Privacy Policy
Effective September 25, 2026
GoFly is private by design. The short version: there are no accounts, and nothing we collect is linked to your identity. We use anonymous analytics to improve the app and Apple's privacy-preserving install attribution to measure our ads. We never read your device's advertising identifier and never ask to track you.
What stays on your device
Everything you enter lives only on your device:
- Calculator inputs (speeds, distances, fuel figures, and similar values).
- Saved aircraft profiles and weight and balance presets.
- App preferences.
None of this is transmitted to us or to anyone else. Deleting the app deletes this data.
Anonymous analytics
GoFly records a small set of usage events, such as which tools are opened, paywall views, completed purchases, and your answers to the optional onboarding questions. Each event carries the app version and a random install ID that GoFly creates on first launch. The install ID is not tied to your name, Apple ID, email, or any other app, and it resets if you reinstall. Events are stored with our database provider, Supabase, and are used only to understand how the app is used.
Advertising measurement
GoFly includes the Meta SDK (FacebookCore) so we can measure installs from our ads on Facebook and Instagram. It sends basic app events, such as app installs, launches, and App Store purchases, to Meta. GoFly turns off collection of Apple's advertising identifier (IDFA), so no cross-app identifier is shared. Install attribution runs through Apple's SKAdNetwork, which reports ad results to Meta without identifying you. Meta's handling of this data is covered by Meta's Privacy Policy.
Weather requests
When you use the METAR decoder, the app sends the airport identifier you typed (for example, KPAO) to the NOAA Aviation Weather Center (aviationweather.gov) to fetch the current report. That request is subject to NOAA's own policies, like any visit to a US government website. GoFly attaches no identifiers or personal information to it.
Purchases
Purchases and subscriptions are processed by Apple through the App Store. We never see your name, email address, or payment details. The app checks your purchase status through Apple's StoreKit framework on the device.
What we don't do
GoFly has no accounts, no ads shown inside the app, and no crash reporters. We do not sell data, and we do not combine GoFly data with data from other companies' apps or websites to track you.
Children
GoFly is not directed at children and does not knowingly collect data from them.
Changes
If the app's privacy behavior ever changes, we will update this page and its effective date before the change ships.
