Privacy policy

The short version

Flight Whisperer only keeps what it needs to tell you when a plane is overhead: an approximate location and a way to send your browser a notification. There are no accounts, names or email addresses. Unsubscribing deletes it all.

What we store

• Your location, rounded to about 1 km (two decimal places), plus a label such as "Current location" or the city you picked. Used only to match aircraft passing near you.
• A push subscription: the address your browser provides so we can send it notifications. It doesn't identify you personally.
• A random device token, kept in your browser's local storage, so this device can manage its own alerts. It isn't a cookie and isn't used for tracking.

Third-party services

• Open-Meteo receives the text you type in the city search, to look up places. Using your device's location instead skips this.
• Your browser's push service (run by Google, Apple, Mozilla or Microsoft, depending on your browser) delivers notifications to your device.
• OpenSky Network supplies flight positions. Your data isn't sent to them.
• Flightradar24 opens when you tap a notification, and their own privacy policy applies there.
• Cloudflare hosts this site and provides privacy-friendly Web Analytics, which counts page visits without cookies.

What we don't do

• We don't sell or share your data.
• We don't use advertising or tracking cookies.
• We don't ask for your name, email or phone number.

Deleting your data
