Krafthome — Privacy Policy
Last updated: 3 November 2026
Krafthome is home control for your house: an app for iPhone, iPad and Mac, and a hub you run on your own home network. This policy describes what each does with your information. There is no Atemkraft account, no analytics and no advertising, in the app or on the hub.
What the hub keeps, and where
The hub is a computer in your house. Everything Krafthome knows lives on it, in your home, and nowhere else:
- Your devices: their names, rooms, state and history (power, temperatures, on and off), and the activity log of who did what.
- The people in your house: their names, PINs (stored only as a hash), and each person's layout, alert choices and quiet hours.
- Passwords and sign-ins for the services you connect (for example iCloud with an app-specific password, Spotify, Tesla, and sites you sign in to), kept in a folder only the hub can read. They are never sent to the app.
- From your iCloud mail and calendars, when you connect them: your calendars' events, and the text of shipping, order and travel emails only. Other email is read on the hub to find those, and not kept.
What the app keeps
The app keeps the address of your hub and its own sign-in to it, in the device's keychain. Apple Reminders, Notes and the calendars the hub can't see, which you can choose to show, are read on the device and never sent to the hub or anywhere else.
What goes to other services, and when
- The services you connect. The hub talks to each device's maker's service, or to the device on your network, to read and control it, and to the accounts you connect (iCloud, Spotify and the like) to do what you asked.
- Tracking parcels and flights. For your parcels and flights, the hub asks carriers, airlines, airports, OpenSky Network and adsbdb.com for their status, by tracking or flight number, and reads their public status pages. Nothing else about you goes with it.
- Weather comes from a public weather service, asked for your area.
- Alerts reach your phones through Apple's push notification service.
- The home agent and the parcel agent, only if you turn them on, send readings from the house, your calendar and parcels, and the text of shipping emails to Anthropic's Claude, using your own Anthropic account or subscription, to write a briefing, suggestions and parcel updates.
- Remote access, only if you turn it on, goes through Atemkraft's relay at remote.atemkraft.dev, encrypted end to end with a key per device that the relay never sees. The relay keeps a random id for your hub and when it last connected: no name, email or house data.
What Atemkraft receives
Nothing, unless you write to us or turn on remote access as above. TestFlight and the App Store may share crash reports with us if you choose to send them through Apple.
Your control
- Disconnect any account in the app's Settings, and the hub forgets its sign-in and what it brought in.
- Anything that came from your accounts can be made private to you, or removed.
- Turn off the agents, alerts and remote access at any time.
- Everything else is on your own hub, which you can wipe or switch off.
Children
Krafthome is for the adults of a household. Its sitter mode limits what a screen shows and does for anyone else; it does not collect information about children.
Changes
If this policy changes, the date at the top changes with it.
