How the harvest actually works

Voice assistants

Wake-word devices stream audio snippets to the cloud. Human contractors have reviewed private recordings. Transcripts feed ad profiles.

Cloud cameras & doorbells

Footage is stored on corporate servers, has been shared with third parties without warrants, and can be mined by AI training pipelines.

Presence & thermostats

Occupancy schedules reveal when you sleep, leave, and return. That behavioral data is gold for brokers — and burglars if breached.

App telemetry

Companion apps bundle trackers that fingerprint your phone, location, and habits — even when you never open them.

Why open source wins on security

Auditable code

Anyone can read the source. Backdoors and trackers have nowhere to hide when thousands of eyes review every commit.

Local-first by design

Home Assistant, MagicMirror², ESPHome — all run entirely on your hardware. If the internet dies, your home keeps working.

Community over corporation

No shareholder pressure to monetize your data. The roadmap is driven by users, not ad revenue targets.

Repair & modify freely

No bricked devices when a company “sunsets” a product. You own the firmware, so your hardware lives as long as you want.

The Data Sovereignty Pledge

Every system we sell runs fully offline — the internet is optional, never required.

We will never collect, sell, or share your household data. We couldn’t if we wanted to: it lives on your hardware.

All software we ship is open source and independently auditable.

You own your hardware outright — no rentals, no forced subscriptions, no remote kill switches.

If we disappear tomorrow, your home keeps working forever.

Make your home sovereign
