Your house stays yours
Flight Day collects no data. No accounts, no analytics or telemetry, no tracking and no Flight Day cloud. Nothing is sent to us, so there’s nothing to sell. This page lists what each part does talk to, and why.

The short version
- No data collected. No accounts, no analytics or telemetry, no crash reporting, advertising or tracking code in any Flight Day app, and no Flight Day cloud. The Apple apps declare no tracking and no collected data.
- Your data stays in your house: in your Home Assistant, on the optional Flight Day Hub on your own computer, and on each screen.
- Public services get only what they need: launch schedules, the ISS position and NASA pictures need nothing personal. Weather services get your home’s location.
- Apple Health is opt-in, read-only and stays home. See Apple Health.
- This website has no cookies, no analytics and loads nothing from anyone else.
Where your data lives
| Place | What’s there |
|---|---|
| Your Home Assistant | The house: devices, calendars, wake times, the alarm and who’s launching. |
| Flight Day Hub (optional), on your own computer | Screen settings, caches of public space feeds, pictures and news, and shared sleep summaries, which expire after 48 hours. |
| Each wall panel and TV | Its settings and the addresses and keys for your house, in the app’s private storage. |
| Each Apple device | The addresses and keys for your house in the Keychain. With iCloud Keychain on, Apple syncs them, encrypted, to your other devices. The Watch gets its settings from your iPhone. |
What each part talks to
Besides your own Home Assistant and hub, these are the public services Flight Day contacts. Any service you contact can see your home’s internet address.
Wall panel and TV app
| Service | What’s sent | When |
|---|---|---|
| Open-Meteo (api.open-meteo.com) | Your home’s latitude and longitude, and units | The forecast, every 15 minutes |
| US National Weather Service | Your home’s location, rounded to about 100 m | Weather alerts |
| Launch Library 2, Spaceflight News, Where the ISS at? | Nothing personal | Only when no hub answers |
| NASA (api.nasa.gov, images-assets.nasa.gov) and launch image hosts | Nothing personal | Background pictures |
| YouTube | Nothing personal; YouTube may set cookies in the player | Only Live ambient (off by default) or when you choose Watch |
| A public internet radio stream | A request for the stream | Only for the Rain sleep sound |
| AccuWeather | Your home’s location, in the link | Only when you tap Open in AccuWeather |
On Android, the app lets requests through only to these public services and your home network.
Apple apps
| Service | What’s sent | When |
|---|---|---|
| Launch Library 2, Spaceflight News, Where the ISS at?, NASA | Nothing personal | When the hub doesn’t answer |
| Open-Meteo and the US National Weather Service | Your home’s location, rounded | The forecast, rain soon and alerts |
| apple.com | Nothing | A reachability check on the Status screen |
| YouTube, AccuWeather | The video, or your home’s location in the link | Only when you tap |
When you sign in to Home Assistant from an Apple app, your Home Assistant may check flightday.app to confirm the sign-in address. The app itself doesn’t contact flightday.app.
Flight Day Hub
| Service | What’s sent | When |
|---|---|---|
| Public space and news feeds: Launch Library 2, Spaceflight News, NASA, CelesTrak, JPL, public news and AI-news feeds | Nothing personal | Regular polling; the news list is configurable |
| YouTube pages | Nothing personal | Finding live launch streams |
| Apple WeatherKit | Your home’s location and country | Only with your own WeatherKit key, at most every 5 minutes |
| Anthropic and OpenAI | Your own sign-in, to read how much of your plan is left | Only if you turn on plan limits (off by default) |
Apple Health (HealthKit)
On iPhone, Flight Day uses HealthKit to read your sleep from Apple Health, to show last night in the briefing and the night view. It’s off until you turn it on.
- Read only, sleep only. It reads HealthKit Sleep Analysis for the last 8 days. It never writes anything to Apple Health.
- It stays on your iPhone. Your iPhone works out nightly summaries. Raw Health samples never leave the phone.
- Sharing is a second switch. If you turn it on, the summary goes only to your own Flight Day Hub: a random id, a name you choose, last night’s bed and wake times, minutes asleep, in bed and awake, sleep stages, a 7-day average and the number of nights.
- On the hub, reading it needs the hub’s key. It expires after 48 hours, is deleted when you turn sharing off, and is never logged.
- Who sees it: anyone looking at a house screen when it shows last night.
- It never goes to us, and it leaves your home network only if you reach your hub from outside yourself.
Permissions
The Apple apps ask for each permission only when a feature first needs it: Calendar, Notifications (for the alarm), Local Network (to find Home Assistant) and HealthKit (sleep, read-only).
- Calendar: the apps read your device calendar (the next 7 days) for Today and the briefing. They write to it only when you add an event yourself. Everything stays on your device and in your own calendar account; nothing is sent to us.
- Health (HealthKit): read access to sleep only. No permission to write to Health is requested. See Apple Health.
- Camera: none. “Live view” means watching your own home cameras through Home Assistant.
- Notifications: local only, for the alarm. No push service.
- Location: none. Your home’s location comes from Home Assistant or what you type in.
- Local network: to find your Home Assistant.
- Android accessibility service: it sees only which app is in front, so the TV can return to Flight Day. It can’t read what’s on screen.
AI features
Flight Day has no AI service and no AI keys of its own. When released, AI features go through the AI provider you choose in your Home Assistant, and what they send is listed with each feature. In the one household that runs Flight Day today, the AI line in the briefing sends only public headlines, the house check (in development) sends device findings with names and addresses removed, and the AI comfort plan (in development) sends room readings, temperatures, wake times and calendar busy times without titles.
Apple Weather
When a forecast or the next-hour rain line comes from Apple’s WeatherKit, the screen shows the Apple Weather mark and a link to Apple’s legal attribution for weather data, wherever that data appears. WeatherKit is used only through your own Home Assistant, or through the hub with your own WeatherKit key.
Worth knowing
- Weather needs your location. Open-Meteo, the National Weather Service and, if you set it up, Apple WeatherKit get your home’s coordinates. The wall and TV app sends them unrounded today; rounding them is planned.
- The Rain sleep sound streams from a public internet radio station. A built-in sound is planned.
- YouTube may set cookies when Live ambient or Watch plays a stream.
- On your home network, the hub’s space data and screen settings can be read without a key. Only sleep summaries need one.
- AccuWeather and Apple Weather through Home Assistant are fetched by Home Assistant, not by Flight Day. Flight Day only reads what your Home Assistant already has.
