10
- Veranda, tea — 6:34

Hope You're Fine
Hope you’refine.
Every day begins with the same thought. Hoyfo quietly lets you know your loved ones are okay.
Works with the cameras and sensors you already ownScroll
Six chapters
What Hoyfo is actually about.
- 01
Parents
For the people who raised you, still living their own day.
- 02
Family
One quiet thread, shared by everyone who worries.
- 03
Home
The house already knows. It just never had a way to say so.
- 04
Care
Attention, not alarm. Presence, not pressure.
- 05
Privacy
Video never leaves the house. That is architecture, not policy.
- 06
AI
Small models, running in the room they're describing.

- Three encrypted snapshotsSealed · expire in 24hToday
No footage to scrub through. No feed to keep up with. The snapshots are sealed, and they expire tomorrow unless someone in your family says otherwise.
How the sealing worksA day, end to end
Nothing happened today. That's the update.
Scroll to move through Tuesday at a house in Thrissur, as a family in three cities received it.
- 01 · 05:00 — 11:00
- 02 · 11:00 — 16:00
Afternoon
Medicines came to the door at 11:20.
The chemist's boy, the same one as always. Lunch a little late. The house is quiet between two and four, the way it has been every day this month.

Evening
Dad returned home at 6:40.
Back from the walk he has taken since he retired. Two neighbours at the gate for a while. Lights on across the front of the house by seven.
- Gate — 6:40 pm
- Visitors at gate — 6:44 pm
- Front lights — 7:02 pm
- 04 · 21:00 — 05:00
Night
The house settled at 10:15.
Doors checked, lights down, nothing moving after quarter past ten. Hoyfo rests until morning. Nothing is read, nothing is recorded, nothing is sent.
- Doors closed — 10:09 pm
- House settled — 10:15 pm
- Hoyfo resting — 10:30 pm
Compatibility
Works with thecameras and sensorsyou already own.
Most homes with older parents in them are already instrumented — CCTV at the gate, a contact on the front door, a smoke alarm in the kitchen. Hoyfo reads the cameras over ONVIF and RTSP and the sensors over Zigbee, Z-Wave, Matter or MQTT. Nothing new goes on the wall, and the recorder keeps doing exactly what it does now.

Beyond the camera
Some of the most useful signals in a house never had a lens.
Door contacts
Gate and front door, opened and closed
Window sensors
Left open after dark
Smoke & heat
Alarm state, battery, last self-test
Motion (PIR)
Rooms waking and settling
Gas & LPG
Kitchen leak detection
Water leak
Bathroom and utility
Temperature
Heat that an older body shouldn't sit in
Smart plugs
The kettle, the geyser, the fan
Nothing on the wall changes. Only what it is for.
No cameras at all?
Hoyfo runs on sensors alone. You lose the snapshots and keep everything else — the daily lines, the routine, the escalation when a pattern breaks.

Privacy
We built itso we couldn'tlook.
Every company in this category promises not to look at your video. We removed the possibility instead — which is a harder thing to build and a much easier thing to trust.
Video never leaves your home.
Streams are read on the Hub, in the house, and the frames are discarded as they are read. There is no upload path for footage, because we never built one.
Guardian Cloud cannot read photos.
What we route is a sealed envelope. We can see that it exists and where it is going. We cannot open it — not for a partner, not for a subpoena, not for ourselves.
Only your family holds the keys.
Keys are generated on your Hub and shared directly with your family's devices. If every server we own were taken tomorrow, not one photograph would be exposed.
The architecture
How Hoyfo works.
Four steps, and only one of them touches the internet. The interesting design decision is what is missing: there is no place in this diagram where video is stored.
01
Cameras & sensors
Whatever the house already has — CCTV at the gate, a contact on the front door, the smoke alarm in the kitchen, a motion sensor in the hall. Nothing new is mounted, nothing is rewired.
02
Hoyfo Hub
A small box beside the recorder reads the streams and the sensor traffic locally, and turns both into short, plain sentences. Frames are discarded as they are read.
03
Encrypted mailbox
Sealed envelopes are posted to Guardian Cloud, which can route them but cannot open them. No video is ever uploaded.
04
Family
Your phone holds the keys. The envelope opens on your device and becomes a line you can read in four seconds.
The long version
Setup takes an afternoon · No technician required
Families
The distancedidn't change.The worry did.
“My parents don't answer every call anymore. Now I don't worry.”
Nikhil V.London / Thrissur
Two missed calls used to mean a bad afternoon. Now I open one line before my first meeting and the rest of the day belongs to me again.
“I stopped calling to check. I call to talk.”
Sana K.Singapore / Lucknow
The checking used to eat the whole conversation. We spent ten minutes establishing that everything was fine and then hung up. Now we just talk.
“Appa said yes because nobody was watching him.”
Meera J.Melbourne / Madurai
He refused a camera in the house for years, and he was right to. What changed his mind was that the video stays in his house. He shows people the box now.
The mission
Help families knowtheir loved onesare okay.
No new hardware. No storage subscription. No surveillance. Just the small, ordinary certainty that today went the way it usually does.
