SimpleAvWxPrivacy Policy
Effective [[TODO: effective date]] · Applies to the SimpleAvWx app for iPhone and iPad and this website (simpliflypilot.com).
SimpleAvWx is published by Simplifly LLC (“we”). This policy explains what the app does with information.
- No account, no ads, no analytics, and no tracking.
- Your location never leaves your iPhone. It's used only for the map.
- Your saved airports and settings sync through your own private iCloud, which we can't access.
- To get weather, the app sends airport codes and airport search text to our server and to the weather data services listed below. Our server keeps request logs (IP address and the requested airport code or search text) for 14 days, then deletes them.
Information stored on your device
- Your airports and settings — the airports you save, My Trip, favorites, display settings, and the last map position. These are stored on your device. If iCloud is on for your Apple Account, Apple's iCloud (CloudKit) syncs them to your other devices through your own private iCloud database. Simplifly LLC can't access that data.
- Imported schedule — if you import a schedule, the file's sequences, dates, flight numbers, and airports are saved on your device only.
- Calculator values — last values in the calculators and side slider, saved on your device.
Location
If you allow it, the app reads your location while you're using it (it asks iOS for accuracy of about 3 km), only to center the map around you and show your position on the map. It never asks for “Always” access. Your location never leaves your device: the app does not send it to us or anyone else. You can turn location off any time in Settings → Privacy & Security → Location Services → SimpleAvWx. Everything except “Near Me” works without it.
What the app sends over the internet
To get weather and airport information, the app makes requests to these services. They receive what's needed to answer the request. Like any internet service, they also see your device's IP address.
| Service | What is sent | Why |
|---|---|---|
| SimpleAvWx server (avwx.simpliflypilot.net, operated by us) | Airport codes (ICAO/IATA) and airport search text | METAR, TAF, D-ATIS, RVR, airport search and runway data, and matching schedule airports. The server gets the weather itself from NOAA's Aviation Weather Center (aviationweather.gov) and FAA data feeds; your IP address isn't passed on to them. |
| Apple — Apple Weather (WeatherKit) | The airport's coordinates | Hourly and 10-day outlook |
| Apple — Maps and geocoding (MapKit / Core Location) | Map areas you view; an airport's coordinates | Map display and the airport's time zone |
| Apple — iCloud (CloudKit) | Your saved airports and settings (only if iCloud is on) | Sync between your devices |
| NOAA / National Weather Service map services | The map area you're viewing | Radar images |
| Iowa Environmental Mesonet (Iowa State University) | The map area you're viewing | Radar images and storm cell tops |
| NOAA GOES data on Amazon Web Services | Nothing about you (a request for recent files) | Lightning |
| avwx.rest (NOTAM data service) | Airport codes | NOTAMs, when that feature becomes available in a later version. The current version of the app doesn't contact avwx.rest. |
The app does not send your name, email, contacts, location, device identifiers, or advertising identifier to any of these services. Apple handles data under its own privacy policy. The NOAA and Iowa State services are public data services with their own policies.
Our server
Our server answers weather and airport requests. For security and operations (for example, stopping abuse and fixing problems), it keeps request logs containing your device's IP address, the time, and the requested airport code or search text. Logs are kept for 14 days and then deleted. They're used only for security and operations.
The server also archives weather reports (METARs and TAFs) for future features. These are public weather observations and forecasts, not information about you, and they don't include IP addresses or anything else about who requested them.
What we don't do
- No account or sign-in.
- No advertising, and no advertising identifier.
- No analytics or crash-reporting SDKs.
- No tracking across other companies' apps or websites, and no data brokers.
- No in-app purchases. [[TODO: re-check if pricing changes]]
If you contact us
If you email support, we receive your email address and whatever you include. We use it only to reply and fix the problem, and we delete it within [[TODO: retention period]] unless we need it longer to resolve your request.
This website
This site has no cookies, analytics, or tracking scripts. Our web hosting provider (Hostinger) may log visitors' IP addresses for security, under its own policy.
Keeping and deleting your information
- Server request logs are deleted automatically after 14 days.
- Delete airports in the app, or tap Remove Schedule in Settings to delete the imported schedule.
- Deleting the app removes the data stored on that device.
- To remove synced data from iCloud, go to Settings → [your name] → iCloud → Manage Account Storage (or Manage Storage) → SimpleAvWx, or turn off iCloud for the app.
- To revoke location access, use Settings → Privacy & Security → Location Services.
- For anything else, or to ask us to delete support emails, write to support@simpliflypilot.com.
Children
SimpleAvWx is meant for pilots and aviation enthusiasts and isn't directed at children. We don't knowingly collect personal information from children.
Changes
If we change how the app handles information, we'll update this page and its effective date before the change takes effect.
